Caterpillar Caterpillar
The Cat 336E H excavator uses a new hydraulic hybrid technology developed by Caterpillar. The 336E H has all of the same powerful advantages of the 336E (which was introduced in 2010) with the biggest difference between the two models being even greater fuel efficiency — up to 25 percent savings. To achieve added fuel savings, the design of the 336E H uses three building block technologies that: 1) Conserve fuel with engine power management via the Cat Electronic Standardized Programmable (ESP) pump, which smoothly transitions between the hydraulic hybrid power sources, engine and accumulator; 2) Optimize performance using restriction management via the patented Cat Adaptive Control System (ACS) valve, which intelligently manages restrictions and flows to seamlessly control machine motion with no loss of power, and to ensure operators experience no difference in control, hydraulic power or lift capability; and 3) Reuse energy via the hydraulic hybrid swing system, which captures the excavator’s upper structure swing brake energy in accumulators and then releases the energy during swing acceleration.
