Heavy-duty articulated boom(IB)marine cranes are available in different capacities ranging from 8 to 400 tm. This kind cranes are custom built according to requested load,radius and sea state.
As a result of their sophisticated crane geometry work is effortless with articulated boom cranes. They make full use of their strengths and flexibility when loading and unloading equipment. Due to their compact construction they can easily be accommodated on every type of vessel especially where space is limited. Adding various features and options make the articulated boom marine crane a multi-functional tool. YFM articulated boom cranes can be designed according to offshore rules and regulations.
