Crusher Drive

This crusher drive was the brain child of Philip Maree of OST-Africa that developed this size belt drive with self-tensioning functionality. The belt life has improved by three to five times relative to the rigid mounted motors. The design and engineering was performed by our team of engineers, inclusive of the FEA.
