CST30 Gearbox

Cat® Controlled Start Transmission (CST) drive systems optimize the use of power for maximum production capacities. Ever more powerful systems require ever more horsepower, heavier chains and faster conveyor speed with maximum availability. What was needed was a truly intelligent drive system for face conveyors, which led our engineers to develop the Controlled Start Transmission (CST) drive system meeting the following requirements: • Currently available power up to 1200 kW (1,950 hp) per transmission unit • Safe startup of the face conveyor • Full utilization of the installed power • Highly durable components • Compact dimensions • High level of efficiency
