The honeycomb beam gantry crane is original designed by our company. The main girder structure is an isosceles triangle welded by steel plate and channel steel. The holes honeycomb girder gantry crane making on the surface of the main girder can largely reduce the wind force. For the same type of the gantry crane, the total weight of the honeycomb beam gantry crane is between box-girder and truss-girder. The high rigidity and short installation period make this product applicable to workshop, depot and highway projects to lift freight. 

 

In order to make sure the safety of gantry crane in kind of construction, safety devices are following;

A. trolley transverse limit switches on both sides;

B. girder lifting height limit switches:

C. windlass low-speed shaft brake:

D. crane traveling limit switch;

E. emergency stop switch, there are total power emergency stop switch on the crab operating plate.

F.  lifting capacity limiter.

G. control interlock

 H. control room’s door limiting displacement
