APPENDIX 10(to Section 5.28)

STANDARDS TO REJECT ROPES OF HOISTING EQUIPMENT

1. Rejection (discarding) of ropes applied in operating hoisting equipment shall be performed in accordance with the Guidelines on the hoisting unit operation (Operation Manual), which shall be developed on the basis of ISO 4309 requirements.

If there is no appropriate section in the Operation Manual, rejection of ropes of a hoisting unit shall be carried out in accordance with this Appendix.

The following criteria shall be applied to assess safety of the rope application:

a) The nature and number of wire breaks (Figures from 1 to 3), including presence of wire at rope terminations, presence of wire break accumulations, the intensity of the wire break number increase;

Figure 1. Breaks and displacements of wires in a rope of a regular lay.

Figure 2. Combination of wire breaks with wear-out:

a) in a regular lay rope;b) in a long lay rope

Figure 3 Wire breaks within the area of an equalising block:

a) in several rope strands;b) in two strands in combination

with local wear-out.

b) A brake of a strand;c) Surface and internal wear-out;d) Surface and internal corrosion;e) Reduction of the rope diameter, including a break of the core;

133

f) Reduction of the rope wires cross section area (loss of internal cross section);g) Displacement in the form of corrugation, wage shape, extrusion of wires and

strands, squashing of strands, breaks, bends, etc.;h) Damage resulting from temperature impacts or electric arc discharges.

Figure 4. Wear out of external wires in a regular lay rope:

a) small flat spots on wires;b) increased length of flat spots on

separate wires;c) lengthening of flat spots on

separate wires, with a visible reduction of the wire diameters;

d) flat spots on all the wires, reduction of the rope diameter;

e) intensive wear-out of all external wires of the rope (wire diameters decrease by 40%)

Figure 5. Surface corrosion of wires in a regular lay rope:

a) initial oxidation of the surface;b) general oxidation of the surface;c) visible oxidation;d) high oxidation;e) intensive corrosion.

Notes:1. n is the number of bearing wires on external strands of a rope; d is the rope diameter, in

millimetres.2. Filling wires are not considered bearing ones, thus are not liable to accounting. In ropes with

several layers of strands, wires of the visible external layer are accounted only. In ropes with a steel core, the latter is considered as an internal strand, and hence is not accounted.

3. The number of visible breaks in strand design ropes shall be calculated in accordance with established equations. The obtained value shall be rounded to a whole number towards the larger one.

4. For ropes with different diameters of outer wires in external strands, the design class has been reduced in the Table and marked with an apteryx. If a rope operates only or partially with blocks of synthetic materials or metal blocks with synthetic lining, a considerable number of wire brakes inside the rope prior to occurrence of visible break indications or intensive wear out of the external surface is more characteristic [further text is illegible].

2. Ropes that operate with steel and cast iron blocks shall be rejected on the basis of the number of wire breaks in accordance with Table 1.

Ropes of hoisting equipment designed to lift people, as well as those applied to transport melted or glowing metal, flammable and toxic substances, shall be rejected if the number of wire breaks is twice less.

3. If the rope diameter decreases due to surface wear-out (Figure 4) or corrosion (Figure5) by 7% and more as compared with the rated diameter, the rope shall be rejected even if there are no visible wire breaks.

135

If the rope diameter decreases due to damage caused to the core, e.g., internal wear-out, squashing, break, etc. (by 3% of the rated diameter for non-whirling ropes, and by 10% for other ropes), the rope shall be rejected even if there are no visible wire breaks (Figure 6).

Figure 6. Local rope diameter decrease at the location of the organic core damage.

If a rope reveals surface wear-out or corrosion of wires, the number of brakes serving as an indication for rejection shall be reduced in accordance with data of Table 2

8575706050

If the original diameter of external wires decreases by 40% and more as a result of wear-out (Figure 4) or corrosion (Figure5), the rope shall be rejected.

Wear-out and corrosion of wires on the basis of their diameter shall be identified utilising a micrometer or other instrument, which provides analogous accuracy.

If the number of wire breaks is below the values specified in Table 1, as well as if the wire surfaces are worn out without breaks, a rope may be accepted for operation provided that its condition is thoroughly monitored and periodically inspected, and the results are recorded in the inspection logbook. The rope shall be replaced as the wear-out level specified in Table 2 is achieved.

If loads are suspended on two ropes, each of them shall be inspected and rejected separately, and replacement of only one rope, the mostly worn-out one, may be accepted.

4. To assess conditions of internal wires, i.e., to control the loss of the metal part of the rope cross section (loss of internal cross section), which may be caused by breaks, mechanical wear-out and corrosion of wires in internal layers of strands (Figure 7), the rope shall undergo flaw detection along its whole length. If a

136

flaw detector identifies a loss of wire metal cross section, which reaches 17.5% and above, the rope shall be rejected.

Figure 7. Decrease of the wire cross section area (intensive internal corrosion)

5. If one or several broken strands are identified in a rope, the rope shall not be accepted for further operation.

Figure 8. Corrugation of a rope (see the text for description).

6. Rope corrugation is characterised by the pitch and direction of its coil (Figure 8). If the direction of the corrugation coil and that of the rope lay coincide, and the pitch of the corrugation coil (Hв) and that of the rope lay (Hk) are equal, the rope shall be rejected at dв1.08dk, where dв is the diameter of the corrugation coil, and dk is the rated diameter of the rope.

If the directions of the corrugation coil and rope lay do not coincide, and the pitch of the corrugation coil and that of the rope lay are unequal, the rope shall be rejected at dв4/3dk. The length of the rope section under inspection shall not exceed 25 dk.

7. Ropes shall not be accepted for further operation if the following is found:

- basket-shaped displacement (Figure 9);- core extrusion (Figure 10);- strand extrusion or separation (Figure 11);- local increase of the rope diameter (Figure 12);- local decrease of the rope diameter (Figure 6);- squashed areas (Figure 13);- kinks (Figure 14);- breaks (Figure 15);- bends (Figure 16);- damage resulting from temperature impacts or electric arc discharges.

INTERNATIONAL STANDARDS ISO 4301/1, 4302, 4308/1, 4308/2, 4310 and 8087

INTERNATIONAL STANDARD ISO 4301/1 (CRANES AND LIFTING UNITS. CLASSIFICATION. PART 1. GENERAL PROVISIONS).

Introduction

Load-lifting cranes (hereinafter “cranes”) are applied to lift and relocate loads, weights of which do not exceed their rated load-lifting capacities. Cranes of one type (e.g., overhead travelling ones) and cranes of different types (e.g., a tower crane for construction and a port crane with a considerable lifting capacity) may have different operating conditions. Crane designing shall account for conditions of operation to ensure the required level of safety and durability that will comply with the requirements of the customer. Classification is a system that is used as a tool to establish an effective basis to design structures and machines, and as a basis to develop relations between the Customer and Producer. The Classification will assist in selecting a particular crane for the envisaged type of work.

The Classification reviews such operating conditions only that are not dependent on the crane type and the ways of its control. Further International Standards will establish the portions of the classification line that will be applicable to various crane types (i.e., overhead travelling, self-propelled, tower, etc.).

This International Standard establishes crane classification and forms a part of ISO 4301 International Standard.

A complete list of ISO 4301 parts is as follows:

Part 1. General Provisions.Part 2. Self-Propelled Boom Cranes.Part 3. Tower Cranes.Part 4. Portal and Pedestal Cranes.Part 5. Overhead Travelling and Gantry Cranes.

1. Purpose and Scope of Application

This International Standard establishes crane classification on the basis of operating cycles performed during an expected period of the crane service, and the load distribution factor, which represents rated loading conditions.

This Standard does not assume that the same method of load modelling or testing method will be applicable to all types of devices included into ISO/TK 96 assortment.

139

2. Application of the Classification

In practice, the Classification may have two ways of application that may be considered separately.

2.1. General Classification of a Lifting Unit

The first application of the Classification will allow the crane Purchaser and Producer to achieve an agreement about operating conditions of that particular crane. Hence, it is a contractual and technical reference matter, and is used for designing. The classification method is represented in Section 3.

2.2. Classification for Designing Purposes

The second application of the Classification will allow the Designer to analyse the project on its basis, and prove that the crane under his design is able to operate during a certain service period in certain operating conditions established for that particular type of application.

The Designer will receive the data of load distribution submitted by the Customer or provided by the Producer (in case of serial equipment designing), include them into initial data, on which his analysis will be based, and considers the factors that govern sizes of the crane parts.

The form of load distribution requisition, on the basis of which the required data may be identified, is to be developed in one of future International Standards.

3. Crane Classification Groups in General

To identify a group the crane refers to, it is required to consider the class of application and loading conditions.

3.1. Application Class.

The Customer expects that during the service period the crane will perform a certain number of operating cycles, which is one of the main parameters for classification. In specific types of work (e.g., in bulk unloading by way of a gripping device), the number of cycles may be obtained if the summarised number of operating hours and the number of operating cycles per hour are known. In other cases, e.g., when self-propelled cranes are considered, the total number of operating cycles is more difficult to obtain, as such cranes are used in various conditions; in this case appropriate values shall be obtained by experiment. The total number of operating cycles is a sum of all operating cycles per a certain period of the crane service.

Economic and engineering factors, influence of the environment and obsolescence shall be taken into account when identifying a crane service life.

140

The total number of operating cycles depends on the frequency of the crane usage. For the sake of classification, the whole range of potential operating cycle numbers has been divided into ten application classes (Table 1). The operating cycle commences, when a load is ready for lifting, and completes, when the crane is ready to lift the next load.

3.2 Loading Conditions.

Another basic parameter of classification is that of loading conditions. Loading conditions are related to the number of load lifts, while the load is of a particular weight expressed in parts of the crane load lifting capacity. Table 2 shows the rated values of load distribution factors for a crane (Kp), and each of them characterises a corresponding loading condition.

Cranes that systematically lift light loads, and rarely nominal loads.Cranes that systematically lift average loads, and rather often nominal loads.Cranes that systematically lift heavy loads, and often nominal loads.Cranes that systematically lift loads close to nominal.

If numbers and weights of loads that are lifted during the crane service life are not available, selection of the appropriate loading class shall be agreed between the Producer and Customer.

141

If exact information about the numbers and weights of loads that are lifted during the crane service life is known, the ratio of load distribution for the crane may be modelled in the following way:

The load distribution factor for the Kp crane shall be obtained utilising the following equation:

where Ci is the average number of operating cycles, with particular levels of the load weight, = C1, C2, C3, …, Cn;CT, is the total number of operating cycles with all the loads:= CT, = C1, + C2, + C3, + …, + Cn;Pi are values of separate load weights (load levels) for a typical application of the particular crane:Pi = P1, P2, P3, …, Pn;Pmax is the weight of the largest load (nominal, rated load) that is acceptable for the crane to lift;m = 3

Detailed, equation (1) shall look as follows:

The rated value of the load distribution factor for a crane shall be established on the basis of Table 2 (the closest larger value shall be assumed).

3.3 Identification of the Crane Classification Group in General

After identification of the application class in accordance with Table 1 and the loading conditions on the basis of Table 2, the Classification Group of the particular crane may be established utilising Table 3.

4. Gear Classification Groups in General

4.1. Class of Gear Application

The maximum total duration of operation may be obtained on the basis of envisaged daily time of application in hours, the number of working days per year, and the expected service life in years.

In this Classification, it was assumed that the time of gear operation is understood as the time, during which the gear is moving.

The values of total duration of application shall be only viewed as theoretical, conventionally assumed, and serving as initial data to design gear parts, for which application time is the criteria for selection (e.g., ball bearings, toothed gear wheels, and shafts). They cannot be considered as guaranteed values.

4.2. Loading Conditions

Loading conditions determine relative duration, with which gear will be exposed to maximum or lowered loads. Table 5 gives rated loading conditions.

INTERNATIONAL STANDARD ISO 4308/1 (CRANES AND LIFTING UNITS. WIRE CABLE SELECTION. PART 1. GENERAL PROVISIONS).

146

Introduction

This International Standard is a part of ISO 4308 International Standard related to the issue of steel wire cable selection for cranes and lifting equipment.

A complete list of ISO 4308 parts is as follows:

Part 1. General Provisions.Part 2. Self-Propelled Boom Cranes.Part 3. Tower Cranes.Part 4. Portal and Pedestal Cranes.Part 5. Overhead Travelling and Gantry Cranes.

1. Purpose and Scope of Application

This International Standard establishes two methods of wire cable selection for hoisting units, types of which are set forth in ISO 4306/1 and listed in Appendix A.

This Standard establishes minimum requirements for wire ropes that shall have an acceptable margin of stress and operational features accounting for their design, application and maintenance.

The Standard gives the potential to select a wire cable utilising one of the two methods; one of them is based on accounting for the value of the cable selection factor (C), and the other accounts for the value of the utilisation factor (Zp). Table 1 shows the values of the above factors.

Table 1Values of ZP and C Factors (for R0=1570 N/mm2, and K’=0.2948)

Note: Equation (1) gives exact ratio between the C and Zp factors. The values of C and Zp are adjusted and correspond to numbers of the Renard’s series.

For a particular crane type (self-propelled boom, overhead travelling, gantry, etc.), classification groups shall be selected in accordance with ISO 4301/1. Cable selection shall account for values of C and Zp factor s (or their design equivalents) only.

3. Cable Type

A wire cable to be used shall comply with the requirements of ISO 2408.

A steel cable that is not specified in ISO 2408 may be applied; in such cases the Vendor shall confirm to the Customer that the cable complies with the minimum requirements provided by the appropriate section of ISO 4308 Standard.

4. Operating Conditions

Classification of lifting unit gear shall be made accounting for operating conditions specified in ISO 4301/1.

5. Cable Selection Procedure

5.1. Calculation of the cable selection factor (C).

The value of C is a function of Zp, and shall be calculated I accordance with the following equation:

where C is the cable selection factor (minimum); K’ is an empirically determined factor of the minimum breaking load of a particular design cable (see Table 2 of ISO 2408); R0 is the minimum ultimate tensile strength limit of the cable wires, N/mm2;Zp is the minimum actual utilisation factor.

5.2. Values of the utilisation factor (Zp). Table 1 shows values of the Zp factor that shall be applied for each gear classification group to comply with the minimum requirements of the appropriate ISO 4308 Section, and design values of the C factor, which correspond to, e.g., a cable with a particular tensile strength (R0 = 157o N/mm), and empirical factor (K’ = 0.2948).

1 N/mm2 = 106 N/m2 = 1 MPa.

148

For cables with other than stated above ultimate tensile strength limit (R0) and empirical factor (K’), values of the C factor may be calculated utilising equations (1) and (2).

5.3. Calculations of the minimum cable diameter.

The minimum cable diameter (d) in millimetres shall be identified in accordance with the following equation:

where C is the cable selection factor, and S is the maximum cable tension in Newtons, accounting for the following:

a) the rated operating load of the unit;b) the weight of the tacking and/or other lifting device;c) multiplicity of reeving (the polyspast transmission ratio);d) the polyspast efficiency;e) the weight of the hanging portion of the load rope (if the lifted load is

more than 5 metres below the turning gear of the lifting device).

5.4. Estimation of the minimum breaking tension.

The minimum breaking tension shall be identified in accordance with the following equation:

F0 = S x Zp (3)

Examples of a cable selection are given in Appendix B

6. Drum and Block Diameters

The minimum diameter of drums, blocks, and equalising blocks measured along the centreline of a wound cable shall be calculated on the basis of the cable minimum diameter, which is provided by Section 5.3, utilising appropriate values of h1, h2, and h3 factors that depend on the gear classification group (Table 2):

D1 h1d (4), or D2 h2d (5), or D3 h3d (6)

where D1 is the diameter of the drum on the centre line of the wound cable;D2 is the diameter of the block on the centre line of the wound cable;D3 is the diameter of the equalising block on the centre line of the wound cable;D is the minimum diameter of the cable (Section 5.3);h1 is the drum diameter selection factor (the ratio of the drum diameter along the centre line of the wound cable to the design cable diameter);h2 is the block diameter selection factor (the ratio of the block diameter along the centre line of the wound cable to the design cable diameter);

149

h3 is the equalising block diameter selection factor (the ratio of the equalising block diameter along the centre line of the wound cable to the design cable diameter).

Table 2Factors of h1, h2, and h3 Selection

Gear Classification Group

Diameter Selection FactorsDrum (h1) Block (h2) Equalising Block (h3)

For particular cases of hoisting equipment applications, e.g., self-propelled boom cranes, it is recommended that a single line of h factor values should be selected irrespective of the gear classification group.

7. Stationary Cables

Stationary cables are fastened at both ends, and are not used for winding on drums. Such cables are selected in accordance with the requirements of Section 5.4, utilising adjusted values of Zp factor specified in Table 3. The maximum tension of the cable (S) shall be specified by the gear producer, and it shall account for both static forces, and wind and dynamic loads.

8. Hazardous Conditions

In case of operation in hazardous conditions (operations with liquid metal):

a) No classification group below M5 shall be applied;

150

b) When the cable is selected, the value for 25% Zp shall be considered up to the maximum 9.0, or the value of C shall be taken for a higher classification group.

9. Steel Wire Cable Inspection, Maintenance and Rejection

Wire cable inspection, maintenance and rejection standards in accordance with ISO 4309 are recommended for application.

INTERNATIONAL STANDARD ISO 4310 (CRANES, REGULATIONS AND METHODS OF TESTING)

1. Purpose and Scope of Application

This International Standard establishes contents and methods of testing that are required to check whether cranes comply with their specified characteristics, as well as to check their capacity to lift rated loads. If stability determines the value of a rated load, then a testing method and a testing load shall be established, which will allow the stability margin to be easily tested.

This Standard shall be applicable for the following types of cranes:

a) overhead travelling;b) gantry;c) portal;d) self-propelled boom and excavator cranes;e) tower;f) railway;g) cable cranes;h) other types of cranes that may be included into the list additionally.

2. Methods and Scope of Testing

2.1. Three types of testing shall be applied to achieve objectives specified in this International Standard:

a) Testing for a crane compliance with the data specified in its certificate (Section 3.1);

b) External inspection of the crane (Section 3.2); andc) Testing to check if the crane is adequate for operations (Sections 3.4, 3.5,

and 3.6);

2.2. Each crane shall pass the tests, methods of which are stated above. In case of large-scale production, the number of cranes to be tested (Section 2.1) shall be established on a mutual agreement between the Seller and the Buyer

Legal Parties that have executed a contract: the Seller is the Party to supply the crane, and the Buyer is the Party receiving the crane.

153

2.3 Cranes supplied from producing plants ready for operation shall have been tested at the plant prior to their shipment. Cranes that are installed or finally assembled at their operation locations shall be tested at such locations unless otherwise has been provided by agreements between the Seller and the Buyer.

3. Content and Methods of Testing

3.1. Testing for a crane compliance with the data specified in its certificate.

Testing for a crane compliance with the certificate data shall be carried out in accordance with their load characteristics to check the following parameters:

- Weight of the crane (if practical);- Distance from the rotation axis to the stability edge;- Height of the load lifting;- Speed of the load lifting;- Speed of landing;- Speed of the crane locomotion;- Speed of the trolley travelling;- Rotation speed;- Time for radius modification;- Time for telescoping;- Time for one cycle (if required);- Operation of limiting devices;- Operating characteristics of the power drive parameters, e.g., current

intensity in electric engines under conditions of testing loads application.

3.2. Visual inspection.

A visual inspection shall include a check for the crane compliance with the certificate data and/or a check for conditions of all the critical elements, such as:

- gear, electric equipment, safety devices, brakes, control devices, lighting and signalling systems;

- steel structures and their joints, ladders passage ways, cabins and platforms;

- railing;

- the hook or other load gripping device and their suspension parts;

- cables and their fastening locations;

- blocks, axels and details of their fastening, as well as components of the boom suspension system.

154

No disassembling of any assembled parts shall be included into the visual inspection. Visual inspection includes a check of leads for their normal opening in the course of standard operation, e.g., lids of limit switches.

The objective of the visual inspection is to examine and check compliance with all the specified requirements for cranes.

3.3. Testing during operations with loads.

Tests for the crane adequacy for operation include the following:

- Static testing;- Dynamic testing;- Testing for stability (if required).

3.3.1 Static testing.

3.3.1.1. Static tests shall be carried out with the purpose to check the design adequacy of the crane and its assembly units.

Tests shall be considered successful if during their performance no cracks, residual deformation, paint peeling or damage that may influence the crane operability and safety are identified, and no joint retention loss or damage occurs.

3.3.1.2. Static tests shall be also carried out for each load-lifting unit, if it is provided by the crane certificate, at simultaneous operation of load lifting units in positions and design options that shall be selected so that tensions in cables, as well as mending momentums and/or axial forces in the basic crane components were the highest. A testing load shall be gradually increased, lifted to the height of 100-200 mm from the ground surface and held in that position during the time, which is required to carry out the test, but at least 10 minutes.

3.3.1.3. The testing load (P) for all cranes shall be at least 1.25, unless a higher value is required in accordance with National Standards or cable positions.

Components of the P value are as follows:

a) Load on the lifting gear, including the weight of the effective load, as well as the weight of the hook unit and rigging devices (for self-propelled cranes);

b) The rated load-lifting capacity for the equipment established by the producer. The rated load-lifting capacity shall not include any lifting devices being a permanent part of the crane in operating position (for other cranes).

155

3.3.2. Dynamic testing.

3.3.2.1. Dynamic tests shall be carried out with the purpose to inspect operation of the crane gear and brakes.

The crane shall be considered as having successfully passed the test if it is established that the above mentioned components perform their functions, and if further visual inspection reveals no damage to the gear or structural elements, and no joint retention loss occurs.

The crane shall be controlled during the tests in accordance with requirements specified in the crane documentation. Attention shall be paid in the course of the described tests to prevent accelerations and speeds from exceeding the values specified for the crane operation.

3.3.2.2. Dynamic tests shall be carried out for each gear or, if it is provided by the crane certificate, at simultaneous operation of the gear in positions and design options that correspond to the maximum loading of the gear.

Testing shall include a re-start and a stop at each movement within the whole range of such movement, and shall continue for at least 1 hour, while complying with that particular operation cycle.

Testing shall include gear start-up from the intermediate position, with suspended test load. In such case no reverse movement with the test load shall occur.

3.3.2.3. The testing load (P) shall be at least 1.1.

3.3.3. Testing for stability.

3.3.3.1. Tests for stability under load shall be carried out with the purpose to check the crane stability. The crane shall be considered as having successfully passed the test if no tilt of the crane occurs, when a static load is applied to the hook.

3.3.3.2. In case of self-propelled boom cranes, the testing load for stability tests shall be established utilising the following equation:

1.25P +0.1Fi (1)

where Fi (F1 or F2) is the weight of the crane boom (G), or the weight of the gooseneck (g) adjusted to the head of the boom or gooseneck.

If the weight of the boom (G) is small, and the gooseneck is designed for relatively small loads, testing for stability shall not be carried out in accordance with equation (1), with the test load lifted on the gooseneck head.

156

In such case requirements to stability shall be checked by way of calculations.

Note: The value of 1.25P may vary in cases, when higher values are required.

A drawing below shows a side view of a typical crane, with the described parameters identified:

L and l are lengths of the boom and gooseneck (for telescopic booms it is the length of the boom under discussion); X, Y and x, y are coordinates of the boom and gooseneck gravity centres; j and k are radii of the boom and gooseneck; m and n are gravity centre radii for the boom and gooseneck;

Fi shall be calculated in accordance with the following equation:

Designation of Parameters to Estimate Loads for Stability Testing

157

For cranes equipped with a boom only, k=n=g=0, and

For cranes equipped with both a boom and a gooseneck, if the load is lifted on the boom head, k=0, and

if the load is lifted on the gooseneck head,

Note: Values of P, G, g and the centre of gravity coordinates X, Y and x, y shall be established in the crane documents for each value of L and l.

3.3.3.3. No special tests for stability shall be carried out for all cranes, with the exception of self-propelled ones.

3.3.3.4. Tests shall be carried out at such positions and design options within a specified operating area, at which the crane stability is minimum.

If different loads are established for different positions or operating areas, stability testing shall be carried out to select such conditions.

3.4. A Testing Statement.

On completion of testing in accordance with Section 2.1, a Statement shall be drawn out, which shall include conclusions and testing results. The Statement shall state the serial No. of the tested crane, the date and testing location, and the name of Testing Supervisor. Exact loads, positions, design options, methods and testing results shall be also specified for each separate case.

With reference to cranes that comply with the requirements of Clause 2.1 b only, the Statement may be drawn in a shortened form. Such Statement shall contain the crane No., the date and location of testing, the Supervisor’s name and testing results for each parameter.

158

4. Testing Conditions

4.1. To carry out testing, the crane shall be equipped with operating equipment for the rated load in accordance with the crane documentation.

4.2. Cranes travelling along a rail track shall be tested on the track, which shall be constructed and laid in accordance with specifications stated in the crane certificate.

4.3. Air-tyred or caterpillar cranes shall be tested on a horizontal site with hard cover, which will have a deviation from the horizontal line of 0.5%.

4.4. Wind speed during the testing period shall not exceed 8.3 m/sec (30 km/hr). The crane position shall correspond to the mostly favourable conditions (wind speed) unless it is provided by the Contract.

4.5. When air-tyred cranes are tested without outrigger application, pressure in the tyres shall not differ from the pressure set by the producer for more than 3%, and all the wheels shall be oriented along the crane centre line.

Note: Conditions of the overhead travelling crane bridge support shall be agreed with the requirements of the producer.

4.6. If a crane is tested with outriggers, it shall be located with the deviation from the horizontal line not exceeding 0.5%.

4.6.1. If an air-tyred crane is tested with outriggers, it shall be located so that its wheels are not in contact with the ground, and are relieved from the crane weight, unless there are other instructions of the Seller.

INTERNATIONAL STANDARD ISO 88087 (SELF-PROPELLED CRANES. SIZES OF DRUMS AND BLOCKS

1. Purpose and Scope of Application

This International Standard establishes the minimum ratio of the drum and block diameter to the rated diameter of the cable used for lifting and lowering.

159

The rated diameter of a cable is an initial value, which utilisation provides for universality of application, as it is not limited by the crane gear, while self-propelled cranes are designed for various purposes, such as load lifting with a hook, clamshell or electric magnet.

This International Standard shall be applicable to the main types of self-propelled cranes in accordance with ISO 4306/2.

2. References

3. Sizes of Drums and Blocks

The minimum ratio of the drum and block diameter to the rated diameter of a cable is shown in the table below.

Taking into account that self-propelled cranes are often designed for versatile application, only one group of ratios is given.

Thus, the values represented have no dependence on the classification of crane gear.
