The bottom of the main beam of the crane adopts special heat insulation treatment,the working environment temperature is -10℃~60℃, and the relative humidity does not exceed 50% at a temperature of 40℃.
Mechanical Parts：
1.Bridge
The main beam is made of cold-formed U-channel steel and I-beam welded into a solid web beam or steel plate into a box beam. The end beam is a U-shaped channel steel group welded into a box structure, and the main and end beams are connected by bolts and shear flange connection structure or seat structure.
2.Lifting mechanism
The crane is equipped with two independent braking devices-the metallurgical electric hoist consisting of a brake and a safety brake (i.e. double brake) and an overload limiter form a lifting mechanism, which can lift heavy objects and move along the main the beam moves laterally.
Design Standard:
