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 manoeuvre – and facilitate optimum utilisation 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

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)
