BOS 4200

Drive variants for operating the hydraulic system of the crane with integrated start-up system for limiting the starting current values.

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.

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.

Operation without a loss of productivity is also possible when it is dark. Powerful LEDs and fluorescent lamps at the boom, slewing platform and the machine housing provide optimal lighting of the work environment and for inspecting the crane.

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

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.

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.

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

The slewing platform is the basic element of the crane. In addition to the machine housing, it also houses the cab, the A-frame, as well as luffing winch.
