The Hänchen hydraulic Ratio-Clamp® is a positive rod clamping safety device. The Ratio-Clamp® is unlocked by hydraulic pressure. In the event of an electrical / hydraulic power loss, the potential energy of the internal Bellville washers load a conical piston, driving it over the friction fingers resulting in securing the load. “ a true self contained safety clamp”.

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 generate 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). Special development of Custom solutions (larger rod diameters, intermediate sizes, greater clamping forces…) pose no problem for 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.
