With the newest innovations in energy absorption technology, KONI offers the widest selection of high capacity buffers in the world.
Our buffers are used as energy dissipation devices installed in automated couplers and draw bars to provide crash protection from frontal and rear impacts caused by vehicle-to-vehicle collision.
Our products bring optimal energy absorption capabilities while also providing increased internal safety. Our state of-the-art testing facilities ensure the integrity of design and product performance.
Buffer development
In order to start the development process, our engineering departments needs the following information, depending on the application:
Requested data for buffer development
» Type of unit & position in the train
» Train details
» Impact configuration (train/train, train/wall...)
» Requested performance
» Acceptable dimensions (Ø, length, weight...)
Requested data for end of track stop
» Vehicle mass (kg)
» Impact velocity (m/s)
» Maximum dynamic reaction force (kN)
» Maximum allowed deceleration (m.s2)
» Configuration of vehicle front
» Available installation space
» Available sliding distance (if applicable)
» Track configuration (rail dimensions)
» Environmental issues (temperature, corrosion, etc...)
Please contact our Engineering Department for a specific analysis of requirements.
Fixed and sliding end-of-track stops required? HI series buffers boast the latest in production technology. The large-bore, high-capacity buffers have been individually designed to decelerate moving loads under a wide range of conditions.
Designed to save resources, silicon fluid (SF) shock absorbers combine the energy absorption and return spring functions in a single unit – without the need for an additional gas or mechanical spring stroke return mechanism.
The design of silicon fluid buffers utilizes the unique compression and shear characteristics of specially formulated silicone elastomer. These characteristics allow the energy absorption and return spring functions to be combined into a single unit without the need for an additional gas or mechanical spring stroke return mechanism.
