A powerful rotation system with a slewing bearing and gearboxes enables precise work and a better distribution of loads on the base. This slew solution provides the best rotation method for the operator. All gearboxes are supplied with a negative brake that restricts crane movements during operations and boat movements.

The rotation system can be also supplied with special valves for motion control for special applications.

The surface of all cranes are made of a special marine treatment using blasting, high pressure washing and cold galvanizing. An intermediate coat and two layers of polyurethane paint are applied, with a minimum thickness of 340 micron of protection.

On all cranes we can supply a customized procedure, based on the customer’s requirements.

IRON FIST only high strength steels in the construction of our cranes, eg WELDOX. This type of steel ensures the strength of the structure and allows more constructive solutions.

All steels, as well as being certified by suppliers, are also certified and tested in our laboratory . All components are welded by our internal welders, who are dully certified from the major class certification societies.

All components that are not structurally related (eg, support ladders) are fully produced in stainless steel AISI316.

The design is the key start point in the development of the system. It determines the form, structure and function of all IRON FIST products.

The company uses sophisticated software that allows the simulation of the working condition, which enables the design team to de-risk the structure digitally. All our cranes are fully designed for marine applications and for marine environment.
