ITEMS TO ADDRESS WHEN PLANNING LIFT (check all highlighted in yellow prior to lift) YES N/A
Has the responsible manager and the Safeguards & Security Division been notified of movement of the load to the lifting site
Has the load transport route to the lift site been checked for overhead obstructions? Are there any bridges, culverts, pipe ways to cross? Are they structurally capable of safely supporting the transport loads?
Are the minimum actual clearance between the load and the boom during the lift within allowed limits? √
Has the radius been double-checked by measuring in the field?
Will spreaders and other rigging hardware remain safely clear of the boom, the load, and other objects at all times during the lifting operation? √
Have obstructions been identified in the lift path and swing path?
Can the outriggers be deployed as per manufacturer’s load chart requirements? √
Can rigging personnel safely control and manipulate the load throughout the lifting path? √
Are the crane’s operational safety alarms functioning properly?
Has a drawing showing the elevation of the crane during the lift as well as all clearances been developed (boom to load, and load to other obstructions)?
√
Have all repairs or modifications to the crane been made in accordance with manufacturer’s written instructions, and are they so certified?
Has the agreed nondestructive examination (NDE) of crane components been done and documented?
Is the correct crane load chart for current lift conditions in the cab?
Is there adequate headroom to ensure that the manufacturer’s minimum allowable two-block distance is maintained for the configuration of the reeve used?
√
How was the weight determined when developing the lift plan? Has any contingency been added to calculated weights? √
Has an accurate load weight determination been made before the lift to confirm calculated weight? √

ITEMS TO ADDRESS WHEN PLANNING LIFT (check all highlighted in yellow prior to lift) YES N/A
How was Center of Gravity determined? Is it marked on the load? Is it shown on the lift plan drawings? √
Has the liquid/semi solid inside the load that could shift during the lift been considered?
Is the surface area large enough to create unusual control problems in the wind?
If lifting a dressed device, has the insulation absorbed any water, has this been incorporated in load manifest? √
Have all anchor bolts and fasteners been removed?
Has all rigging hardware been selected to work within the manufacturer’s Safe Working Load? √
Have sling angles flatter than 45 degrees been avoided? √
Have softeners been used to protect the rigging where sharp corners could cause damage? √
Are shackles, pad eyes, eyebolts and hooks always used in such a manner as to avoid side bending in the hardware? √
Is there a plan for removing lifting tackle from the load after it is erected? √
Have all lifting appliances and accessories been inspected before use by a competent personnel ?
Are the shackle pins and lifting eyes compatibly sized? √
Is the rigging arranged to have the crane hook directly over the load’s center of gravity with the load hanging level? √
Has the lift plan been reviewed with the crane operator, riggers, and others involved in the lifting operation?
Has the wind speed been measured by anemometer? Is the wind speed within acceptable limits?
Is adequate lighting equipment available for use √
Have emergency procedures been determined and communicated to all personnel involved in the lifting operation?
Is the load fragile enough to require lifting from a “strong back” frame or from multiple attachment points to prevent load damage? √
Has any required nondestructive testing been done to assess the quality of welds attaching lifting lugs, pad eyes, trunnions, etc.?
Is there enough clearance between the load and the lifting lug/pad eye to get the nut on the shackle pin?
Is there enough clearance between wire rope slings and equipment present on load skid?

Sample Calculation:
Weight of Load = 18000 kgDistance M = 12.5 ft Reaction R1 = ?Distance N = 18 ft m Reaction R2 = ?
We know that Moment = Force X distanceAnd , clockwise moment = anti clock wise momentAnd, Upward Force = Downward Forces
Taking moment at R1 ;Clockwise moment = anti clockwise momentW X M = R2 X (M+N)R2 = (W X M) / (M+N)R2 = ( 18000 X 12.5 ) / ( 30.5 )R2 = 7377 kgs (Reaction at Point B)Upward forces = Downward forcesW = R1 + R2R1= W – R2 = 18000 – 7377 = 10622.9 kgs (Reaction at point A)

Lifting plan & Rigging Study- Amine Reboiler E-1270Sling Tension at Point A (Web sling basket at 90 degree)
Total length of Web Sling Required for a 90 deg Basket Hitch =
15 ft +4.5 ft+4.5 ft = 24 ft
Reaction at point A is 10622.9 kgs
Sin 70 = R1/T1
T1= 10622.9/sin70
T1= 11304.5
Since it is a 90 deg Basket hitch
The mode factor will be 1.4
So the Sling required at point A
Should be atleast 11304.5/1.4 =
8074 kgs
Therefore a 10 tonne, 25 ft long
websling will be adequate to safely lift the Amine Reboiler.
There is no need to calculate the websling tension at point B as the share load is already 7377 kgs which is less than what we calculated above
