Trolleys for DC chain hoists

Further information

The benefits at a glance

Click-fit trolleys

• Simple click-fit installation
• Articulated trolleys (minimum curve radius: 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 550 kg
• Flange widths from 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 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 1,100 kg, U 22 up to 2,200 kg, U 34 up to 3,.400 kg, RU 56 up to 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 accessory: 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 light crane system
• Particularly short approach dimensions for vertical mounting arrangement

Low-headroom hoist

• Load capacity up to 2,000 kg
• Optimised design for maximum utilisation of the available height
• Can be used for all trolley types

Double chain hoist

• Load capacity up to 2,500 kg
• Hook centre distances from 550 mm to 3,200 mm
• Possible designs: stationary, travelling, 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
• Also suitable for higher speeds
• Asymmetric load distribution permitted
