The pit for the drive and the cable routing for the electric drive are provided on site by the customer.

The system is equipped with a geared brake motor controlled by a frequency converter. The motor moves a friction wheel which, spring-loaded (gas pressure springs), which is pressed onto the circumferential diameter of the turntable and therefore initiates the rotational movement.

The electric control is activated manually using operator safety devices (dead man's switches) in conjunction with limit switches on reaching the respective end position. The control or switchbox is installed in a fixed position, approx. 3 m next to the turntable (near the gage). Movement of the turntable is signalled by means of a flashing light and horn.
