Variable overhang for inaccessible areas

KBK extending cranes

Large overhang – constant or variable

Loads can be moved beyond the crane runway using overhung and extending cranes from our KBK modular 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 over 8ft (2.5m) beyond the runway span

Product information

The benefits at a glance

KBK overhung cranes

  • Efficient utilisation of the workshop (e.g. workshop areas added at a later date can also be served without the need to install an additional crane runway)
  • They can be operated beneath ventilation ducts, radiant heaters and cables 

KBK extending cranes

  • Depending on the design, girders can be extended to one or both sides beyond the width of the crane runway
  • They can also be used for precisely lifting and positioning loads in almost inaccessible areas (e.g. between pillars and columns)
