The motive power unit is available in three sizes depending on the length of the passage.
All motive power units have a hot-dip galvanized steel frame. The diameter of the drawing drum is 200 mm, with the exception of the 0.9 kW power unit, in which it is 250 mm.
The motive power unit is attached either to a concrete wall or to the floor on its RHS legs. The motive power unit can be equipped with a wire guide which guides the wire evenly onto the drawing drum and increases the usable life of the wire.
