Single girder gantry crane

Remote control.

Pendent wire

Control method:

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

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

Travel end switches

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

Power supply cable and control cable along the girder

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

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

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 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.

Electrical elements

Average thickness : about 100 microns

After manufacturing (after welding)

In factory before manufacturing :

Painting:

The crane girder and bracket legs 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.

Crane girder and bracket legs:

Rubber buffers

Motor for hoisting and travelling

Hook with latch

Main lifting motor with thermal protection

Overload protection

4 steps gear limit switches(up, down, low speed up-approach, phase fault protection)

Hoist hydraulic brake

Electric wire rope hoist:

All the standard which is required for the crane is the Chinese standard.

Design and construction rules:

Capacity:1t-20t
Span:5m-27.5m
Lifting mechanism:electric hoist
Working environment:-20-40 degree centigrade.
