(a) FIVE maintenance procedures to be carried out on lifting equipment (5 marks)
Regular cleaning and lubrication – Remove dirt, salt, and corrosion; lubricate moving parts such as sheaves, pins, and bearings to ensure smooth operation.
Inspection of wire ropes and chains – Check for broken wires, kinks, corrosion, wear, or elongation; replace if beyond acceptable limits.
Examination of hooks and shackles – Inspect for cracks, distortion, wear at the throat or pin, and ensure safety catches are secure and functional.
Checking of markings and identification – Verify that each item is clearly marked with its Safe Working Load (SWL) and identification number.
Protection from corrosion and damage – Apply protective coatings or grease, store under cover when not in use, and ensure proper stowage to avoid mechanical damage.
(b) Who should carry out the examination, interval between examinations, and typical defects found (5 marks)
Who:
A competent person (qualified inspector, classification society surveyor, or authorised testing organisation) must conduct the thorough examination.
Interval between examinations:
At least every 12 months for fixed lifting appliances (cranes, derricks).
Every 6 months for loose gear, chains, wire slings, and other portable lifting equipment.
After any major repair, modification, or overload, the equipment must be re-examined before use.
Typical defects that may be found:
Cracked or distorted hooks, shackles, or blocks.
Corrosion or pitting on metal components.
Worn sheaves, bearings, or pins causing uneven loading.
Broken wires, fraying, or kinking in wire ropes.
Missing or illegible SWL markings or certificates.
