UNI Buffers Vetter Krantechnik

UNI buffers by Vetter are universal travel limiters, perfectly suited for limiting the movement of manual and electric trolleys. Their innovative design enables extremely fast installation without welding, drilling or grinding—simply bolt the buffer onto the beam for instant positioning and adaptation to any application. UNI buffers effectively restrict travel, reliably position hoists at specified locations and protect against uncontrolled rolling, also serving as shock absorbers in case of minor collisions. The product is fully universal—compatible with all hoist brands (up to 10,000 kg capacity) and can be mounted both on the top and bottom flange of the beam, for shelves 91–300 mm wide and 8–25 mm thick. Buffers are supplied in practical pairs.
