RU and CF push-travel trolleys
Smooth travel, low travel resistance
Trolleys for DC chain hoists
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
