Structure of Honeycomb Girder Gantry Crane (1)

 
ZZHZ Honeycomb girder gantry crane is made up of crane moving system, gantry mounting, operating cab, main longitudinal girder, walking platform, lifting trolley and electric hoist and etc.

1. Crane Moving System of Honeycomb Girder Gantry Crane:
 
Crane moving system of honeycomb girder gantry crane is composed of two driving wheel boxes and two driven wheel boxes. There is a drive walking wheel box and a driven wheel box included in driving wheel box. Outside of the wheel box,there is cycloidal pin gear speed reducer with braking motor. While the wheel box is working, braking motor drives the reducer, a couple of exposed gear pass the power to driving wheel, therefore wheel box drive the crane moving system to travel forward along the track. If the honeycomb girder gantry crane stops, braking flange of the de-boost motor will reset to make sure the braking motion immediately. Motor adopts frequency converting control, which is beneficial to working life of the honeycomb girder gantry crane.
 
Driven wheel box is similar to driving wheel box, but there is something different, driven wheel box is not designed with some transmission mechanism, such as motor, reducer and a couple of exposed gears.
 

2. Gantry Mounting of Honeycomb Girder Gantry Crane:
 
Gantry mounting of honeycomb girder gantry crane includes outriggers and transverse girder. All the junctions are connected with pin seals, it is convenient to be installed and fixed.
 
There is a row of ladder welded on the inner outrigger, so that operators can go into the operation or go up the walking platform via the ladder.
 

3. Operation Cab of Honeycomb Girder Gantry Crane:
 
Operation cab of the honeycomb girder gantry crane includes operation cab itself and electric control cab. Outside of the outriggers of honeycomb girder gantry crane is welded by steel plate. Supported by shaped steel, operation cab of the honeycomb girder gantry crane is installed in the middle of inclined outrigger and straight outrigger. In the front and both sides of operation cab there is installed glass windows, so that operators can watch all the working situation.
 
Electric box is an independent cabinet, it is installed outside of the operation cab, connected by controlling cable and hand grip. Hand grip is set in the operation cab. When the honeycomb girder gantry crane is working, operators can control all the motions of the crane by the buttons of hand grip.
