We manufacture single-girder underslung cranes up to 25 000 kg. They are suitable for workplaces without consoles for overhead crane railway or for workplaces without the possibility to build independently staying crane railway. The condition for underslung bridge crane installation is already existing ceiling construction fixed enough for hanging or anchoring the underslung crane railway.



Among the advantages there is costs saving because you needn´t to build a new supporting construction for crane railway. Another advantage is the possibility to use side overhangs because it lengthens a running range of a hoist. On the other hand, the disadvantage is the limitation by load bearing capacity of an already existing construction and by the way of anchoring.

Crane setting outside and inside






  • Each crane is projected to measure according to customer´s requirements to be adapted to a place and shed´s conditions (or to open space) and still work effectively
  • Lay out of crane weight into two end carriages guarantees safe handling with very heavy load
  • Economically favourable solution
  • The possibility to use side overhangs
  • Remote control
  • The possibility to place the crane both inside and outside
  • Safety hooks prevent the load from sliding
  • They make the work with a burden easy and effective









 Accessories and Options

  • In case of remote control, the crane could be equipped with emergency control via the hanging button-controller which could move along the whole crane independently of crab trolley drive or it could be connected to the main switchboard of the crane via connector
  • Crane is equipped with two hoists working either independently or in tandem (at the same time) using just one controller
  • Weighing of transported load with an output to a crane display, to a controller display or to PC
  • Anti-collisional systems in case of several cranes being on one railway
  • Automatic control system
  • Version with a slewing beam, with a grab or with a magnet
  • Colour of cranes according to customer´s requirements
  • Modification for use in potentially explosive atmospheres
