Inverter Control Overhead Crane

Inverter Control Overhead Crane

The frequency conversion speed double-beam crane is mainly equipped with inverter or PLC to achieve stable operation of each operating mechanism. The main frequency conversion speed control operating mechanism includes: main lifting mechanism, auxiliary lifting mechanism, cart running mechanism and trolley running mechanism. For small tonnage cranes (10t and below), there is generally no sub-lifting mechanism. The main and auxiliary hoisting mechanisms and the trolley running mechanism are each driven by a YZR series wound-type motor, and the trolley running mechanism is generally driven by two YZR series wound-type motors.

Inverter control overhead crane performance characteristics:

1. The work reliability is significantly improved, eliminating the weak link of the motor. The control system can be greatly simplified and the reliability is greatly improved.

2, the energy-saving effect is very considerable Winding rotor asynchronous motor in low-speed operation, the external resistance of the rotor circuit will consume a lot of electrical energy. 

3. The quality of the speed control is obviously improved. 

4, Can simplify the transmission chain Because of the stepless speed regulation.

Inverter control overhead crane application range:

The working level of variable frequency speed control double beam crane mainly includes A5, A6, A7, A8, etc. It can also be transformed into frequency conversion speed regulation explosion-proof crane, frequency conversion speed metallurgical crane, frequency conversion speed regulation electromagnetic or grab crane. It is suitable for lifting work in mechanical processing, assembly workshop, metal structure workshop, metallurgy and foundry workshop and various warehouses. The configuration grab is suitable for the transportation of granular materials in the industrial or industrial sectors such as metallurgy, cement and chemical industry.
