Abstract
One embodiment provides a drive system that includes a drive device with at least one drum for spooling at least one wire rope. A mounting device is connected to the drive device and a single-axis tracker. At least one partial pulley is connected to a torque tube. The at least one partial pulley is configured to accept the at least one wire rope and to transfer leveraged drive forces to the torque tube.
