  1. Lifting Operations & Lifting Equipment

  2. LOLER 98 • Lifting Equipment must be of adequate strength & stability, as must the load itself • Lifting equipment used for lifting people must be designed 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

  3. LOLER 98 • 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 6 months; 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

  4. Cranes • Types: • Tower Crane • Mobile Crane • Derrick Cranes • Gantry Cranes • Overhead Cranes

  5. Cranes • Safety Devices: • SWL/Radius Indicator • Automatic Safe Load Indicator

  6. 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

  7. Platform Hoists • There are 2 main types: • Cantilever type • Enclosed structure type

  8. Lifting Equipment • Jacks • Screw Jacks • Ratchet Jacks • Hydraulic • Winches

  9. Lifting Tackle • Ropes • Block & Tackle • Chains • Eyebolts

  10. 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. 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. 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

  13. 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

  14. 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

  15. Lifting Operations • Site Conditions • Access/egress routes • Inclines/gradients • Location of adjacent buildings • Location of overhead lines • Ground firm enough to support crane and outriggers • No voids exist e.g. manholes, drains etc.

  16. 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

  17. 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

  18. 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

  19. Lifting Operations • Inspection • Cranes must have an examination & test loading every 4 years • A thorough examination is required every 14 months and an inspection and a test of the safe load indicator should be undertaken each week • Inspections must be recorded
