ABSTRACT:
A generally U-shaped frame is formed with a pair of elongated beams, each having a pair of pivotally mounted load-engaging dogs, and with a pair of elongated sleeves, each extending upwardly from the free end of one of the beams. An elongated post is slidably and telescopically mounted in each of the sleeve. Each post is mounted on a wheel-supporting carriage. A hydraulic jack is mounted in each of the telescoping post and sleeve assemblies to raise and lower the frame relative to the base assemblies. Hydraulic motors and lines are provided so that the dogs can be pivoted and the frame raised and lowered by the operator of a fork lift which is attached to a hitch extending from the closed end of the frame.
