6.11 risks for unauthorized uses
Fig. 14
The presence of unauthorized persons next to the lift and
on the platforms is strictly forbidden during lifting as wellas
when the vehicle has been already lifted.
Any use of the lift other than that herein specified can cause
serious accidents to people in close proximity of the machine.
6.12 Safety device specifications
the lift is provided with safety devices which grant the user the maximum security the
event of failure.
Specifically, the machine is equipped with four distinct safety devices:
- Mechanical device
: this device is essentially composed of a claw and a rack, and im
-
mediately arrests the sudden descent of the lift (within 100 mm) in the event of hydraulic
line failure or a blow-out in the circuit. Therefore this very important device must always
be kept in perfect efficiency and any tampering or removal is forbidden. It is pneumati
-
cally operated.
- Hydraulic device
: this consists of a counterbalance valve installed on the outlet of the
lifting cylinder, which impedes sudden lift descent in the event of hydraulic line failure.
This valve is calibrated to limit the descent speed of the lift to 0.45 m/s (lower than the
limit specified by applicable law of 0.5 m/s)
- Runway misalignment prevention device
: the dual torsion bars included in the structure
prevent misalignment between the two runways from ever exceeding 50 mm.
- Anti-crushing device
: on the floor mounted version, the protective pipe protects against
crushing by preventing feet from entering the danger area.
On recessed versions, crushing is prevented by an audible warning signal.

only skilled technicians, appointed by the manufacturer, or by
authorized dealers, must be allowed to carry out installation.
Serious damage to people and to the lift can be caused if instal-
lations are made by unskilled personnel.
Before compressed air connection, fill in the hydraulic cylinders
with oil.
