CHAPTER 4 -
MACHINE DESCRIPTION
4.1 Lift (see Figure 2)
The lift has been designed to lift motor vehicles and make them stand at any level between the
minimum and maximum height.
The maximum lifting weight, including any additional load on the vehicle, is specified on the serial
plate of the lift.
All mechanical equipment, such as platforms, extensions, base frames and arms have been built in
metal sheet in order 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, showing its main parts, thereby allowing the user to become familiar
with the machine. As shown in figure 2, the lift is composed of two platforms, platform 1 (1) and
platform 2 (2) anchored to the ground by means of two base frames (3). The platforms are linked to
the base frame by means of a double scissors lifting system. The platforms are 1560 mm long, can
reach a length of approx. 2100 mm with two extractable extensions (4) to allow longer wheelbase
vehicles to be lifted.
The lifting system of each platform is composed of four arms, two lower
(5) and two upper (6) arms, as well as a pair of cylinders, i.e., a primary and a secondary
cylinder. Motion is transmitted from the actuators to the arms through a lever system.
Lift lowering and raising operations are carried out by means of a control unit (8) (fixed to the
ground) placed next to the lift.
A sensor (Encoder) is installed inside the scissors of platforms 1 and 2 to stop the lift at a height of
400 mm.
A sensor (Encoder) is installed inside the scissors of platforms 1 and 2 to stop the lift at the
maximum height.
Drive-on ramps (7) are present at the base of platform 1 and platform 2.
