CHAPTER 4 - PRODUCT DESCRIPTION
4.1 LIFT (ref. Figure 1)
The lift has been designed for the lifting of motor-vehicles and for making them stand at any level
between the minimum and maximum height.
The maximum lifting weight, including any additional load on the vehicle, 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.
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 platforms: P1 (1) and P2 (2) each equipped with the
drive-on/off ramps (3) which can be locked to the platforms as extensions, anchored to the ground by
means of bases (4).
Platforms are linked to the base by means of a scissor lifting system.
The lifting system of each platform is composed of N.4 arms: two inferior (5) and two superior (6),
and a couple of cylinders: master (7) and slave (8). The mechanical safety (9) is built on each runway
and can be locked and released by means of the air cylinder.
Motion is transmitted by a lever system, from the cylinders to the lever (10).
Lowering and lifting are carried out by means of a control unit (11), placed next to the lift.
Two limit switches are installed on the P2 base: one for the top position and one for the safety height,
protected by a cover (12).

4.2 OPERATION
Platform 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.
The hydraulic system is protected by a max pressure valve thus preventing pressure from exceeding
the maximum fixed safety limit.
Whenever the lift has to be lowered to the ground and the lowering button is pressed, the lift will
stop at about 16 inches 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 will be completely lowered. A beep sound
is heard during the last travel.
