Airfloat Drive Tractors can safely enable one person to easily move the heaviest of loads. Combined with drive units, even frequently moved and unrestrained loads exceeding 10,000 lbs can be positioned to your specifications.

The air motor powered drive tractors provide all the steering and moving forces needed while operated off the same air supply line as the air bearing platforms. The twist grip controls forward and reverse speed and provides “deadman” on/off control of air bearings. Drive tractor includes a mounting bracket for quick attachment and transport of wheels for manual movement when one tractor is used for multiple platform applications. Requires the use of a guide wheel for proper steering. These can also be used for powering wheeled carts. *note* Deadman air control requires purchase of optional pendant control to provide platform mounted valve.

• safe, one-man operation, even with heavy loads
• simple controls & full 180° steering
• quick attachment enables tractors to be connected and disconnected in seconds

Consult the factory for additional drive systems including:

• Internal steerable drives with pneumatic or electronic control for 360 degree movement capability.
• Internal non-steerable drives for X-Y Rotate movement capability.
• Electronic motor powered drives.
• Turtle Drives

When to Use a Drive

Under ideal and controlled conditions, loads supported by air film equipment can be moved with just one pound of force per 1,000 lbs of a load. For most applications, conditions will be less than ideal. Surfaces that have defects (small cracks, rough areas, dirt or debris) will increase the amount of force required for movement. Minor undulations or slopes will add an even larger amount to the force required for heavy load movement. Generally, when loads exceed 10,000 lbs and movement is frequent and unrestrained (not guided), drive units are recommended.
