Featuring a particularly high safety reserve and, the hydraulic clamping devices certified by DGUV Test are approved for the use in hydraulic presses according to DIN EN 693, and in plastic injection moulding machines according to DIN EN 201. They meet all requirements of the DGUV Test, the testing and certification authority for lifting gear, safety components and machinery.
Potential dangers from external forces or loads must be taken into consideration if machines are subject to a risk assessment according to DIN EN ISO 13849-1. These dangers must be prevented from causing a hazardous movement of the cylinder. The clamping device Ratio-Clamp® ensures the safety of people, machines and tools in the event of a power failure or system shutdown.
In case of fluctuations, loss or return of pressure energy, the safety clamping device triggers and locks the round rods under an axial load for an indefinite time, without pressure and reliably. For more information about the functional principle, please refer to clamping device basics.
As a safety element, the clamping device is used as follows:
