Inspection and Diagnostics:

• Conduct regular inspections of mechanical components (hoist, trolleys, boom, gantry) to identify wear, corrosion, misalignment, and fatigue.
• Use visual inspection techniques and methods to detect internal defects in load- bearing structures and critical components.
• Employ vibration analysis, thermography, and oil analysis to diagnose the condition of moving parts and bearings.

Component Replacement and adjustment:

• Replace worn- out parts such as cables, wire ropes, sheaves, bearings, gears, brakes, and hydraulics components.
• Adjust tension in cables and wire ropes, align mechanical linkages, and calibrate hoisting mechanisms for precise operations,

Hydraulic and Pneumatic System Maintenance:

• Inspect and service hydraulic cylinder, pumps, valves, and hoses for leaks, pressure loss, or wear.
• Ensure pneumatic system are functioning correctly, checking for air leaks or blockages that might reduce efficiency.

Hoist and Gantry motor Maintenance:

• Service electric and hydraulic motors, inspecting for electrical insulation failure, bearing wear, and rotor imbalance.
• Conduct testing on motor windings, insulation resistance, and current ;oads to ensure optimal performance.
• Typical repair services include.

Structural Repairs:

• Repairs cracks or deformities in the crane’s load – bearing structure, including the boom, gantry, and trolley frames.
• Reinforce weakened joints through welding or replacement of worn sections with new materials.

Mechanical Repairs:

• Overhaul or replace defective hoisting mechanisms, such as winches, wire ropes, or sheave blocks.
• Repair or replace malfunctioning gearboxes, drives, and bearing assemblies.

Brake and safety Mechanisms Repair:

• Service or replace faulty braking system (disc, drum, or electromagnetic brakes) to ensure safe crane operation.
• Repair limit switches, sensors, and full-safe devices to restore compliance with safem regulations.

Lubrication of Wire Ropes and Cables:

• Apply specialised lubricants to wire ropes to reduce friction and prevent corrosion from saltwater exposure.
• Inspect for kinks, wear, or corrosion during lubrication routines.

Bearing and Gear Lubrication:

• Apply grease or oil to bearing, gears and shafts to ensure smooth movement and to prevent overheating and metal-to-metal contact.
• Monitor grease condition and quantity, replenishing it to the recommended levels.

Lubrication of Hydraulic System:

• Ensure hydraulic system are properly lubricated to minimise wear on pistons, seals, and valves.
• Replace or top up hydraulic fluids to maintain system pressure and performance.

Guide Rail and Wheel Assemblies:

• Lubricate guide rails and wheels assemblies to prevent jamming or excessive wear from friction during crane movement along its gantry.
