4.10 Protective equipment

The protective equipment must consist, according to
the safety regulations of the following parts:

4.11 Behaviour in Emergencies

An emergency situation exists when
●
power suddenly fails (device switches off),
●
the vacuum pressure drops below -0.42 bar to the red section on the scale of the vacuum gauge.
Danger
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.

4.12 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:
Checking the Vacuum Reservoir
●
vacuum gauge with red danger zone
●

Check these devices at the beginning of each shift (when operating in shifts) or
once a week (when operating continually).

When the vacuum has built up, lift the edge of a suction pad to create a leak.

Attention
The reading on the vacuum gauge decreases. When the vacuum drops below
–0.42 bar, the warning device must sound.
Check all vacuum hoses and clamps for proper mounting and tighten the clamps if
necessary.
