Less Wear. Extended Service Life.

Cat CST drives have proven their productivity and reliability in challenging mining conditions all over the world. They are able to start the conveyor even when it's heavily loaded, and carry those heavy loads quickly and efficiently. They also protect the conveyor from damage caused by rock jams and allow for better control of conveyor speed.

Smooth operation leads to reduced wear on the drives, chains, sprockets, flight bars, line pans and drive ends. That means a longer life and reduced maintenance.

First-Ever CST Drive Still Running Strong

Back in 1994, Caterpillar produced its very first Cat Controlled Start Transmission (CST) gearbox – “Serial No. 1.” During its 20-year service life, it has operated at two top-producing mines in the United States, mining a total of 60 million tons of coal.

Today Cat CST drives continue to set the industry standard for quality, durability and cutting-edge conveyor drive technology.
