Trolleys for DC chain hoists

Smooth travel, low travel resistance

Trolleys for DC chain hoists

Demag trolleys for chain hoists are a perfect match for DC chain hoists and ideal for installation on I-beam girders or on the modular KBK light crane system. For push travel or with electric positioning – these trolleys provide horizontal travel solutions tailored to meet specific requirements for our compact hoist units.

All trolleys feature a low rolling resistance and smooth travel characteristics over their entire service life. The robust components are perfectly matched and can provide convenient transport solutions for your application needs.

Demag trolleys – the choice is yours:

U type trolleys for manual travel
E type trolleys for low-sway electric travel
Click-fit trolleys that can be clicked into position
Smooth-running KBK trolleys as system components
Low-headroom travelling hoists for optimum utilisation of the available height
Double chain hoist for mechanically synchronised lifting, e.g. for long material or large-volume components
