Details of Gantry Crane
Unique Feature
1) high reliability, safety, free maintenance rate;
a) work duty: FEM2M, M5
b) Protection class: IP55
c) Insulation class: F
d) continuing rate: 60% ( for the high class motor)
e) Cooling rate: 30% than normal crane
f) Over temperature protection: 170ºC
2) compact design, small size, low dead weight, low headroom
3) Low noise
4) Investment-saved---the workshop's civil work cost, due to crane's light dead weight and low wheel pressure.
5) Power-saved. The total motor power is much lower than normal design.
