ABSTRACT:
A wheel suspension system for special event trailers is constructed in two opposite side laterally narrow and compact units attached to the lower perimeter frame of the trailer body. The trailer body is elevated to a transport position and lowered to a stable ground level position convenient for customers by the operation of horizontally movable cam lift plates powered by horizontal axis hydraulic cylinders in cooperation with vertical axis carriage plates having cam followers. Longitudinal leaf springs rockably mounted on the carriage plates have lost motion connections with tandem wheel axles carried by crank arms pivotally attached to the lower perimeter frame.
