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 machineRatio-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 c ...
