ABSTRACT:
A lift structure for attachment to the frame of a truck fitted with a tandem axle assembly, one of the axles being a drive axle. The structure comprises a pair of spaced pivotally mounted bell-cranks adapted to reach under the trailing axle of the tandem axle assembly and hydraulic cylinders for rotating the bell-cranks to lift the rear axle when it is unnecessary to use the additional load-bearing axle.
