Packing, Transport, Storage
3.1 Packing
The packing of the lift is delivered in following components:
• No. 2 base units, each one with a runway equipped with 2 hydraulic cylinders
• No. 1 jack beam with an air pedal pump
• No. 1 control unit and containing hydraulic unit, hydraulic hoses, air hoses,
anchor bolts, rubber blocks and the technical files.
• No. 2 turntable recess covers
• No. 2 drive-on ramps, 2 drive-off ramps, and 4 hose protective covers if
the lift is ordered for on-floor installation
(If requested, optional accessories are available to satisfy each customer’s
requirements).
3.2 Lifting And Handling
When loading/unloading or transporting the equipment to the site, be sure to
use suitable loading (e.g. cranes, trucks) and hoisting means. Be sure also to
hoist and transport the components securely so that they cannot drop, taking
into consideration the package’s size, weight and center of gravity and it’s fragile
parts.
In Figure 1 there are the correct indications for the lifting of the runways:
Hoist and handle only one package at a time.

3.3 Storage And Stacking Of Packages
Packages must be stored in a covered place, out of direct sunlight and in low
humidity, at a temperature between -10°C and +40°C.
Stacking is not recommended: the package’s narrow base, as well as its
considerable weight and size make it difficult and hazardous.
3.4 Delivery And Check Of Packages
When the lift is delivered, check for possible damages due to transport and
storage; verify that what is specified in the manufacturer’s confirmation of order
is included. In case of damage in transit, the customer must immediately inform
the carrier of the problem.
Packages must be opened paying attention not to cause damage to people (keep
a safe distance when opening straps) and parts of the lift (be careful the objects
do not drop from the package when opening).

Product Description
4.1 Lift Description (Ref. Figure 2)
This lift has been designed for the lifting of motor-vehicles for wheel alignment
and maintenance. The lift can be mounted either on surface or in pit (flush
mounted).
The maximum lifting weight is as specified on the serial plate.
All mechanical frames, such as platforms, extensions, base frames and arms
have been built in steel plate to make the frame stiff and strong while keeping a
low weight. The electro hydraulic operation is described in detail in chapter 8.
Figure 2 – Lift

Product Description 13
12AWFSL
This chapter describes the lift’s principal elements, allowing the user to be
familiar with the machine. As shown in figure 2, the lift is composed of two
runways: P1(1) and P2 (2) with two wheel free jacks (3), anchored to the
ground by means of its base (4). At a special request, two jack beam (5) can be
supplied and operated by an air-hydraulic pedal pump.
Runways are linked to the base by means of a scissors lifting system. The lifting
system of each runway is composed of scissor arms (6) and a hydraulic cylinder
(7). Turntable recess cover (8) is supplied with the lift in case for non-alignment
purpose. Lifting and lowering motion of lift and wheel free jacks is carried out by
operation of a control unit (9) placed next to the lift.
The leveling system of the lift is carried out manually by operation of the leveling
cocks in the power unit. The mechanical safety operating by a pneumatic
cylinder (10) is built under each runway and wheel free jack for engagement and
release. Two limit switches are installed in the P1 base: for top position limit and
for the safety height limit.
4.2 Operation
Lift lifting is carried out by the hydraulic unit which acts upon the cylinders.
The platforms are raised simultaneously owing cross feeding of the hydraulic
cylinders. Lowering, even though electrically controlled, is carried out by the
weight of both the platforms and the load lifted. Lowering motion of the wheel
free jacks with load less can be sped up by means of pneumatic action in the
chamber of its slave cylinder. The hydraulic system is protected by a max
pressure valve thus preventing pressure from exceeding the maximum fixed
safety limit.
Lifting and lowering motion of the lift is controlled by the push buttons on the
control panel. The synchronization of the platforms is guaranteed by a master/
slave circuit. Whenever the lift has to be lowered to the ground and the lowering
button is pressed, the lift will stop at about 18” from the ground. In this way, the
operator must verify that neither persons nor objects are within the safety area.
If so, the final lowering button can be pressed and the lift be lowered. A beep
sound is heard during the last travel.
