Lifting on a higher level

Demag HCW High Capacity Winch Crabs

Compact design and high performance

Demag HCW open winch units feature an extremely compact design. Thanks to their outstanding combination of size and lifting capacity, they can be used to create a full range of solutions for power stations, shipyards and heavy mechanical engineering applications. The load on the crane superstructure can be significantly reduced due to the low hoist unit deadweight.

HCW hoist units are equipped with wear-resistant components and offer good accessibility for service and maintenance. They can also be used to modernise existing crane installations where little space is available. HCW open winch units can be configured to meet individual needs thanks to their modular system design. Fast, safe and reliable – thanks to clearly defined interfaces. And without the need for any additional design or development work.

Precise positioning of heavy loads

Our open winch units offer optimum approach dimensions to utilise the existing floor area. Depending on their design, the 4 or 6-wheel crabs ensure uniform distribution of the load on the crane girders. Loads can be safely and precisely positioned thanks to true-vertical-lift reeving arrangements up to 20/2, optional integrated load-sway reduction and inverter-controlled microspeeds.

Reliable drives

The drives are equipped with high-quality, perfectly matching components to ensure reliable operation in lifting and travel applications.

Double performance

HCW open winch units offer exceptional lifting power. With load capacities up to 500 t, they provide the necessary lift in the upper load capacity range. By using them as tandem units, their lifting capacity can be increased to 1,000 t.
