5.17.2 Auxiliary drive, designed as a load drive

Unlike the maintenance drive, type CF MOTOX worm­geared motors or type CSFW CAVEX cylindrical
worm­gear units are used here for the auxiliary drive. The motors of the auxiliary drives are dimensioned
in such a manner that a properly loaded conveyor system can be operated at low speed in the same
direction of rotation. The motors of the auxiliary drives are fitted with a spring­loaded brake so that
detrimental overspeeds are avoided in case of malfunction of the overrunning clutch.
For the exact designation of the geared motor as well as the mounting position please refer to the drawings
(see section 1, "Technical Data"). The auxiliary gear unit has its own oil circulation system which is
separated from that of the main gear unit. The auxiliary gear unit is already filled with oil when delivered.
