ABSTRACT:
A loader and unloader for a plate roll machine has an extensible boom extending generally horizontally over the plate rolls of the machine from a stationary support frame to which the boom is pivoted at one end for vertical movement over the rolls. The boom telescopes through the action of a hydraulic cylinder from a retracted position in which the free end of the boom overlies the plate rolls to an extended position in which such free end extends outwardly beyond the plate rolls. Additional fluid cylinders pivot the boom vertically. A plate support carriage is pivoted to the free end of the boom for fore-and-aft tilting movement. The carriage has one or more rollers extending lengthwise of the boom for engaging and supporting a rolled plate at its upper inside surface. The boom is retracted and positioned vertically for supporting the plate as it is rolled in the plate rolls. The boom is extended while supporting the plate to remove the rolled plate endwise from the plate rolls, and is lowered while extended to lower the rolled plate to a support surface and disengage and withdraw the carriage from the plate.
