Hydraulic Clamping Unit – Safety Catcher
The Hänchen Safety Catcher is used for clamping round rods in vertical, gravity-loaded axles. It ensures reliable safety mechanisms for stepless securing of loads at a standstill, as a safety component in case of emergency, or for effective fall protection.
The safety catcher mechanically locks based on a self-energizing principle and supports both compressive and tensile loads. Unlocking is achieved via hydraulic or pneumatic pressure.
Advantages of hydraulic rod locks
The holding load of the safety catcher for machines has a safety factor of at least 2, but does not exceed a safety factor of 2.8. It is certified through the DGUV Test, which confirms that the clamping unit is tested as a safety-related component according to European standards such as EN ISO 16092-1/-3 for presses. It simplifies the risk assessment of the overall machine, as the protective function is officially proven.
Various mounting flanges and sensor technology components are available as accessories. A functional rod with freely configurable piston rod ends can also be configured in Hänchen’s HäKo online product configurator.
