Double Girder Rail Electric Gantry Crane

Part1 Design&Features&Specifications of double girder rail electric gantry crane:

 

Double girder rail electric gantry crane is used when heavy loads,wide spans or high working frequency are required than single girder EOT crane. Double girder cranes consists of two torsion-free box girder . This makes double girder cranes especially suitable with load capacities up to 450t and with spans up to 50m. Heavy duty end carriage joints ensure positive contact of all four wheels with the track.

 

All movements of the crane are controlled in the cabin,either rigid shapes of steel(angles or tees)or flesible insulated cable shall be selected to be utilized as runway conductors and proposed in the order by the purchaser.

 

Max and min value of environment temperature,the short of power supply,the voltage and the other data shall accord to the buyer's demand.

 

Part2 Electrical elements of double girder rail electric gantry crane:

 

Double girder rail electric gantry crane we produced is designed to meet the requirement stated in your specification,as well as for the operation 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 rubust steel plate control cubicles.

 

All movenment 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 the cable gland.
