Clamping Unit Safety Catcher

The safety catcher is a high-performance clamping unit designed for vertical axles, providing reliable fall protection and preventing uncontrolled lowering or sinking of machine components. It operates on a self-reinforcing mechanical locking principle, securing round rods in any position without continuous energy supply, and is suitable for both compressive and tensile loads. In the event of standstill, power loss, drive failure, or emergency conditions, it automatically locks to hold the load safely and can be released via hydraulic or pneumatic pressure. Widely used in presses, machine tools, robotics, and lifting systems, the safety catcher ensures maximum operational safety for both people and equipment, with optional sensor integration for position monitoring and DGUV-Test certified designs available. DGUV-certified safety With DGUV Test certification, our safety catcher is an approved safety component, e.g., for: + Hydraulic presses (EN ISO 16092-1/-3) + Injection molding machines (EN ISO 20430) Addition to the proven Ratio-Clamp® + Ratio-Clamp®: for high-precision clamping of round rods during the process. + Safety Catcher: for uncompromising securing of vertical axles in an emergency. This ensures you to get the right clamping unit for every application – with the trusted quality you expect from Hänchen.
