Drive tractors;
This simple effective technology has been used effectively
in the industry for many years and has been perfected by our engineers
over time. Drive tractor units consist mainly of pneumatics
as they are used in conjunction with the platform's built in guide wheel to
provide a bicycle type motion control.

The center mounted guide wheel is pushed against the floor
using an air actuator to gain traction without carrying the load.
The drive tractor interlocks with the platform to provide
steering and motion.
A control panel mounted on the main stem provides air
supply control over the air casters and also to the guide wheel.
A handlebar has twist control for forward and backward
motion and has a handy "dead man handle" for emergency cutoff.

Drive Tractor Interlock: This hookup gives
full directional control of the platform, "Dead Man" control of the main air
supply to the Air casters is from the main control console. Clenching the leaver
handle on the console of the drive tractor raises the platform using further
controls adjusting the pressure to the tractor for traction control, the air is
on; release and the air shuts off.
