MAXTECH 400-500T Floating Crane Heavy-Lift Barge-Mounted Crane for Offshore & Port Operations
Product Introduction
The MAXTECH 400-500T Floating Crane is a heavy-duty barge-mounted crane designed for the most demanding marine lifting operations. Also known as a floating crane or crane vessel, this powerful machine is mounted on a box-shaped barge and capable of moving on water to perform heavy-lifting operations. It is widely used in ports, offshore engineering, bridge construction, salvage operations, and the installation of offshore platforms and wind turbines.
Engineered for Heavy Lifts
With a lifting capacity ranging from 400 to 500 tonnes, the MAXTECH floating crane handles the heaviest loads with ease — from complete machinery modules and offshore components to large ship sections and bridge structures.
Built for Marine Environments
Constructed with marine-grade steel and protected by a C5-M anti-corrosion coating system, the MAXTECH floating crane is engineered to withstand the harsh conditions of open-sea operations.
Flexible Configuration
The MAXTECH 400-500T floating crane can be configured with both main hoist and auxiliary hoist systems, offering flexibility for different lifting scenarios.
Fully Certified for Global Operations
The 400-500T floating crane can be supplied with classification society certificates from CCS, BV, ABS, NK, LR, and DNV — ensuring compliance with flag state and port state regulations worldwide.
