MG double girder gantry crane

Remote control.

Cabin control.

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.

Type of enclosure IP 55

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 girders 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 girders and bracket legs:

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

Design and construction rules:

It is appicable to loading, unloading and transporting of goods at open warehouse, yard, rail freight station, port wharf, etc. It can also perform many kinds of paricular operations equipted with many special hooks. The gantry adopts double welding structure of box style. Trolley drive mechanism adopts separate driving. All the mechanism is controlled in the controlling room. Crane has two conductive styles as cables and slide wires. Users can choose either type. This structure has the advantages of strong load bearing capacity, wide span, overall stability and stiffness

The series products of doulbe-girder gantry crane are applied to do handling operations such as open warehouse,stock yard,railway goods station and port cargo handling areas etc.It also can do some special operations with many special load lifting devices.
