2.0 Introduction
Thank you for purchasing the Movotec
®
Q-Drive ATU Lift System.
The Movotec
®
Q-Drive 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
®
Q-Drive 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

USE OF TRAINED AND QUALIFIED PERSONNEL System installation, operation,
and repair should only be done by persons having sufficient knowledge of the lift system
and the contents of this manual. In addition, they must have an understanding of all
warnings and precautionary measures noted in these safety instructions. Furthermore,
these individuals must be trained, instructed, and qualified to switch electrical circuits
and equipment on and off in accordance with applicable technical safety regulations.
AVOID HAZARDOUS ENVIRONMENT. Do not operate the system outside. Do not
expose the system to damp or wet conditions. Avoid any chemical or corrosive
environments. Do not operate the system in the presence of flammable solvents,
propellants, and/or explosive materials (i.e. gas, vapor, dust, etc.) Avoid temperatures
outside of the system rated operating temperature range 41
°
to 113
°
F (5
°
to 45
°
C). Do
not subject lift system components to vibration and/or impact load conditions.
INSTALLATION SAFEGUARDS. Do not use the system for any purpose other than
its intended function. Before operating system, make sure that the workstation has a
minimum clearance of 2 in. (51mm) from any other object or structure to prevent
pinching or crushing hazards. Do not allow wall, cabinet, electrical lines, hydraulic or
pneumatic lines, or any other fixed structures to obstruct the movement of the
workstation during operation.
KEEP CHILDREN AWAY. It is not recommended that children operate this
electrically powered lift device. If this device is used by or near children, close
supervision is absolutely necessary.
OBSERVE DUTY CYCLE. The term duty cycle refers to the amount of time that a
motor or system is in motion versus the amount of time that it is resting. The Movotec
®
Q-Drive ATU Lift System is not designed to operate continuously without rest. It is
designed for intermittent use only and is rated for a 10% duty cycle. This means that if
the lift system is in motion for 1 minute, it must be at rest for at least 9 minutes before the
next operation. It is also important to note that the maximum system on-time is 1 minute.
To avoid damaging the system, the duty cycle must not be exceeded. Motor surfaces
can become warm after extended operation that exceeds the duty cycle. Provide adequate
ventilation to allow heat dissipation from within and around lift system components.
USE OF ACCESSORIES. Use caution when routing extension cords. Do not allow
cords to become pinched or stretched. Avoid positioning cords where they can become a
trip hazard. Use only spare parts and accessories authorized or supplied by Suspa
®
Incorporated. Do not replace or replenish lift system hydraulic fluid unless the fluid is
supplied by Suspa
®
Incorporated .
DO NOT INSERT OBJECTS. To reduce the risk of fire or electrical shock, do not
insert any objects into the system when powered.

MAINTENANCE SAFEGUARDS. Prior to performing any maintenance or service on
the device, remove the load from all lift cylinders and unplug the motor controller from
power source. The workstation or structure that the lift system is attached to should be
stabilized to prevent personal injury or property damage during maintenance or service
procedures.
RETRACT SYSTEM BEFORE MOVING. To reduce the risk of property damage and
personal injury, always retract the lift system fully before moving the equipment.
UNPLUG BEFORE CLEANING. Retract the lift system, unplug the motor controller
from power source, and allow the system to cool before cleaning components. Clean
system components with a mild soap and water-damped cloth. Do not use corrosive
cleaning agents or high pressure wash systems to clean lift system components. Make
sure system is clean and dry before plugging into power source and operating the system.

4.0 How it Works
Movotec
®
Q-Drive Lift Systems are comprised of three major component subsystems; the
motor drive, the pump, and the lift cylinders. This section will explain how each
subsystem works together to make the lift system extend and retract.
Movotec
®
Q-Drive Schematic
4.1 Extension Cycle
The motor drive consists of a motor controller, a 24 VDC gear motor, and a motor
switch. The motor controller converts AC line voltage to DC voltage to operate the 24
VDC gear motor. It also controls motor speed and is programmed to operate within
specific pump upper and lower limits. The motor switch is used to activate the 24 VDC
gear motor for lift system extension and retraction.
When the motor switch “UP” arrow button is depressed, the 24 VDC gear motor shaft
begins to rotate in a (CCW) counter-clockwise direction. Since the gear motor drive
shaft is mechanically coupled to the pump leadscrew shaft, the leadscrew shaft rotates in
the same (CCW) direction. As the gear motor continues to rotate in a (CCW) 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

P/N: 670-00029A
2/17/12
7
lift cylinders causing them to extend. The gear motor will automatically shut off once the
programmed pump upper limit is reached.
4.2 Retraction Cycle (Refer to Movotec
®
Q-Drive Schematic on page 7)
When the motor switch “DN” arrow button is depressed, the 24VDC gear motor shaft
begins to rotate in a (CW) clockwise direction. Since the gear motor shaft is
mechanically coupled to the pump leadscrew shaft, the leadscrew shaft rotates in the
same (CW) direction. As the gear motor continues to rotate in a (CW) 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. The gear motor
will automatically shut off once the programmed pump lower limit is reached.
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.
