    ® The Movotec ATU is a telescoping table leg which provides guide support for Movotec lift cylinders throughout their extension and retraction cycle. The ATU also offers a solution for customers who want to make their own height adjustable table, but do not have the means to manufacture their own telescoping leg.

  • Page 4: Safety Instructions

    VERIFY SYSTEM SELECTION. Before installing or operating the system, please ® review the application to confirm that the correct Movotec Lift System has been selected. Pay particular attention to the load capacity and adjustment range ratings listed on the blue product label.

  • Page 6: How It Works

    4.0 How it Works ® Movotec Crank Driven “ATU” Lift Systems are comprised of three major component subsystems; the crank, the pump, and the lift cylinders. This section will explain how each subsystem works together to make the lift system extend and retract.

  • Page 7: Retraction Cycle

    ® 4.2 Retraction Cycle: (Refer to Movotec Crank Driven Schematic on page 6) The crank is mechanically coupled to the pump leadscrew shaft. When the crank is rotated in a counter-clockwise (CCW) direction, the leadscrew shaft rotates in the same (CCW) direction.
