Deck crane hyd cylinder maintenance

Challenge: The deck crane’s main lift cylinder showed bent rod sections and seal failure, undermining safe lift capacity.
What We Did:

  • Removed the cylinder and straightened the rod to factory tolerances

  • Sent the rod for fresh chrome plating and replaced the full seal kit and wipers

  • Lapped the barrel for perfect rod-to-bore clearance

  • Reassembled, repainted with marine-grade topcoat, and pressure-tested at 120 % working load
    Result: Crane regained full rated capacity, corrosion protection improved, and vessel operations resumed on schedule.
