Hänchen's Ratio-Clamp® offers safety while saving energy costs. Thanks to its sophisticated functional principle, the clamping device features some fundamental advantages when compared with other locking systems:

- clamps all round rods
- immediate fixation of the rod
- direction-independent load-bearing
- clamps without energy supply
- safe even in extreme conditions such as heat or cold
- special solution: up to 2.000 kN for rod Ø of up to 300 mm

Functional principle of the clamping device of a gantry milling machine

Ratio-Clamp® rod locks works mechanically by using frictional contact: The power is directed through springs to a clamping sleeve which holds the rod radially using friction. The load capacity of the fixation is not influenced by the direction. The hydraulic releasing pressure moves the locking piston against the spring power to unlock the clamp - the rod can be moved in both directions. When the hydraulic pressure drops, the power stored in the springs is released, and the rod is locked.


Hydraulic clamping device Ratio-Clamp® is assigned to following product groups:
