How the Hybrid Excavator System Works

The Cat® 336E H Hybrid Excavator uses a new hydraulic hybrid technology developed by Caterpillar to capture and reuse energy. The benefits include lower fuel costs, reduced exhaust emissions and a smaller carbon footprint—all without any compromise in production, reliability, durability or operability in all applications.

To achieve these benefits, the design of the 336E H is relatively straightforward, using three building block technologies:

  1. Conserve fuel with engine power management via the Cat Electronic Standardized Programmable (ESP) pump
  2. Optimize performance using restriction management via the patented Cat Adaptive Control System (ACS) valve
  3. Reuse energy via the hydraulic hybrid swing, which captures the excavator's upper structure swing brake energy in accumulators and then releases the energy during swing acceleration

Bottom line is the hydraulic hybrid system is a simple, reliable, and cost effective solution that will help you significantly reduce your cost per ton. Learn more about how the system works by viewing the infographic.
