III. Environmental hazards
The operation of clamping or gripping equipment partly requires the use of various media for lubrication, cooling,
etc. In most cases these media are supplied to the clamping equipment through the hose lines or pipelines. The
most frequently used media are hydraulic fluid, lubricating oil or grease and coolant. When operating the clamping
equipment, these media have to be handled with care so that they do not get into the ground and/or into the water.
Warning: Environmental hazard!
This applies in particular to the following:
For assembly/disassembly as residual amounts may still be in the pipes, piston chambers or oil drain
screws,
To porous, defective or incorrectly fitted seals,
To lubricants which escape from and/or are ejected from the clamping equipment during operation for de-
sign reasons.
For this reason, these escaping substances should be collected and re-used or disposed of in accordance with
applicable regulations.
IV. Safety requirements of power gripping devices:
1. The gripping device must not be allowed to move until the clamping pressure has been reached in the grip-
per and the clamping force is within the permissible working range.
2. The tension may be relieved only when the gripping device is at a standstill.
3. In the event of the clamping energy failing, a signal has to shut down the machine immediately.
4. In case the clamping energy fails the workpiece has to remain safely gripped.
5. In the event of a power failure and subsequent return of power, no changes of the switch position may oc-
cur.
V. Safety information:
1. Do not move any parts by hand if the energy supply is connected.
2. Do not reach into the open mechanism or between the gripping jaws.
3. Disconnect the energy supplied when carrying out any assembly, conversion, maintenance
and setting work.
4. Carry out servicing, conversion and mounting work outside the danger zone.
5. During assembly, connection, setting, commissioning and testing work it must be ensured that
the unit cannot be actuated accidentally by the fitter or other personnel.
6. Protective covers which comply with the EC Machine Directive must be provided when in-
stalling all handling modules.
7. Falling or catapulted items may present dangers. Precautions must be taken to prevent items
falling or being catapulted.
8. The care and maintenance intervals must be observed.
9. Grippers which clamp with spring force or have a gripping force guard with springs are spring-
loaded. The springing contact star is also spring-loaded. Therefore special care is required for
dismantling them.
10. Top jaws, particularly on grippers with a gripping force maintenance unit, must be designed in
such a way that a gripper reached one of the limit positions when it is depressurized so that no
residual energy is released when the top jaws are replaced.
Otherwise the maximum working distances must be taken from the relevant tables.
Furthermore, the safety and accident prevention regulations in force at the place of use are al-
so applicable.
