Clamping device Ratio-Clamp® hydraulic clamp from Hänchen

At the very latest when a power failure (intentional or not) or a malfunction occurs and the safety of man and machine needs to be ensured, Ratio-Clamp® from Hänchen comes into its own.

Boasting a retention force of up to 450 kN, the clamp hydraulic holds the piston rod in whatever position it is in at that particular moment. Without having to rustle up some extra power (no extra energy) and for an unlimited period of time. The clamping device Ratio-Clamp® is approved by the German Technical Inspection Agency (TÜV). Nor does the development of specific solutions (larger rod diameters, intermediate sizes, greater clamping forces...) pose a problem to the Hänchen specialists.

Hänchen is particularly proud of its RC-H model. Following a request from the Health and Safety Centre of the Employers' Liability Association (BGZ iron and metal section III, Düsseldorf), Hänchen developed the new safety clamping hydraulic Ratio-Clamp® under extreme conditions for use with hydraulic presses and injection moulding machines.

The possibilities for your application:
Rod-Ø from 10 - 140 mm, clamping forces from 1 - 450 kN.
Other dimensions on request.
