Buffer stops

Our gas-hydraulic buffers installed in the buffer stops are engineered and designed to absorb the kinetic energy created from high velocity and high force impact by the rolling stock, ensuring a controlled deceleration. Made from high strength steel, machined and precision engineered to meet the toughest tasks and standards for any situation. Crash absorbing buffers from Dellner are the most common and trusted buffers in train-, tram-, LHV- and metro industries for safety and protection.

Preventing rolling stock from running off the track, protecting people and infrastructure.

There are different types of buffer stops and each individual case also has local conditions that need to be met. With our advanced energy absorption simulation software our engineers simulate and pre-calculate the units before designing and manufacturing customized buffers for each application.

Drawn from the railway industry with the highest industrial demands and standards, we have developed our Hybuff G-series buffers. Our gas-hydraulic buffers are now the most used and requested units in the world from the largest rolling stock manufacturers. When our buffers are installed for collision and impact protection you have peace of mind.

The HYBUFF G-series buffers come with optimum corrosion protection included as standard − right up to ISO EN 12944 C5M, which is tough enough for harsh sea environments. They also have Ni-compound treated plunger, a stainless-steel end cap and a front or back mount as standard, with other customized solutions available. All buffer models have been tested for extreme conditions with the harshest impacts, collisions, salt sprays and temperatures to ensure functionality and expected lifespan is met or exceeded. By other means – Quality guaranteed
