1 M is the admissible force the mass to be secured exerts on the Sa­fety Lock KRGP.

Against forces in load direction (see Fig. 1) the rod will be totally blo-
cked, the higher the force the stronger the grip. Therefore forces ex­ceeding 2xM may cause damages of the device.

It must be ensured that the dimensions and arrangement of Safety Lock
KRGP in safety-relevant applications meet the requirements of the risk
evaluation (EN 1050) and also comply with any further standards and
regulations applying to the intended use. This is the duty of the system
manufacturer and the user.
2 p is the pressure required to keep released. The permissible wor­king pressure is 10 bar.

3 Regarding safety it is an advantageous feature of the Safety Lock
KRGP, that it normally will not release unless not only pressure is ap­plied but also the load is supported by the lifting drive, thus automati­cally unintended releasing is prevented.

However, this is only true, if the the load exceeds a minimum limit which
depends on the working air pressure. With for example 6 bar pressure
the critical minimum load is equal to F6. Values for other pressure level
will be given on request.

4 Pneumatic operating volume
5 Proximity switch holders are provided for standard proximity swit-

ches M12x1 shielded and with a nominal switching distance of 2 mm.
For easier service, the proximity switch holders have a positive stop

and are preset when deliverd from the factory..
6 Port T is used for pressure compensation (breathing). It is plugged
with an air filter element. If, however, moisture or aggressive media are
present, a hose instead of the filter must be installed to connect the de-

vice with clean and dry atmosphere.
