ABSTRACT:
Disclosed is a device for stabilizing an air spring dumping trailer during dumping operations. Suspension hangers are affixed to the main support frame in front of the rear axle. Arm members are pivotally connected to the hangers and extend rearward past the rear axle. An axle seat is mounted to each of the arm members and air springs are provided between the axle seats in the main support frame. The section of the arm member which cantilevers past the rear axle is provided with a chock. A second chock is mounted to the main support frame. During trailer dumping operation, the air springs are deflated allowing the first and second chocks to interact with one another thereby creating a load transfer means between the main support frame and the arm member thereby bypassing the air springs.
