Ground-Breaking OperationWhat really sets Tramac’s SC Series apart from the competition? Inside every SC breaker, an automatic pressure regulator reduces pressure variations to prevent overheating and extend the life of the breaker. In addition, an inventive hydraulic design ensures the SC never loses power and productivity like nitrogen-assisted breakers.
| Nitrogen-assisted breaker |
| Most nitrogen-assisted breakers’ energy comes from compressed nitrogen. During use, hydraulic flow displaces the piston forcing it upwards. As the piston compresses nitrogen at the top of the stroke, hydraulic flow stops or is diverted, causing a shock to the carrier’s hydraulic system. This built-up pressure pushes the piston downwards. However, as nitrogen leaks with normal use and improper storage, power decreases until the breaker can be refilled. |

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