20FT/40FT Double Girder Gantry Container Crane

Introduction:

Container gantry crane applies to international standard container transporting, loading and unloading at the container yard and railway container depots, with stable performance, high efficiency and ease maintenance having proper safety instructions and overload protection devices to maximizely ensure the safety of operational personnel and equipment. Electrical system uses PLC frequency adjustment which can easily control every mechanism.

This kind of crane is divided into tire type and track type. The tire type has good mobility and small sensitivity on the surface roughness. This kind of crane using diesel generators for power supply can work under low temperature with its oil and hydraulic system has heating device. The crab of rail type can rotate and the over crab can pass the gantry legs making the scope of operations wide and flexible.

Crane girder:

The crane girder is of welded girder construction. This result in lower dead weight with a high degree of vertical and horizontal rigidity and small wheel loads being transmitted to the crane runway!

Electric equipment:

All electric equipment can works normally within the voltage fluctuation range -15% or +10%. We also design the protection devices, for instance, the emergency stop system, current overload protection system, voltage lower protection function, and etc. The main electrical components (frequency inverter, PLC) adopt the Siemens, Schneider, Chint or other international famous brand.
