2.0 Introduction
Thank you for purchasing the Movotec
®
Crank Driven ATU Lift System.
The Movotec
®
Crank Driven ATU Lift System is a single-acting fluid displacement lift
system that is manually driven by a hand crank. This particular lift system was designed
to be used in conjunction with the Movotec
®
ATU or Aluminum Telescoping Upright.
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.
Suspa also offers a Movotec
®
ATU Workstation Kit. The workstation kit contains all of
brackets and hardware necessary to construct a complete height adjustable workstation
base and includes everything but the work-surface.
For over twenty years, Movotec
®
systems have been used on industrial workbenches,
small machine bases, physical therapy equipment, massage tables, office furniture,
biological and chemical vented hoods, autopsy and necropsy tables, sewing machine
bases, home healthcare beds, packaging equipment, custom yachts, and many other
applications.
Movotec
®
lift systems are subjected to life cycle testing on a regular basis. The tests are
performed in a temperature and humidity controlled environment under full system load
conditions. Movotec
®
lift systems perform consistently well in this controlled test
environment. However, due to the wide variety of possible lift system applications and
operating conditions, Suspa
®
does not warrant that any particular lift system is suitable
for any specific application. It is the responsibility of the person who specified the
system to determine its “fitness for use” in the application, through testing and analysis,
to ensure safe and reliable performance. A complete statement including terms and
limitations of the Movotec
®
Crank Driven ATU Lift System warranty can be found in
Section 11.0 of this manual.
Movotec
®
lift systems are assembled and subjected to a full function quality test before
they leave our manufacturing facility. Suspa guarantees products are free from material
and manufacturing defects, but cannot support the warranty for our products if they are
altered, misused, misapplied, or abused in any way. It is the responsibility of system
installers, users, and service technicians to read and carry out the instructions in this
manual correctly to prevent these potentially unsafe and unwarranted occurrences from
happening.
Thank you again for purchasing the Movotec

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.
Movotec
®
Crank Driven Schematic
4.1 Extension Cycle:
The crank is mechanically coupled to the pump leadscrew shaft. When the crank is
rotated in a clockwise (CW) direction, the leadscrew shaft rotates in the same (CW)
direction. As the crank continues to rotate in a (CW) direction, the threaded pusherblock
moves up the leadscrew in the direction of arrow “A”. This action drives fluid from the
pressure elements, through the hydraulic tubing, and into the lift cylinders causing them
to extend. As the cylinder load increases, the force required to rotate the crank increases.
Generally speaking, the crank force required to extend the system will always be greater
than the crank force required to retract the system. It is also important to note that when

01/11/2013
670-00028A
6
the pump has reached its upper limit, the user will feel increased resistance at the crank
handle.
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. As the crank continues to rotate in a (CCW) direction, the threaded
pusherblock moves down the leadscrew in the direction of arrow “B”. As long as there is
sufficient load on the lift cylinder piston rods, the fluid in the lift cylinders flows back
through the hydraulic tubing and into the pressure elements. It is important to note that
the user will feel increased resistance at the crank handle when the pump has reached its
lower limit.
5.0 Unpacking Instructions
The system comes packaged in a cardboard carton. To unpack the system:
•Check the carton label to confirm that you have received the correct system; open
the carton and remove packaging material.
•Carefully remove the system from the carton, and verify all components are
present (reference chart below), and that the correct lift system was received.
Do not handle the lift cylinders and motorized pump by the hydraulic tubing. Incorrect
handling of hydraulic tubing could weaken the tubing material and system tubing
connections.
DAMAGE TO TUBING OR TUBING CONNECTIONS
COULD CAUSE FLUID LOSS AND UNCONTROLLED
DESCENT OF THE WORK-SURFACE.
