    摘要: A method and apparatus for positioning and supporting the work platform of a mobile workover rig is disclosed. The work platform of the preferred embodiment of the present invention utilizes a unique support structure and automated positioning system for positioning the work platform at the desired height above the wellhead equipment. The preferred embodiment of the present invention utilizes a specialized automated “pinning” system that secures the work platform at the desired height. Additionally, the present invention utilizes one or more support cylinders to position and support the work platform in the horizontal position over the wellhead equipment. The automated positioning and pinning system of the present invention is a unique system that significantly reduces the time required to position the work platform of a mobile workover rig in the operating position, as well as significantly reduces the risk of injury to rig personnel assisting in the positioning operations.

    摘要: A sweeper unit well-suited for use for sweeping paved areas includes a debris-retaining hopper with an associated fan assembly that includes an air outlet duct for connection to one side of a pick-up head and an inlet duct for connection between the other side of the pickup head and the debris-retaining hopper. A fan drive arrangement includes at least a first and a second hydraulic displacement device to drive the fan and, when required, provide a flow of hydraulic fluid for auxiliary devices including the gutter broom motor(s).
