What We should Check???Lifting & Supporting FPE Audits


Is the trained people available for Lifting and rigging (If any equipment available)

Training


Wire Ropes• Test Certificate (Within One Year)

• Storing method (Away from water or any other contamination which can damage / Stored as it avoid any bents in the rope

• Ropes should be lubricated (Its not compulsory, but better for its reliability)

• Damages / sever bents / loosen up plies


Weather the rope use according to its strength (Use the Chart and the following calculation)

Wire Ropes


Example - Maximum Safe Mass for a 3/8" Wire Rope

The relationship between mass and force (weight) can be expressed as

m = F / g (1)

where

F = force, weight (N)m = mass (kg)g = acceleration of gravity (9.81 m/s2)

Maximum safe mass for a 3/8" wire rope where safe load is 10.9 kN can be calculated as

m= (10.9 103 N) / (9.81 m/s2) = 1111 kg

Wire RopesCheck the correct arrangement of Bulldog grips (in cranes too)


• Storing method (Avoid any damage; best way is roll it and kept in a cupboard without any load on it or hang vertically)

• Any inspection record (To make sure they inspect it)• Check for any physical damage (if any damage available disqualify the sling)• Check for the label with its basic capacities and it should comply with at least one

international standard)• Partly damage means we cant use it even for partial load• If you cant see (inspect) the sling due to debris, consider it is disqualified• Size does not indicate the load capacity

Slings


All hooks must contain a latchCheck the gap at hook throat (If the gap too much latch will come out of the hook)

Hooks


• Test Certificate

• Area of usage (Suitability for the ground condition and overhead structures)

• Operator Competency (NVQ or higher)

• Hook latches

• Lights

• Availability of the load chart

Cranes


Cranes


Anchor Points• Visual inspection for

any deformation

• Test certificate


ARE NOT Anchor Points

• Standard Guardrails• Standard Railings• Ladders/Rungs• Scaffolding• Light fixtures• Conduit or Plumbing• Ductwork or Pipe Vents• Wiring Harnesses• Vents• Fans• Roof Stacks.
