ABSTRACT:
A lift truck for carrying stacking chairs, the truck having a main frame carried on front and rear wheels and an elevating platform on the main frame and movable from a lowered inactive position to a stack lifting position. The forward end of the truck, which includes the main frame, front wheels and elevating platform, is of a width to allow the forward end to be pushed between the transverse spaced legs of the lowermost chair in the stack when the elevating platform is in the inactive position. The truck has rear wheel mounting structures which include arm sections which project forwardly of the rear of the lift truck and are disposed laterally outwardly from the sides of the main frame so as to position the rear wheels laterally outward from the main frame and forward of the rear of the main frame. The space between the arm section of the rear wheel mounting structure is open at the front thereof so as to receive the legs of a rear stack of chairs as the forward portion is pushed under the stack. An operator's handle is positioned in the rear of the main frame and a platform raising lever is located on the handle. The lift truck is readily maneuverable and is stable when carrying stacks of chairs which have relatively high centers of gravity.
