4. Main girder and end carriages are connected by 10.9 degree high-strength bolts, stable and durable;

5. Driven by electric reducer or traditional drive system;

6. Running smoothly, brake efficiently, long service life;

Electric:

1. Supplying power through steeples downshop conductor (bus bar);

2. The crane and hoist are mutually independent and able to work at the same time;

3. Etch-proof control handle with protection degree of IP54;

4. Electric cable is suspended in cable trolley which slides flexibly and smoothly on a C-type steel;
