Launched in the USA last year, the innovative, fuel-saving hydraulic hybrid system captures energy from swing braking and reuses it.

The machine’s engine runs at a lower rpm but retains performance.

Ken Gray, global product manager for large hydraulic excavators for Caterpillar’s Excavation Division, contractors have shown tremendous enthusiasm for the 336E H since the day it was unveiled in the US.

“Customer interest has been off the charts,” Gray said.

“They’re not only reaching out to Cat dealers to learn more about the 336E H, they are placing orders. In fact, we received our first signed orders October 17th, the day after the reveal.”

Gray also said customers want to know about Caterpillar’s plans for expanding hybrid technology to additional excavators.

“We’re getting a lot of questions about what other models will be available as a hybrid, and when,” said Gray.

“While I will not divulge our full hybrid strategy, I will say we will have two additional hydraulic hybrid models, the 336F H and 336D H, on the way.”

Assuming today’s fuel prices and a production application for a 336E H, Caterpillar estimates customers can realistically expect to see a return on their investment for the hybrid excavator model in as little as one year, with 18 months as typical.
