Van Gorp’s Turbine Discs are “State-of-the-Art” conveyor pulleys used on high tonnage steel cable belt systems where belt tensions can often exceed 200,000 pounds. These systems require a special pulley designed to minimize the inherent stresses in a pulley, which result from the rolling and welding processes during fabrication. The integral hub-end disc turbine replaces the critical hub to end disc welds of a regular drum pulley with a large transitional radius designed to minimize stress. The only weld on the end disc is where it is welded to the rim, which is at the lowest stress point of the end disc.
