2.2 Main structure and principle
of the equipment
zLifting mechanism: Each of the two columns has
one hydraulic cylinder respectively. When the
power unit works, the hydraulic oil gets into the
lower chamber of the cylinder, forcing the piston
rod moves upward. At this time, the carriage
moves upward through the chain.
zSupporting mechanism: When the vehicle enters
into the working area, adjust the position of two-
stage telescopic swing arms to make the lifting
pad near the correct lifting point of the vehicle,
and then adjust the screw height below the pad
to adapt to different heights ofvehicle chassis.
zBalancing mechanism: To keep the balance
during the lifting and lowering process, the lift
uses two steel cables to interconnect two
carriages, forcing the carriages to rise and
descend synchronously. If the carriages and
swing arms are not on the same level, adjust the
screw at the end of the steel cable, making the
swing arms at the same level (equal position
from the floor). At this time, the steel cables
must be adjusted tightly with equal tension,
otherwise the equalization can’t be ensured.
zManual safety locking system: the safety locking
plates are installed on the two carriages and the
toothed bar plate is welded on the internal wall
of the column. During the lifting of the carriage,
Passing width 2486

LAUNCH Installation Instruction for Economical Symmetric Floor-plate 2-post Lift
4
the safety locking plate goes up against on the
toothed bar plate by the tension of spring. When
the carriage stops, the safety locking plate
opens and then is engaged in the toothed bar
slot to ensure the carriage will not go down;
when the lowering operation is required, just
raise the carriage upward a little to loosen the
safety locking plate from the toothed bar slot,
and then manually pull the steel wire rope so as
to jack up the safety locking plate by sliding
plate, so the safety locking is released so that
the carriage can be lowered down. Because the
manual safety locking systems are installed on
the two carriages, double safety protection can
be provided; therefore, to disengage the safety
locking, the steel rope on the two carriages shall
be respectively pulled.
zTo prevent the vehicle slip, the swing arm is
installed with positioning mechanism, making
the swing arm capable of automatic locking
during operation.
zSafety scope: The safety lock mechanism is
effective from the height of lifting pad 450mm to
1900mm.
3. Tools for installation
and adjustment
To ensure proper installationand adjustment, please
prepare the following tools:
Tool Model
Leveling instrument Carpentry type
Chalk line Min 4.5m
Hammer 1.5kg
Medium crescent wrench 40mm
Open-end wrench set 11mm-23mm
Ratchet socket set
Flat screwdriver 150mm
Rotary hammer drill 20mm
Concrete drill-bit ￠19mm
4. Unpacking
zOpen the packing box; remove the packing materials
and inspect the lift for any sign of shipment damage.
Check by packing list to see if the main parts and
accessories are complete.
zKeep the packing materials away from the children to
avoid danger; if the packing materials cause the
pollution, they shall be treatedproperly.
5. Installation
5.1 Important notice
zThe wrong installation will cause the lift damage or
personal injury. The manufacturer will not undertake
any responsibilities for any damage caused due to
incorrect installation and usage of this equipment,
whether directly or indirectly.
zThe correct installation location shall be “horizontal”
floor to ensure the horizontal lifting. The slightly slope
floor can be corrected by proper shimming. Any big
slope will affect the height of the lifting pad when at the
bottom or the horizontal lifting. If the floor is of
questionable slope, consider a visual inspection, or
pour a new horizontal concrete slab if possible. In
short, under the optimum horizontal lifting status, the
level of the lifting relies on the level ofthe floor where it
is installed. Don’t expect to compensate for the serious
slope.
zDon’t install the lift on any asphalt surface or any
surface other than concrete. The lift must be installed
on concrete floor conforming to the minimum
requirement showed in this manual. Don’t install the lift
on the concrete with seams or crack and defect.
Please check together with the architect.
zWithout the written approval of the architect, don’t
install this lift on a second floor with basement.
zOverhead obstruction: The lift installation area can’t
have any overhead obstruction, such as heater,
building support, electrical pipe, etc.
zConcrete drilling test: The installation personnel can
test the concrete thickness at each site by drilling test.
If several lifts are installed at one place, it is preferred
to make drilling test in each site.
zPower supply: Get ready the power supply before the
installation. All the electric wiring and connecting
should be performed by a certified electrician.
5.2 Installation procedure
5.2.1 Selecting installation site
Select installation site basedon the following conditions:
zIf the thickness of the whole ground concrete is greater
than 250mm, the lift can be installed directly.

LAUNCH Installation Instruction for Economical Symmetric Floor-plate 2-post Lift
5
zIf the thickness of the whole ground concrete is less
than 250mm, the concrete slab must be made.The
minimum thickness of the concrete slab is 250mm,
with 20 days of minimum curing time.
zThe concrete slab shall have steel bar reinforced and
must be leveled.
zCheck the possible obstruction, e.g. low ceiling, top
pipeline, working area, passage, exit, etc.
zThe front and back of the lift should be reserved with
sufficient space to accommodate all the vehicles.

5.2.2 Base plate layout
As shown in Fig. 4:
zWith total width (A) as the basis, draw two parallel
lines (#1 and #2) on the concrete slab, with the error
within 3mm.
zDetermine the powerside column location on any chalk
line, and mark the total width (B) of the base plate.
Mark the points 3 and 4.
zStarting from point 3, draw one diagonal line (C) to the
point 5 forming a triangle. In this way, the #1 and #2
lines can determine the location of the two columns.
Note:
zAll the dimensions are based on the external
border of the base plate.
Ensure the overall error is controlled within 6mm. In
this way, the difficulties in the final assembly, or early
wear or non-alignment of the chain can be eliminated.
The marking and layout is very important. If it is
inaccurate, there will be problems during the final
assembly and operation.
Entrance 4m recommended

5.2.3 Install the powerside column
First raise the powerside column upper right to the location.
Align the base plate of column with the chalk line layout.
Guided by the hole on the base plate of the column, drill the
holes into the concrete slab and use five concrete anchor
bolts to fix it onto the ground. During the drilling process,
ensure no movement of the column from the chalk line
(Fig.5).

Notes:
Use sharp
Φ 19mm concrete drill-bit to drill the
holes. Don’t ream the hole or allow the drill to
wobble. Use proper tool to remove the dust from
the hole. The depth of the hole is the same as that
of the anchor bolt. Insert the anchor bolt and make
the washers lean against the base of the column. If
shimming is required, enough thread must be left.
When fastening the anchor bolt, only use the
(torque) wrench, and don’t use impact tool for
fastening.

Insert proper shims under the base of column if
necessary, making the columnvertical.
Note: The thickness of shims shouldn’t exceed
5mm.
。
To get the correct and safety installation, please follow
the following installation steps.
zWear the safety goggles.
zUse hard alloy drill-bit.
zDon’t use the drill-bit with wearing exceeding the
tolerance.
zThe drill and concrete surface should be kept
perpendicular.
zLet the drill work itself. Don’t apply the extra force, and
don’t ream the hole or allow the drill to wobble.
zThe drilling depth of the hole is based on the length of
anchor bolt. The distance from the bolt head to the
concrete ground should be more than twice of the bolt
diameter.
zRemove the dust from the hole.
zGently tap the bolt into the hole, till the washer rests
against the base plate of column.
zTighten the bolt.
5.2.4 Install the floor plate
Position the offside column atthe designated chalk line
location, carefully making the base align with the chalk line
layout. Insert the floor plateinto the gaps of the two columns.

Working principles of hydraulic system:
When the button is pressed to start the motor on the power
unit, the motor 2 will be actuated to put the oil pump 1 into
motion; and oil will be sucked from the oil tank and sent to
cylinder 10 forcing the piston move upward. At this time, the
safety vale 5 is at the “Closed” position. (The pressure is
well adjusted before leaving the factory to ensure the rated
capacity. However, when the system pressure exceeds the
limit, the oil will automatically overflow). When the start
button is released, the oil supply will stop so as to stop the
lifting operation. For lowering the carriage, first start up the
motor to raise the carriage a little, pull the steel ropes on the
two carriages to disengage the safety locking status; and
then press the manual lowering handle valve 6 to lower the
carriage.
