Underslung Bridge Cranes Púchov

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.

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
