Product Description:

1 Application

  RCV slewing controller is a tower crane hoisting slewing controller device combined of three-phase AC variable voltage control and eddy current speed control.

 After connection with the vortex torque motor and reduction box,through the potentiometer voltage instruction on the operation panel,to control the thyristor trigger conduction abgle of three-phase AC current and eddy current, so that control the rotation speed of eddy current torque motor,realize the smooth start,operation and stop of the tower crane slewing system.
