Lifting Reliability
Mechanical, Hydraulic & StructuralMarine & Offshore Crane Support
Safe, Reliable, and Certified Deck Crane Operation
We provide comprehensive deck crane repair, maintenance, and troubleshooting services for ships, Coast Guard vessels, offshore vessels, and marine equipment.
Our services are focused on ensuring safe, reliable, and efficient crane operation under demanding marine conditions. Operating at sea subjects deck cranes to intense corrosion, dynamic wave-induced stress, and continuous heavy loading.
Whether your vessel requires immediate voyage troubleshooting for hydraulic failures, planned dry docking overhaul of slew rings and gearboxes, structural boom repairs, wire rope changeouts, or certified load testing, Luhar Kalidas provides rapid-response technical expertise.
Our multi-disciplinary technicians handle mechanical drives, hydraulic power systems, structural steel renewal, and electrical safety interlocks to ensure complete regulatory compliance.
