New Caterpillar excavator features hydraulic, not electrical, hybrid technology
Caterpillar Inc. is at the forefront of hybrid technology in large machines, exemplified in its new 336E-H line of hybrid hydraulic excavators. These new excavators first rolled off the line in 2013 and are the first of their kind to convert captured energy into hydraulic instead of electric power. The new hydraulic hybrid system integrated in the 336E-H can handle the same amount of work as the powerful 336D machine, but using 33% less fuel.
The hybrid excavator was recently featured in a local news story by the Peoria Journal Star earlier this year.
The first film in the series, Paint by Numbers, tells the story of how Honda engineer Shubho Bhattacharya was inspired to develop technology to reduce the energy needed to operate the auto body-painting system at Honda's manufacturing plant in Marysville, Ohio. Auto body painting accounts for the most energy use in Honda's production process. With the help of his fellow associates, Bhattacharya conceived Honda's Intelligent Paint Technology, which has cut Honda's North American manufacturing CO2 emissions by about 10,000 metric tons per year.
