The drum of Cable drum engines (CDE) is driven by multiple variable frequency motors (or hydraulic motors), reducers, gears and ring gears. During construction, drum cable laying machine forms an operation line together with the sliding pair wheels (D0HB), cable guiding device (Diverter), storage drive equipment etc.
