Smooth travel, low travel resistance

Trolleys for DC chain hoists

RU and CF push-travel trolleys

Our trolleys for chain hoists are a perfect match for DC chain hoists and ideal for installation on I-beam girders or on our 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. What possibilities do they offer?

  • 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 trolleys for optimum utilisation of the available height
  • Double chain hoist for mechanically synchronised lifting, e.g. for long material or large-volume components
