Variable overhang for inaccessible areas
KBK extending cranes
Large overhang – constant or variable
Loads can also be moved beyond the crane runway using overhung and extending cranes from our KBK light crane system. These solutions offer greater room to maneuver – and facilitate optimum utilization of the available space.
Our solutions to meet specific requirements include:
- Overhung cranes which are fitted with crane girders that extend beyond the width of the crane runway
- Extending cranes that consist of a fixed section and a crane section that can extend in both directions
- Crane girders that extend up to 2,500 mm beyond the runway span
KBK Ergo trolleys
Optimum travel characteristics and high positioning accuracy also at high operating speeds
- Quiet and smooth operation thanks to plastic wheels that are mounted in anti-friction bearings and lubricated for life
- Smooth travel thanks to lateral guide rollers fitted as standard
- Counter-pressure roller to accommodate kick-up forces, can be adjusted via eccentric fitting
- Universal bolted connection to attach customer-specific handling solutions
Profile sections
Freedom for planning with KBK Aluline profile sections
- 6 KBK aluminium profile sections in 4 sizes
- of which 2 sizes with internal conductor lines
- Load capacity up to 2 t
- KBK profile sections are tough and highly resistant to corrosion and impacts.
- Different profile sections can be combined within one installation
- Aluminium and steel can be combined
KBK Ergo suspensions
Safely accommodate kick-up forces
- Rigid design to transfer forces to the superstructure via rubber damping elements
- Height adjustment with millimetre precision
- Ideally suited for applications with manipulators, lifting axes, extending cranes or offset loads
- Further suspensions in the KBK modular system
KBK crane end carriages
Special end carriage design offering high system rigidity
- Very smooth operation with low travel resistance
- High positioning accuracy
- Light-weight design
- Optimum load distribution
- Equipped with Ergo trolleys
KBK Ergo end caps
Easily installed track end cap
- Precise damping elements for every application:
- rubber or cellular plastic buffers and shock absorbers
- Optional power supply via the end caps
Integrated conductor line
Safe and space-saving power supply
- Reliable power supply and transfer of control signals
- More scope due to reduced approach dimensions of the cranes
- Additional headroom gain, as no cable sag
- No risk of collisions (e.g. with forklifts) thanks to lack of cables
- Several cranes can be installed on one crane runway
Overhang and extension function
Extended working area beyond the span dimension
- KBK overhung cranes
- Load handling and positioning beyond the crane runway
- Can also be used beneath ventilation ducts, radiant heaters, cables and pipes
- KBK extending cranes
- Girders can be extended on one or both sides beyond the width of the crane runway
- Loads can be positioned even in almost inaccessible areas (e.g. between pillars and columns)
