Air Powered Drive Units

The Air Drive moves the equipment at varying speeds up to a maximum of 40 feet / minute requiring only compressed air as a power source. Thumb controls with motorcycle style grips give the operator precise variable speed control in both the forward and reverse directions. The drive is equipped with a quick attach feature to allow simple connection and removal from the load. This allows a single drive to be shared by many pieces of equipment with the purchase of additional quick attach plates. The quick attach feature also allows the drive to be stored out of the way when not in use. The operator’s control console has an on/off switch, emergency stop, and gauges to monitor air inlet pressure and drive wheel traction pressure. The drive has two (2) air stroke actuators that force an elastomeric drive wheel down against the operating surface. The drive wheel traction pressure control located on the operators control console controls the amount of drive wheel “down” force, hence the amount of traction. The pressure in the air stroke actuator is monitored by the pressure gauge located on control console. The pressure also functions as an automatic air suspension system for a smooth ride. Drive torque is transmitted to the drive wheel by a piston style air motor through sprockets and chain and develops over 1200lbs of draw bar more than enough to move and control the load. This motor has been designed for high torque at low speeds with finite control for load positioning. The piston style air motor provides the additional advantage of providing dynamic braking which helps slow the load travel speed when the throttle is released. The drive housing is constructed heavy wall plate for superior durability in a harsh industrial environment. The drive also includes an integral filter lubricator to simplify the interface process and maintenance program.
