SAFETY DEVICE
SPECIFICATIONS
The lift is provided with safety devices which grant the user the maximum security the
event of failure.
The safety devices are the following:
Mechanical device: this device is essentially composed of a claw and a rack (see fig. 11), and
immediately stops the sudden descent of the lift (within 100 mm height) 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 pneumatically operated.
11
Hydraulic safety : this consists of a counterbalancing valve (see fig. 12) positioned on the
discharge of the lifting cylinder, which has the function of stopping the sudden descent
of the lift in the event of the hydraulic hoses breaking. The valve is calibrated so that the
lift’s descent speed will be lower than the value set by the regulations in force.
