Auxiliary drive
The auxiliary drive motor is dimensioned so that it is possible to operate the conveyor system
under no-load conditions at low speeds in the same direction of rotation.
The auxiliary drive is 󹪞anged to the main gear unit through an intermediate 󹪞ange. The auxiliary
drive is a bevel geared motor that is coupled to the main gear unit via an overrunning clutch. The
overrunning clutch is accommodated in the intermediate 󹪞ange, and is supplied with oil from
the main gear unit. The auxiliary drive has its own oil.
