ABSTRACT:
A trailer with a frame having a center load receiving channel for a motorcycle or for a similar load. A pair of oppositely extending wheel supporting axles are pivotally mounted near the center channel.
Bladder-type air cylinders extend between the frame and axles near the outer end of the axles. An air suspension system automatically controls the inflation of the air cylinder during transit and allows the user to selectively deflate the air springs to lower the trailer to a position close to the ground so a load such as a motorcycle can be rolled into the trailer. The user can then operate the system to inflate the air cylinder. Level control valves maintain the air cylinders at the proper position. A fail safe system maintains the trailer in an elevated position in the event of air system failure.
