Abstract: A pump enable system includes a variable-displacement piston pump (10, 110) having a displacement control device (22, 122). The displacement control device (22, 122) controls displacement of pistons in the pump (10, 110) based on a position thereof, and a position control system (24, 26, 28, 124, 126) in the pump (10, 110) controls a position of the displacement control device (22, 122) based on a load on the pump (10, 110). An over-ride system (52, 152) selectively over-rides the position control system (24, 26, 28, 124, 126) such that the displacement control device (22, 122) assumes a position which reduces displacement of the pistons in the pump (10, 110).

Abstract: The aerial work platform includes a support frame (1, 4), wheels rotatably attached to the support frame (1, 4), and an electric motor (72) rotatably driving at least one of the wheels. A boom (5) having a first end is pivotably mounted to the support frame (1, 4), and a fluid motor (21) raises and lowers the boom (5) with respect to the support frame (1, 4). A work platform (8) is supported by a second end of the boom (5). A battery pack (54) supplies power to the electric motor (72). A first support structure (60), for supporting an auxiliary power plant that supplements power supplied by said battery pack (54), removably attaches to the support frame (1, 4).

Abstract: 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.
