GENMA Marine Cranes Featured on Chinese National Media for New-Generation Deepwater Vessel

China’s state media recently reported the completion and delivery of “HYSY 292” – a new-generation deepwater multipurpose offshore engineering vessel built in Jiangsu, China. The vessel is equipped with GENMA‑branded 400‑ton marine crane and 50‑ton knuckle boom crane, both manufactured by Nantong Rainbow Heavy Machineries Co., Ltd.

The report highlighted the vessel’s coordinated twin-crane and intelligent lifting system, which enables the 400-ton main crane and the 50-ton auxiliary crane to work in tandem. Controlled by an intelligent lifting control system, the two cranes deliver precise coordination for diverse and complex offshore operations.

GENMA 400T Pedestal-Mounted Crane – Heavy-Lifting Core for Deepwater Operations

The 400-ton crane is custom-engineered to match the vessel’s hull structure and working space for optimal load curves. Key components are enclosed within the tower to resist corrosion in the harsh marine environment, extending service life.

Powered by AFE full-frequency drive technology, the crane delivers smooth, precise control even under heavy loads. Safety features include load moment limiting, emergency release, and overspeed protection for both personnel and equipment safety. Its low-center-of-gravity design ensures compact structure and strong seakeeping ability in rough sea conditions. The modular design simplifies transport and on-site assembly, reducing vessel conversion time.

GENMA 50T Knuckle Boom Crane – A Flexible and Efficient Deck Assistant

The 50-ton knuckle boom crane features an articulating folding arm that saves deck space when not in operation. The welded box-type boom is lightweight yet rigid, with a low center of gravity for excellent stability.

Its four main functions – hoisting, luffing, slewing, and knuckle folding – can operate independently or in unison with fully variable speed control, delivering smooth, impact-free motion with high energy efficiency and precision. The simple, low-maintenance design includes an integrated hydraulic power unit for flexible adaptation to different power environments.

GENMA remains committed to driving innovation and service excellence, standing by every piece of equipment as it ventures into deep waters – delivering reliable support for every lifting operation.
