As per the latest RID regulations, wagons transporting dangerous goods that are already in use must be able to absorb at least 500 kJ per wagon end, while newly built wagons must be equipped to absorb no less than 800 kJ per wagon end. The purpose of these measures is to ensure adequate protection to accidental impacts at speeds over 12 km/h. To meet these regulations, existing wagons are fitted with crash buffers min. 250 kJ while new wagons carry crash buffers min. 400 kJ.

Most wagons – over 90% – are currently fitted with standard 30 kJ A category buffers. Based on our extensive experience, we believe all wagons should be protected at accidental impacts at speeds over 12 km/h, and not just the ones transporting dangerous goods. Current prices for crash buffers, however, discourage wagons owners from utilizing crash buffers unless RID specifically requires to do so – which is the very issue addressed by INNOVA’s revolutionary 150kJ Crash Buffers.

The INNOVA category A buffer, in its 150kJ constructive variant, provides a cost-efficient solution to the dilemma whether all wagons should be upgraded to crash buffers.

INNOVA’s 150kJ buffer, developed and manufactured by INNOVA Systems & Technologies, has a capacity in excess of 150 kJ in dynamic regime: this translates to 5 times more than a standard A category buffer, and twice as much as a C category buffer. Live impact tests have, in fact, recorded over 200 kJ energy absorption per buffer.

The price of this 150kJ buffer is, however, comparable to that of the standard A category.

The INNOVA crash buffers 150 kJ are equipped with A cat. thermoplastic / polymer shock absorbers (i.e. MINER TecsPak, Durel DP 30).

The buffer deformation comprises two stages:

– elastic deformation, observed at impact speeds under 12 km/h and forces not exceeding 1.5 MN;

– elastic + plastic deformation occurring at speeds exceeding 12 km/h and forces over 1.5 MN.
