The main body of the Yellow Clamp Series PISTON CLAMP has an integrated pressurisation mechanism enabling it to exert the pressure necessary for clamping. As a result, no external hydraulic power unit, and therefore no electricity, is required. The easy-to-use device is also equipped with a simplified internal hydraulic structure, which made it possible to reduce the number of parts and simplify the manufacturing process. The jury was impressed by the “skilful implementation of a clear idea that not only meets technical requirements but also expresses a great sense of responsibility”.
