HYBRID
A hydraulic hybrid drive makes sense wherever braking and acceleration are frequent. And this is always the case when using a tandem roller on an asphalt construction site. Because a conventional engine doesn't work in the optimal range of efficiency when starting up and during vibration initiation. A hydraulic hybrid drive can support it perfectly and efficiently here.
With conventional braking, kinetic energy is dissipated in the form of heat. However, the system used by BOMAG converts this kinetic energy into hydraulic energy that can still be utilised. When braking, oil is pumped from the low-pressure tank into a pressure accumulator. The inflowing oil compresses the gas in the accumulator. The energy thus stored can be flexibly released as needed.
When load peaks occur, the pressure accumulator opens. Escaping oil drives an auxiliary hydraulic motor (hydrostatic piston engine). The result - a power boost! BOMAG is one of the few construction machinery manufacturers to have perfected and brought this system to series production readiness. With one clear objective: BOMAG construction machinery must be efficient and save fuel.
Our construction machines with hybrid technology use braking energy. With each change of direction, it is stored and released again when starting up.
Every job is different: Even for experienced users, every construction site poses a new challenge. Our experts are happy to advise you on the right machine and the optimum technology so that your project comes to a successful conclusion. Arrange for a consultation now.
