Demag’s high capacity winch cranes
August 2018
Maintenance, Test & Measurement, Calibration
Demag’s compact high capacity winches can handle loads of up to 500 T. With its outstanding combination of size and lifting capacity, the HCW creates a full range of solutions for power stations, shipyards and heavy mechanical engineering applications.
By using them as tandem units, their lifting capacity can be increased to 1000 T. HCW open winch units can be configured to meet customers’ needs thanks to their modular system design, without the need for any additional design or development work.
The load on the crane superstructure can be significantly reduced due to the low hoist unit dead weight. HCW hoist units are equipped with wear-resistant components, ideal for harsh African environments, and offer good accessibility for service and maintenance. They can also be used to modernise existing crane installations where little space is available.
The winch units are ultra-reliable and 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.
Many additional options are available according to customer needs, such as single or double hooks, a motor-driven design and a hook position that can be locked at increments of 90°.

Microdieseling – the explosions you never hear
Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.
