ABSTRACT:
A side loader main frame includes front and rear sections which are rigidly interconnected by a bridge to form a pocket for a laterally traversing mast. The bridge is a boxlike torque tube with openings in the laterally inner vertical wall through which transversely extending guide structures for the traversing mast extend. The traversing mast has a pair of supports with rollers which extend into the openings upon lateral retraction of the mast, thereby permitting the uprights of the mast to be closely adjacent to the bridge. The bridge includes a pair of laterally spaced and longitudinally extending vertical walls, horizontally disposed top and bottom walls and a pair of horizontal intermediate walls spaced above and below the openings, respectively. The frame is constructed to obtain great strength and yet keep the bridge relatively narrow in lateral width. The provision of openings in the bridge permits the uprights of the mast to be retracted to a position adjacent the bridge, thereby allowing the full decks of the front and rear sections of the frame to be used for load support.
