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: l Tower Crane l Mobile Crane l Derrick Cranes l Gantry Cranes l Overhead Cranes
5
Cranes Safety Devices: l SWL/Radius Indicator l 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: l Cantilever type l Enclosed structure type
8
Lifting Equipment Jacks l Screw Jacks l Ratchet Jacks l 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 l Access/egress routes l Inclines/gradients l Location of adjacent buildings l Location of overhead lines l Ground firm enough to support crane and outriggers l No voids exist e.g. manholes, drains etc.
16
Lifting Operations Planning the lift l Correct crane l Space for access, egress and movement l Suitable ground conditions l Crane is level l Underground services are protected l No overhead or side obstructions l Overhead power lines are isolated
17
Lifting Operations Planning the lift l Area around lift is demarcated l Load is within SWL of crane l Location of lifting points ensure load is level l Lifting points are strong enough to take the load l There are no persons under the load AT ANY TIME
18
Lifting Operations Planning the lift l Crane driver is given clear instruction by banksman, either by hand signals or radio l All involved understand their role and are competent to undertake it l All checks on crane and operator documentation are made l Safety helmets are required to be worn by all staff are in vicinity l Competent supervision
19
Lifting Operations Inspection l Cranes must have an examination & test loading every 4 years l A thorough examination is required every 14 months and an inspection and a test of the safe load indicator should be undertaken each week l Inspections must be recorded
