Double Girder Rail Traveling Electric Gantry Cranes With Trolley
Product Description
Double Girder Rail Traveling Electric Gantry Cranes With Trolley are made up of bridge, trolley, crane traveling mechanism and electric system.All the procedures are finished in the operating room. Applies to the open warehouse or rail along for general handling and lifting work. Also can equipped with many lifting device for special work. Prohibited for lifting high temperature solution, flammable, explosive, corrosion, overloading, dust and other dangerous operations.

Matters needing attention
Double Girder Rail Traveling Electric Gantry Cranes With Trolley is composed of wheel group, hook group, drum group, motor, reducer and other accessories. In the use of the process is easy to occur in the fault is chewing rail.
Chewing the track will aggravate the track wear, increase the running resistance, reduce the service life of the wheel, serious damage to the beam structure, even cause derailment accident.
There are many reasons for the formation of gnaw rail, mainly the following:
1. There is a fault on the track surface. Oil or ice on the track surface was not cleaned in time.
2. The corrosion and deformation of metal structure, especially the gantry crane used outdoors, caused the diagonal deviation of the trolley frame due to the corrosion and deformation. The long-term use of the bridge frame is in a diamond shape, resulting in the wheel chewing the track.
3. Poor installation accuracy of big car wheels. The horizontal and vertical direction of the wheel is deviated and out of tolerance. The pressure per unit area of the wheel track is too large due to wear and tear, resulting in uneven wear of the wheel and the phenomenon of rail gnawing.
4. The motors at both ends of the drive have different rotational speeds, and the braking torque of the brake shafts at both ends is different, resulting in inconsistent speed of the wheels on both sides and out-of-sync operation, resulting in track biting.
Troubleshooting of gantry crane operating mechanism
Removing the effects of oil or ice on the track; Adjust the trolley track to meet the installation technical requirements; Check the transmission chain connection, bolt connection, gear coupling engagement and other conditions to eliminate excessive clearance, so that the two ends of the transmission is consistent; Adjust the accuracy of wheel installation. If L and h are measured horizontally and vertically respectively, the horizontal skew is less than L/1000, and the perpendicularity deviation is less than h/1000. Change the starting mode of the motor or replace it with a wound rotor motor, check to ensure the two electric synchronous.
