ABSTRACT:
A load transfer trailer which is utilized as an addition to the main frame of a transit concrete mixer and which provides an auxiliary axis assembly to the rear of the normal frame which carries a portion of the load of the mixer. The auxiliary axle assembly can be retracted and stored in a raised position when it is not needed. Control of the auxiliary axle assembly is achieved through the use of a spring for raising the frame for the axle and an air-hydraulic pressure system for lowering the axle. Mechanical latching members that latch the axle and support wheels securely in retracted position are also provided.
