A strong brand for a unique technology

The proven self-intensifying clamping technology has made a name for itself around the world. This recognition allows us to ensure transparency on the market for clamping devices and linear brakes. SiForce Technology is not just about safety, but also relates to the principle of self-intensifying force.

Optimal safety for people and machinery

Self-intensifying clamping is used mainly to provide unrivalled safety for machinery, and above all persons, around the world by reliably securing large axial forces and loads. Besides absolute reliability, quality and the associated longevity of the clamping heads are the top priorities.

Advantages at a glance

• Release under load is impossible, thereby ensuring safety against unintentional release.
• As long as the closed clamping system is unloaded (secured state), simply pressurizing it is enough to release it (no need to raise the load).
• The loaded clamping head can be released (e.g., after an emergency stop) only after the clamping head has been relieved. Safe load transfer to another system (such as the drive) is therefore automatically ensured. Simply lifting the load is enough to relieve it; no additional force (no “reversing/ retracting”) is necessary.
• Consequently, release is also gentle when used on cylinders.
• Moving upwards is always possible, e.g., to free a trapped person, even when the clamp is closed.
• The clamping system is loaded only when this is really necessary.
• This ensures a long service life (B10D values up to 6 million).
• Safety factor > 2 built in.
• Loads up to 220 kN can be secured pneumatically as well.
