Overhead, area-serving load transport
KBK single-girder suspension cranes
Safe and reliable transport at high level
Single-girder suspension cranes from our KBK light crane system enable you to achieve fast and reliable area-serving overhead handling and exact positioning of a wide variety of goods. With our optimised and modular KBK components, spatial challenges and requirements are already taken into account during the planning stage.
Reduced approach dimensions and thus improved utilisation of the available space are ensured by our optimised trolleys. During the project engineering phase, planners already gain more flexibility thanks to, for example, larger distances between suspensions and the option of an integrated conductor line, thus reducing installation work and assembly costs.
Useful KBK additional components enable owners of installations to respond to changing requirements at any time. Variable travel path limitation, for example, makes it possible to limit travel motions in just a few steps. Quick and easy to install. What qualities do our KBK single-girder suspension cranes offer?
- Modular system design
- Smooth and reliable handling
- Smooth manual travel
- Cost-effective implementation
- Customer-specific configuration to meet individual requirements
- Reduced approach dimensions
- Larger distances between suspensions
- Lower assembly costs
Steel support superstructure
Cantilever supports for universal applications:
- Support system can also be used wherever workshop ceilings and roof structures cannot bear loads
- High flexibility for planning and configuration
- Particularly easy assembly
Profile sections
- Freedom for planning with a broad range of KBK profile sections to meet differing needs:
- 9 KBK steel profile sections in 6 sizes
- 6 KBK aluminium profile sections in 4 sizes
- KBK profile sections are tough and highly resistant to corrosion and impacts. The KBK system allows different profile sections to be combined in one installation.
Trailing cable
Reliable power supply:
- Highly flexible and cold-resistant flat cables
- Various cable carriers:
- Narrow cable sliders made of tough plastic
- Smooth-running cable trolleys
Integrated conductor line
- Power supply arrangement for suspension monorails also with complex layouts:
- Up to eight conductors integrated in the profile section
- Reliable power supply without any external interference contours
KBK trolleys
Excellent smooth-running performance and minimum rolling resistance over their entire service life:
- Quiet and smooth operation thanks to plastic wheels that are mounted in anti-friction bearings and lubricated for life
- Maintenance-free travel wheels with effective shock absorption
- Compact design with low deadweight
Travel drives
Recommended for use with heavy loads and complex installations:
- Electric and pneumatic variants
- Large friction wheels that have a high friction coefficient ensure reliable transmission of drive torque
- High traction: connection between travel drive and track does not depend on position and weight of the load
- Quiet-running drives
KBK II-H joint connection
Simplified planning and project engineering by the completely rigid rail connections:
- The rail joint can be subjected to a full load –regardless of the position of the track suspension
- No additional steelwork required
- Efficient solution with short delivery times
- Fast track connection assembly thanks to self-retaining nuts (secured against turning)
KBK suspensions
Secure attachment with articulated suspensions
- Significant reduction of horizontal forces in roof and support superstructures
- Impacts and noise minimised by plastic shells in the ball joints
- Exact alignment down to the millimetre thanks to track height adjustment with threaded suspension rods
- Flexible mounting arrangements for connection to various superstructures
- Low maintenance requirement

Product information
The benefits at a glance
Optimum space utilisation
- Overhead, area-serving load transport
- Optimum utilisation of space thanks to minimum approach dimensions
- Suspension from existing workshop ceilings or roof structures
- Require no additional supports for the crane runway
Convenient handling
- Easily moved by hand
- Smooth-running, snag-free operation thanks to articulated connections between the crane girders and trolleys
- Low deadweight
- Customer-specific and cost-effective solutions for workshops – also in limited sections
- Versatile applications thanks to modular system design (e.g. latching arrangements with KBK suspension monorails for crane trolley transfer)
- Cranes can also operate on runways that are not parallel

Demag trolley limit stop
The Demag KBK trolley limit stop improves the modularity of the light crane system: Buffers can be very easily installed at any time, which enables KBK Steel (II-L, II, II-H) and Aluline (18, 22) crane equipment to be buffered along the crane girder or crane runway. A temporary or long-term limit of the long and cross-travel motions can be installed in no time at all. The trolley limit stop is fitted with Demag cellular plastic buffers and can be installed under the rail. The benefit: The noise level in the event of unavoidable collisions can be reduced.
Two variants of the trolley limit stop can be supplied. The difference lies in the time frame for use. Travel along the crane runway or girder can be limited in the long term using the bolted variant. They can be installed at variable positions along the rails.
Demag trolley limit stop with bolt for long-term applications. |
Demag trolley limit stop with lever for temporary installation. |
The variant with a lever is also suitable for variable installation, but it can be released and repositioned more quickly and easily thanks to the lever. Temporary limit stops for the long and cross-travel motions can be easily installed in this way. For example, this may be needed to close the end of a track, to fix a crane or trolley in position or to secure the crane for installation or service work.
