2.3 SAFETY DEVICES
The tire changer has a number of safety devices designed to
guarantee the upmost safety:
Check valve on the spindle opening hydraulic line
(inside the swivel connector, see fig. B/1). This
prevents the wheel from falling from the spindle if the
hydraulic line is accidentally broken.
Pressure relief valve set at 130 bar ± 10% (see fig.
B/2). This limits the pressure in the hydraulic line and
ensures correct operation of the plant.
Pump motor overload cut-off (inside the electric
enclosure). This cut prevents the motor from burning
out if it overheats.
Check valve on the chuck arm lifting hydraulic line.
It prevents the chuck arm from descending when any
accidental break occurs in the hydraulic line. .
