Smooth travel, low travel resistance

Trolleys for DC chain hoists

RU and CF push-travel trolleys

Demag trolleys perfectly complement DC chain hoists and are easily installed on I-beam girders or a KBK modular crane system. For push travel or with electric positioning, our trolleys provide horizontal travel solutions tailored to meet our chain hoist needs.

  • 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 height utilization
  • Double chain hoist for mechanically synchronized lifting, e.g. for long material or large-volume components

The benefits at a glance

Click-fit trolleys

  • Simple click-fit installation
  • Articulated trolleys (minimum curve radius: 31.5 in (800 mm))
  • Easily adaptable to standard-profile or parallel-flange sections
  • High safety and reliability thanks to integrated drop-stop and lift-off protection
  • Universal solutions for loads up to 1,200 lbs (550 kg)
  • Flange widths from 1.06 to 3.58 in (50 to 91 mm)

U/RU push-travel trolleys

  • Excellent travel characteristics
  • Fast and simple installation
  • Can be used on parallel and sloping flanges
  • Smooth travel, low travel resistance
  • Negotiate curves down to a minimum radius of 39.4 in (1,000 mm)
  • Drop stop integrated into the side cheek
  • Extremely low girder wear
  • Designs with polyamide or steel rollers
  • Compact, state-of-the-art industrial design
  • Four sizes: U 11 up to 2,400 lbs (1,100 kg),
    • U 22 up to 4,800 lbs (2,200 kg),
    • U 34 up to 7,500 lbs (3,.400 kg),
    • RU 56 up to 12,000 lbs (5,600 kg)

E 11 to E 34 electric travel drives

  • Smooth starting and braking
  • Low-sway load handling
  • Fast installation and commissioning
  • Designed for operation with DC-Pro chain hoists
  • Control via DSE 10-C/DSE 10-CS control pendants
  • Fast availability thanks to plug-&-drive: plug-in connection to DC-Pro chain hoists
  • Simple installation of the control pendant for long/cross travel
  • Optional: cross-type limit switches for fast-to-slow and final limit-switch cut-off

KBK trolleys

  • E 22 fitted as standard with RF 125 friction-wheel travel drive for use with KBK modular crane system
  • Short approach dimensions for vertical mounting arrangement

Low-headroom hoist

  • Load capacity up to 4,400 lbs (2,000 kg)
  • Optimized design for maximum utilization of the available height
  • Can be used for all trolley types

Double chain hoist

  • Load capacity up to 5,500 lbs (2,500 kg)
  • Hook center distances from 21.5 in to 126 in (550 mm to 3,200 mm)
  • Possible designs: stationary, traveling, for operation with KBK and for articulated trolleys
  • Reduced polygon effect and longer chain hoist service life since no additional chain return sprockets are needed
  • Suitable for higher speeds
  • Asymmetric load distribution permitted
