Crane Hoisting & Luffing Pump Gearbox Seal Renewal – Abu Dhabi

At Blue Gulf Port, Abu Dhabi, a critical maintenance operation was successfully carried out on the crane’s hydraulic drive system.

Scope Of Work

• Dismantling of hoisting & luffing pump assembly
• Inspection of splitter gearbox internal components
• Seal removal and precision surface cleaning
• Renewal of worn oil seals and sealing interfaces
• Technical Observations
• Signs of oil leakage due to seal wear and ageing
• Gear and spline condition verified — no abnormal wear
• Bearing seating and mating surfaces checked for integrity
• Execution Highlights
• Controlled dismantling to avoid shaft/spline damage
• Proper alignment during reassembly
• Seal installation with correct tolerances and lubrication
• Pressure verification carried out post-installation

Outcome

• Leakage eliminated
• Restored hydraulic efficiency
• Improved system reliability under load conditions

In heavy-duty crane operations, small seal failures can lead to major performance losses — timely intervention ensures operational continuity and safety.
