Abstract: A cargo handling assembly for use with a mobile vehicle including a base frame which is capable of being mounted on the floor of the vehicle. The base frame has a pair of parallel spaced rail members. A carriage assembly having a pair of spaced parallel extension arms can be slidably advanced and retracted along the rail members. An opposing wheel arrangement, mounted on each extension arm, creates an opening for receiving a length of each parallel spaced rail member, whereby the carriage assembly is horizontally translatable along the length of the base frame by movement of the opposing wheels along the spaced rail members.
