Abstract
A drive unit has at least one motor, a motor stand, a bearing block, a drive pulley and a counter-roller attachment. The drive pulley is mounted at the motor stand and at the bearing block by a shaft. A respective brake is arranged at the bearing block at each side. Webs connect the motor stand with the bearing block. The motor stand, the bearing block and the webs form a stable structure without an engine frame carrying the motor stand and the bearing block being necessary. A counter-roller attachment consisting of side plates and a counter-roller is arranged directly at the motor stand and the bearing block.
