Hänchen clamping devices:
RCH - the clamping unit for arresting the rod of hydraulic presses, injection moulding machines, …

For use, for example, in hydraulic presses and in injection moulding machines, the Ratio-Clamp® type RCH is available.

This clamping device meets the requirements of the Berufsgenossenschaftliche Zentrale für Sicherheit und Gesundheit – BGZ, Fachausschuss Eisen und Metall III, Düsseldorf (Health and Safety Centre of the Employers' Liability Association, iron and metal section III, Düsseldorf).

• The holding forces are at least twice the weight of the load to be carried.
• The locked status is sensed by an inductive proximity sensor and displayed. The sensor operates without making contact and is thus practically free from wear and tear.
• The proximity sensor is equipped with an additional diagnosis output to enable it to monitor its own functions.
• The clamping unit is intended to be used to lock during a machine downtime.

Federal German law (BG) requires that the user ensures that the Ratio-Clamp® RCH clamping unit model is installed in compliance with the requirements prEN 693 or DIN EN 201 and that control technology measures are taken, which will prevent the clamping unit from releasing prematurely (before the load is supported on the pressure column) and which implement a solution through which the holding force can be inspected when in installed status. This is the somewhat down-to-earth requirement. Next to the providing the user with the catalogue range of products we at Hänchen are only too glad to offer our know how and experience with regard to clamping units in their planning and configuration.
