Abstract
A spreader for lifting containers comprises a generally rectangular frame having container engaging devices adjacent the corners thereof and being mountable on the tines of a fork truck or the like for movement rotatably about a generally vertical axis, and horizontally in directions both parallel and perpendicular to the longitudinal axes of the tines. The frame includes base and upper frames, and at least one of such frames includes an elongated slot extending generally parallel to one of the horizontal directions of movement. A pin extending outwardly from the other of such frames is received in the slot for restraining the upper frame against complete displacement from the base frame, as well as for guiding certain movements of the upper frame relative to the base frame. The upper frame is rotated and moved horizontally in a direction generally perpendicular to the longitudinal axes of the tines by selectively operable common power means which comprises a pair of hydraulic cylinders connected between the base and upper frames.
