ABSTRACT:
A retractable wheel apparatus adapted to be attached to a frame and having a first and second arm pivotally attached along the horizontal axis. Each end of each suspension arm has a wheel assembly attached thereto and each suspension arm has a combination shock absorbing and retracting mechanism attached thereto. The first and second suspension arms are independently pivotally attached so that they can react independently to bumps in the road. Furthermore the suspension arms can move to independently pivot as a unit about the first horizontal axis to travel over irregular terrain so that the two-wheel assemblies can pivot about the first horizontal axis to minimize the amount of reciprocation of the wheel assemblies with respect to each other, which would cause excessive wear and a rougher ride. The frame is U-shaped with an open rear portion thereof so that the frame can be lowered by the retracting apparatus and backed under a container, at which time the retracting apparatus can be raised to pick up such container and transport it to its final destination, at which time a reverse procedure can be utilized to unload such container.
