All Tramac by Montabert breakers utilize solely 100% oil pressure for the creation of piston energy. A sealed rubber diaphragm accumulator combined with the pressure regulator which continually adjust a constant percussion pressure independently from delivered flow but also prevent the rubber diaphragm from impacting the accumulator flange.

The energy recovery valve allows a real recovery of piston rebound energy (up to 30%) by recycling a certain quantity of oil directly into the accumulator.
Tramac by Montabert is also well known to be the leader in the variable stroke change technology.

All models from our "V Series" adapt automatically the impact energy to the material resistance. For each blow, a sensor checks the rebound of the piston.

All of these features are part of our new tool-guiding known as TPS (tool protection system) which increase the tool retainer life span, increase the upper and lower bushing life span allow Tramac by Montabert Breakers to offer higher reliability, higher availability and higher performance.

Inside every Tramac by Montabert breaker, an automatic pressure regulator reduces pressure variations, preventing overheating, and extending the life of the breaker. In addition, Tramac by Montabert breakers never lose power and productivity like nitrogen-assisted breakers.

Most nitrogen-assisted breakers' energy comes from compressed nitrogen. During use, hydraulic flow displaces the piston upward, compressing the nitrogen. At the top of the stroke, hydraulic flow stops or is diverted, causing a shock to the carrier's hydraulic system. The built-up pressure in the nitrogen chamber pushes the piston downward. However, as nitrogen leaks with use and improper storage, power decreases, until the breaker is refilled.

In contrast, Tramac by Montabert breakers use hydraulic flow to move the piston up and down. On the up stroke, excess oil is stored in a fully enclosed energy chamber. Once the piston reaches the top of its stroke, high-pressure hydraulic flow is diverted, and forces the piston downward. Towards the end of the stroke, stored oil from the energy chamber is released to complement flow from the carrier and to compensate for the piston's high velocity. Then the cycle repeats for constant power and performance with every blow.
