Liebherr BOS 4200 Board offshore cranes

An outreach of up to 72 metres and a maximum lifting capacity of 125 tonnes make the BOS 4200 one of the most powerful and flexible machines for supplying oil and gas platforms and also for maintenance work.

A-frame

The ergonomic and comfortable features of our cabs increase concentration levels. With the integrated noise protection, windshield wiper and air conditioning, a consistently high level of safety and productivity is guaranteed.

Lattice tubular boom

The basic elements of the lattice tubular boom include the boom foot with the main and auxiliary hoisting winches, as well as the head with optional auxiliary hoist and hook block. Owing to the different lengths of the boom, the cranes can also be individually adapted to your requirements.

Pedestal adapter

As an interface for customer installation, the basic pillar adapter fulfils various functions. It controls the positioning of the slip ring assembly and guarantees the precision fit of the large diameter bearing.

Hydrostatic drive

Closed hydraulic loops are used for all main functions such as lifting, turning and luffing. The crane operator benefits from extremely precise control, the service personnel benefit from a minimum number of components and the operating company benefits from reduced fuel consumption.

Paintwork

To be able to defy offshore environmental conditions, the standard paintwork consists of multilayer painting for optimal conservation.

Litronic crane control system

The control system developed by Liebherr focuses on precision, safety and productivity.

Machine housing

The machine housing is made from robust steel components. All components such as the drive unit, oil tank and control cabinets inside the machine housing are easily accessible. If required, they can be lifted on deck with the assembly crane.

Assembly crane, machine housing and A-frame

For the assembly / disassembly of components for maintenance and repair.

Overload monitoring system

Enables the crane operator to release the rope in case the hook is entangled. The overload monitoring system can be activated either manually or automatically.
