    LOLER 98

    Lifting Equipment must be of adequate strength &

    stability, as must the load itself

    Lifting equipment used for lifting people must bedesigned to prevent falls, crushing, trapping or

    striking

    Equipment must be positioned and installed to

    prevent load drifting, free-falling or unintentional

    release from causing injury

    SWL and other necessary safe use information

    marked on the equipment

    Lifting operations must be properly planned,organised, supervised and carried out safely

    Equipment must be thoroughly examined after

    installation and prior to service. Equipment for

    lifting people must be examined and tested every 6months; other equipment every 12 months

    Any defects must be reported to employer, with

    particulars as specified in Schedule 1 to the Regs.If defects are found, equipment must not be used

    until they are remedied

    Records must be kept

    Cranes

    Types:

    Tower Crane

    Mobile Crane

    Derrick Cranes

    Gantry Cranes

    Overhead Cranes

    Cranes

    Safety Devices:

    SWL/Radius Indicator

    Automatic Safe Load Indicator

  • 8/12/2019 Lifting Operations 2

    6/19

    Factors to Consider when

    Selecting a Crane

    Weight & dimension of loads

    Height of lifts and distances/areas of

    movement of loads

    Number and frequency of lifts

    Duration of operations

    Site ground conditions

    Space available for crane access, erection,

    operation & dismantling

    Platform Hoists

    There are 2 main types:

    Cantilever type

    Enclosed structure type

    Lifting Equipment

    Jacks

    Screw Jacks

    Ratchet Jacks

    Hydraulic

    Winches

    Lifting Tackle

    Ropes

    Block & Tackle

    Chains

    Eyebolts

    10/19

    Safe Use of Ropes & Wires

    Must be in good condition before use I.e.

    not frayed or corroded

    Ropes & wires must be protected from

    sharp edges of load by use of packing

    No knots or hitches in slings or lifting

    ropes

    Never drag ropes or wires over the ground

    When using more than one sling, ensure

    they are of the same material

    11/19

    Safe Use of Chains

    Never use chains with links locked or

    stretched

    Never hammer distorted links into position

    Never use corroded or worn chains

    Do not drag a chain from under a load

    Do not drop chains from height

    Do not use a chain over sharp corners

    without padding

    Chain life is increased by lubrication

    12/19

    Safe Use of Lifting Tackle

    Never use hooks if there is any distortion or

    cracks

    Rings and shackles must be checked to see

    they are not distorted or cracked

    Storage of Ropes, Wires, Chains

    & Lifting Tackle

    Trained and competent stores

    Stores must be dry, well ventilated and free

    from corrosion

    Ropes must be stored away from sunlight

    and heaters

    Stored material should have a systematic

    layout

  • 8/12/2019 Lifting Operations 2

    14/19

    Storage of Ropes, Wires, Chains

    & Lifting Tackle

    Store should have area where simple

    maintenance can be carried out

    Store should be secure

    An are where paperwork can be carried out

    should be provided

    Lifting Operations

    Site Conditions

    Access/egress routes

    Inclines/gradients

    Location of adjacent buildings

    Location of overhead lines

    Ground firm enough to support crane andoutriggers

    No voids exist e.g. manholes, drains etc.

  • 8/12/2019 Lifting Operations 2

    16/19

    Lifting Operations

    Planning the lift

    Correct crane

    Space for access, egress and movement

    Suitable ground conditions

    Crane is level

    Underground services are protected

    No overhead or side obstructions

    Overhead power lines are isolated

  • 8/12/2019 Lifting Operations 2

    17/19

    Lifting Operations

    Planning the lift

    Area around lift is demarcated

    Load is within SWL of crane

    Location of lifting points ensure load is level

    Lifting points are strong enough to take the

    load

    There are no persons under the load AT ANY

    TIME

  • 8/12/2019 Lifting Operations 2

    18/19

    Lifting Operations

    Planning the lift

    Crane driver is given clear instruction by

    banksman, either by hand signals or radio

    All involved understand their role and are

    competent to undertake it

    All checks on crane and operator

    documentation are made Safety helmets are required to be worn by all

    staff are in vicinity

    Competent supervision
