Abstract
A quick coupling for connecting a side shift cylinder of a carriage attachment to the lift carriage of a lift truck includes a pair of laterally spaced mounting blocks extending between and welded to the upper and lower cross frame members of the lift carriage to provide a mounting space therebetween. A rear portion of a mounting plate extends into the mounting space, and a pull pin extends through aligned openings of the blocks and plate to removably connect the plate to the lift carriage. A forward portion of the plate projects forwardly beyond and overlaps the front faces of the carriage cross frame members and has an opening therethrough which receives a piston rod extension of the side shift cylinder of the attachment. A second pull pin extends through an opening in the leading end portion of the extension to removably connect the side shift cylinder to the mounting plate. Thus the side shift cylinder can be quickly disconnected from the mounting plate, and the mounting plate quickly disconnected from the lift truck carriage to enable the carriage to be used in a conventional manner by pulling the two pins.
