Abstract: A vehicle includes a vehicle chassis, a load support body connected to the chassis and movable between a lowered position and a raised position, and a hoist operable to forcibly move the load support body from the lowered position to the raised position. The hoist includes a cylinder and a pressurized drive fluid supply system. The cylinder includes a housing assembly and a shaft assembly. The housing assembly defines first and second cylinder chambers separated by a center cap. The shaft assembly is slidably mounted in the housing assembly and includes a shaft and first and second pistons affixed to the shaft at axially spaced apart locations along the shaft. The first piston is disposed in the first cylinder chamber and the second piston is disposed in the second cylinder chamber.
Abstract: A hoist is provided, which includes a hoist frame, a torque arm coupled to the hoist frame, and a lift arm coupled to the torque arm. The hoist also has a cylinder operatively coupled with the torque arm. The cylinder includes a cylinder shaft with multiple pistons disposed on the cylinder shaft. The multiple pistons define multiple piston chambers within the cylinder where, during operation of the hoist, the multiple pistons simultaneously operate to effect operation of the hoist.
