3.10 Behaviour in Emergencies

An emergency situation exists when
● power suddenly fails (device switches off),
● the vacuum pressure drops below -0.22 bar to the red section on the scale of the vacuum gauge.
Lower the load immediately if possible. If this is not possible, immediately leave the dangerous area near
the load, since it will be dropped from the device.

3.11 Checking the Safety Devices

The lifting device is equipped with
following safety devices:
Checking the Vacuum Gauge
and the Warning Device
Checking the Vacuum Hoses
and Hose Clamps:

Safety
● vacuum gauge with red danger zone
● warning device, audible (optional)
Check these devices at the beginning of each shift (when operating in shifts) or
once a week (when operating continually).
Warning device monitors the operating vacuum and power failure

Switch on the lifting device.

Place the lifting device on a stone slab or similar material and apply vacuum.
Caution: Simply apply vacuum to attach the suction pads to the stone slab. Do
stone slab
not lift the , since it may be dropped during the test!

When the vacuum has built up, lift the edge of a suction pad to create a leak.

The reading on the vacuum gauge decreases. When the vacuum
drops below red danger zone, the warning device must sound.
Check all vacuum hoses and clamps for proper mounting and tighten the clamps
if necessary.
See "Testing for Leaks"" in chapter "Maintenance"
Correct any faults before using the device. If faults occur during
operation, switch the device off and correct the faults before
continuing work with the device.
