Beschreibung
Zusammenfassung:	An aerial work platform apparatus includes a shiftable counterweight (36) which shifts in response to movement of the boom (32) in order to maintain optimum balance of the apparatus during movement of the boom and platform (22). The counterweight shifts towards and away from the front of the apparatus, and also in a vertical direction. The counterweight is supported by rollers (40) and moves along an inclined track (42). The counterweight is pushed by a link (46) mounted on the second (32') end of the boom, or in an alternative embodiment by a hydraulic cylinder (58), which is linked to the boom lift cylinder (54) in a master-slave arrangement.
