Safety Devices
•
Synchronisation connection
The lifting units are connected to a synchronous shaft via the toothed
racks. This limits the height offset between the two piston rods to a
maximum of 50 mm.
•
Dead man control
Each pushbutton is only active as long as it is pressed (dead man control).
When the corresponding buttons are released, the raising and lowering
movements are immediately interrupted.
•
Emergency stop
The main switch on the switch box of the lift is also an emergency stop
switch. An emergency stop switch is located on the optional cable remote
control.
•
Pressure relief valve
The hydraulic power unit has a pressure relief valve. The pressure relief
valve is factory set and limits the hydraulic pressure within the lift.
•
Seat valves
All valves of the lift are designed as seat valves and are closed in the rest
position. In the event of a leak, controlled lowering is still possible; in the
event of a power failure, the lift will not lower itself.
•
Pinch point protection
The lift has an automatic stop at a distance of at least 120 mm between the
support and the workshop floor (pinch point protection). Pressing the
“
DOWN
”
button again lowers the lift with an acoustic signal.
•
Support arm lock
The support arm lock automatically locks in the raised state, so that it is not
possible to change the position of the support arms when loaded.
•
Ceiling light barrier
Optionally, the lift can be equipped with a ceiling light barrier. The overhead
light barrier prevents a lifting movement beyond a defined range.
