A Frame Crane is a specialized lifting and handling structure designed for safe and efficient deployment, recovery, and handling of heavy equipment in offshore and marine environments. It is widely used on offshore support vessels, research vessels, subsea construction vessels, and offshore platforms for launching and retrieving subsea tools, ROVs, cables, pipelines, and other underwater equipment.
The A-frame structure consists of two robust side frames connected by a cross beam, forming a rigid and stable lifting system capable of handling high dynamic loads. Mounted at the stern or side of a vessel, the A-frame allows controlled overboarding and inboarding operations while maintaining excellent load stability and operational safety.
Offshore A-frame cranes are powered by hydraulic or electro-hydraulic systems and are engineered for smooth and precise lifting, luffing, and slewing movements where applicable. Advanced control systems enable accurate positioning, while integrated safety features such as load monitoring systems, overload protection, emergency stop functions, and fail-safe brakes ensure safe operation under varying sea states.
Designed for harsh offshore conditions, A-frame cranes are manufactured from high-strength structural steel and protected with offshore-grade corrosion-resistant coatings. Optional features such as active or passive heave compensation, shock-absorbing systems, remote control operation, and redundancy configurations further enhance performance during subsea handling operations.
Offshore A-frame cranes are designed and manufactured in compliance with DNV, ABS, LR, BV, API, FEM, ISO, and CE directives, ensuring full conformity with international offshore safety and performance standards.
A frame crane is designed and produced SWL 100 tons.
