A Thousand Energy-Saving Opportunities

Each time an excavator slows or stops, kinetic energy is lost during braking. Caterpillar engineers realized if they could capture that energy, store it temporarily and redeploy it upon swing acceleration, the result would help customers gain greater fuel efficiency and cost savings. Our engineers have done just that with the revolutionary new Cat® 336E H hybrid excavator.
