The crane girders are of welded girder construction. This result in lower dead weights with a high degree of vertical and horizontal rigidity and smaller wheel loads being transmitted to the crane runway.

 

The crane that we are offering is designed to meet the required functions and requirement stated in your specifications, as well as for the operating conditions.

The sub-assemblies used by are standardized equipment of renowned manufactures and have been approved for specific crane operation by our test laboratory. Their characteristics regarding impact/vibrations, wear and safety were examined. A continuous high quality standard is ensured by series production and standardized sub-assemblies.

The electrical equipment is accommodated in robust steel plate control cubicles, on the crane girder.

All movements can be switched off by actuating the emergency-off switch at the control station via a main contactor.

The entire equipment is easy to install and dismantle due to the use of threaded bolts and top-hat rails

Cable inlet from cable gland

Power supply cable and control cable along the girder

A protective earth conductor is fitted as standard. A crane switch is provided.

Travel end switches

Long and cross travel limited by means of preliminary and final limit switches

Overload protection: In the event of overload, the hoist unit switches off and only the lowering motion is possible.
