Tower Crane  Slewing Block

 

No. 1 omd slewing block, slewing controller (162A) for tower crane

The main technical feature as follows:

1. This product combined the controller and thyristor module, the connection of the users is simple and easy. This is to prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
2. Realize the best optimization of AC voltage control curve and DC voltage control curve.
3. With the function of inching during operation, realize the accuracy.
4. The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
5. Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
