Details of the DT Hub
The DT Hub system uses mechanical springs to hold the shift clutch in direct drive and air pressure to shift the clutch and then hold the system in planetary drive. The planetary gear set stays (disengaged) in direct drive for high- speed highway operation. The direct drive is determined by the crown and pinion gear ratio in the truck. Shifting into planetary drive for low speed off-highway or heavy haul use produces a 3 to 1 gear reduction in the wheel end of the hub.
The DT Hub system incorporates standard North American brake components when fitted on to rear ends from Arvin Meritor Corp and Eaton/Dana Corp, and Mack. The DT Hub fits onto 23,000 and 26,000 pound rear end in a single axle, tandem axle or tridem axle configuration. It can be installed on to existing trucks with no alteration and can be removed if the truck is sold. The DT Hub system is ideal for oilfield rig moving trucks, heavy equipment haulers, pipeline stringing and equipment moving, coal haulers, open pit ore haulers, house and building movers, log haulers, soil cement spread trucks and tank trucks. The DT Planetary Hub system has been tested, proven and trusted in all types of road and field conditions.
