Abstract
A modified theatrical counterweight apparatus (10) in a double or single purchase counterweight system (12) consists of an improved counterweight arbor carriage (50), for holding a plurality of improved counterweights (56). The improved counterweights (56) are stored on two elongate arbor bars (48), which when released will slide down into the improved counterweight arbor carriage (50). The improved counterweight arbor carriage (50) when obtaining the proper amount of the improved counterweights (56), will now slide down the elongate arbor bars (48) to raise a piece of scenery (34) with a batten (36) up from a stage (14), via lift lines (38) and an operating line (42).
