There are 6 different Sciherheitsvorrichtungen.
Purpose of the safety
device What it of is produced and
where it is to be found Effect of the device on the
main vehicle lift Effect of the device on the
auxiliary lift
Signaltongeber zum Schutz
der Füße This device consists of a sensor which is
near the underside of the main vehicle lift,
and an acoustic signal.
The Senkbewegung of both
Auffahrschienen is interrupted, as soon
as these are only about 150 mm about
the bottom.
To continue the Senkvorgang, loosen for
one moment the key "main vehicle lift
lower" and press the key then once more.
Then the device gives a discontinuous
acoustic signal of itself.
An acoustic discontinuous signal is to be
heard during the sinking of the
absorption. The Senkbewegung is
interrupted if the absorption only about
150 mm is removed from both
Auffahrschiene. To continue the
Senkvorgang, loosen for one moment
the key "auxiliary lift lower" and press
the key then once more.
Latch device This mechanism consists from:
in the main vehicle lift:
- an attached arrester rod and a
safety cam on every cross beam
side, as well as an arrester rod in
every column.
in the auxiliary lift:
- a locking handle and an arrester rod
on every piston
The locking handle and the arrester
rod prevent accidental lowering (in a 100
mm of height area) in case of a
mistake in the hydraulic cycle or an
Unterbechung in this cycle.
Accidental lowering prevents the
Sicherheitsnocke on account of a sly
absorption tackle.
The locking handle and the arrester
rod prevent accidental lowering (in a
100 mm of height area) in case of a
mistake in the hydraulic cycle or an
Unterbechung in this cycle.
Electronic height control
device This device consists of a photoelectric
cell on one of the absorption of the
auxiliary lift and a reflector in the other
absorption.
This device stops the movement of both lifts, as soon as between both absorption
(auxiliary lift) a height difference of more than 50 mm appears or is the height of
the runways (vehicle lift) more than 150 mm.
Hydraulic safety device The device consists of a boiler safety
valve in each of both hydraulic
cylinders of the vehicle lift.
This device should slow down the Absenkgeschwindigkeit of both vehicle lifts, if
in the hydraulic line a leakage originates. The valve was so stopped that the
Senkvorgang can be maximum 1.5 times faster than with normal speed.
Protection mole place of
the fingers This device consists of a signal strip
(yellow / black) on the external
scissors of the auxiliary lift.
These strips point to the danger of the
Quetschens of the fingers if the
scissors are lowered again.
Electric device for the
control of the ropes This device passes of a switch "floppy
rope" and a switch "sly rope" at the end
of every cross beam.
The switch "floppy rope" stops the sinking of the ramp, if one of the ropes
becomes loose.
The switch "sly rope" stops all movements of the main vehicle lift and raising the
auxiliary lift, as soon as one of the cables tears or becomes extremely loose.
Then an acoustic, discontinuous signal shall be heard.
