    • The elevator work platform assembly comprises a base movable over ground, an intermediate platform, a first stairway pivotally linked to the base and the intermediate platform and leading from one to the other, a work platform, a second stairway pivotally linked to the intermediate platform and the work platform and leading from one to the other, a linkage pivotally linked to the base and the first and second stairways, and an actuator capable of actuating the linkage and first and second stairways to move the work platform between a collapsed position in which it is adjacent to the base and a deployed position in which it is located away from the base. The stairways have self-levelling steps to allow access to the work platform in all positions thereof between the collapsed and deployed positions.

    • The hydraulic boom system can include a boom receiving a work platform; a fixed component fixedly mountable to the vehicle; a rotary component, rotatably mounted on the fixed component about a vertical axis; a pivotal component, pivotally mounted to the rotary component about a horizontal axis, and receiving the boom; a hydraulic power unit having an electric motor driven hydraulic pump; and an electrical cable connected to the electric motor, and connectable to an electrical power supply located at a fixed position relative to the vehicle. The hydraulic power unit can be made integral to the rotary component. A raising hydraulic cylinder can extend downwardly inside a spacing in the fixed component. The electrical cable can have a coiled portion housed in the fixed component and coiled around the vertical axis.
    • 液压动臂系统可以包括接收工作平台的吊杆; 可固定地安装在车辆上的固定部件; 旋转部件,围绕垂直轴线可旋转地安装在固定部件上; 枢转部件,围绕水平轴线枢转地安装到所述旋转部件,并且接收所述起重臂; 具有电动机驱动液压泵的液压动力单元; 以及连接到电动机的电缆,并且可连接到位于相对于车辆的固定位置的电源。 液压动力单元可以与旋转部件成一体。 升高液压缸可以在固定部件的间隔内向下延伸。 电缆可以具有容纳在固定部件中并绕垂直轴线盘绕的盘绕部分。
