Title: Lifting Operations & Lifting Appliances


1
Lifting Operations Lifting Appliances
2
LOLER 98
  • Lifting appliances must be of adequate strength
    stability, as must the load itself
  • Lifting appliances 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 Appliances
  • Jacks
  • Screw Jacks
  • Ratchet Jacks
  • Hydraulic
  • Winches

9
Lifting Accessories
  • 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 Accessories
  • 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
Accessories
  • 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
Accessories
  • 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
    slinger/signaler, 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 12
    months and an inspection and a test of the safe
    load indicator should be undertaken each week
  • Inspections must be recorded
