4.0 How it Works
Movotec
®
Crank Driven “Bolt-On” 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

03/01/16
670- 00017B
5
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

7.0 Installation Instructions
FOLLOW ALL SAFETY INSTRUCTIONS CONTAINED
IN SECTION 3.0 OF THIS MANUAL BEFORE
INSTALLING THIS PRODUCT. FAILURE TO
FOLLOW THE INSTRUCTIONS IN THIS MANUAL
COULD RESULT IN PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
7.1 System Component Placement
Movotec
®
Crank Driven “Bolt-On” Lift System components are physically linked
together with hydraulic tubing. Therefore, it is very important to make sure that the
system components are located on the workstation so that each component can be
installed safely without damaging the hydraulic tubing. It is also important to make sure
that the crank has enough clearance to rotate freely beyond the work surface.
7.1.1 Crank Driven Pump Placement - The crank driven pump can be installed
in any orientation, however it is recommended to mount the unit horizontally.
The pump should be installed so that there is enough hydraulic tubing to reach
each lift cylinder and enough clearance for the minimum hydraulic tubing bend
radius of 2 in. (51mm) to be maintained. The crank should be located near the
edge of the work-surface. Suspa
®
Incorporated offers other cranks and crank
hardware options which can be purchased on our website at
https://shop.suspa.com/storefront.aspx.
7.1.2 Lift Cylinder Placement – The lift cylinders should be located on the
workstation so that the load on the system is balanced. Lift cylinders must also be
oriented vertically and parallel to one another to prevent cylinder binding during
extension and retraction cycles. Suspa
®
Incorporated offers an assortment of
brackets to reduce the number of holes to be drilled for lift cylinder mounting and
to facilitate system installation. These cylinder mounting brackets can be
purchased on our website at https://shop.suspa.com/storefront.aspx.
7.1.3 Hydraulic Tubing Placement – Hydraulic tubing must be kept away from
sharp edges and moving parts. Contact with moisture and heat must also be
avoided. Hydraulic tubing should fixed to the workstation or structure using
cable ties and mounting clips. Cable ties and mounting clips can be purchased on
our website at https://shop.suspa.com/storefront.aspx.

To avoid lift cylinder damage, the screw depth must not
exceed 7mm (0.27 in.) into the lift cylinder housing as
shown below.
•Install each cylinder to the workstation frame using (4) - M5 screws of the
appropriate length. Suspa
®
Incorporated recommends a lift cylinder mounting
screw thread engagement of 0.196-0.275in. (5-7mm).
•Ensure that there is enough flexible hydraulic tubing to reach each workstation leg
without putting any tension on the tubing and while maintaining the minimum
flexible tubing bend radius of 2in. (51mm). Each standard system is shipped with
hydraulic tubing cut-to-length and assembled to the unit, (2) lengths at 8.2 ft.
(2.5m), and (2) lengths at 10.2 ft. (3.1m). Custom lengths of tubing can also be
ordered.
•Check the lift cylinder mounting screws to ensure that they are tightly secured to
the workstation. Take special care not to over tighten lift cylinder mounting
screws. Suspa
®
Incorporated recommends a lift cylinder mounting screw
tightening torque of 4.0-4.5 N-m (35-40 lb-in).
