Installation for 2set 130t/32t-span28.5m european double girder overhead crane for power plant

The crane's running mechanism and hoisting mechanism should adopt the variable frequency speed control system. We provide the actual operating experience of the variable frequency speed control system. The frequency converter uses ABB, ABM, Schneider, Siemens and other brands of the same grade.


The crane parameters as followings: 

Main hook: 130t, normal lifting speed 1.6m/min

Auxiliary hook: normal is 8.0m/min

Trolley traveling: normal 20m / min

Crane traveling: normal 30m/min

When the main and auxiliary hooks are continuously adjusted, the ratio of the continuous minimum frequency adjustment speed to the maximum frequency adjustment speed is about 1:15.

When the large and small cars are continuously adjusted, the ratio of the continuous minimum frequency adjustment speed to the maximum frequency adjustment speed is about 1:25.
