A light rail-vehicle buffer that meets the requirements of the EN15551 standard, the UIC 528 leaflet as well as the related leaflets (except the buffer disk size). The shock absorber unit consists of the preliminary absorber featuring disk springs and the main elastomer shock absorber. Both solutions have already proved their infallibility and functional reliability during many years of operation. The buffer is characterized by good working parameters and operational reliability within the temperature range from -40ºC to +50ºC. Free-flowing elastomer retains its properties for many years. The material is also recyclable.
