Parker Hannifin RunWise Drivelines in Autocar E3 Refuse Trucks

South Florida’s Miami-Dade County has ordered 29 additional Autocar E3 refuse trucks with the fuel-saving RunWise brand series hydraulic hybrid driveline from Parker Hannifin. Miami-Dade was an early adaptor of the technology, helping prove efficiency gains as great as 51%.

Miami-Dade helped prove Parker Hannifin’s RunWise hydraulic hybrid technology, which is now a commercial reality on Autocar E3 refuse trucks.

Funding from the U.S. EPA of $100,000 per truck to offset the incremental cost of the vehicles was used for 15 trucks ordered through General GMC of West Palm Beach. The other 14 units were ordered at full price – approximately $300,000 per vehicle – through Palmetto Ford of Miami.

‘Investing Their Own Money’

“We have invested significantly in the development of this technology and to see its benefits be proven out in the marketplace is very rewarding,” Parker Hannifin hydraulics group president Jeff Cullman said in a release. “Miami-Dade has seen some tremendous results with their test fleet and we are pleased they have made such a strong commitment to the technology with this large order.

“While they were able to secure federal EPA funding for half of this order, investing their own money demonstrates the positive economics and payback on the technology as a stand-alone purchase,” Cullman said.

Miami-Dade used EPA National Clean Diesel Campaign money. RunWise is the only drivetrain technology on the agency’s Emerging Technologies list, Parker says.

“We’ve been very pleased with the overall performance of the vehicles with RunWise technology,” Miami-Dade fleet management director Danny Diaz says in the announcement. “The savings we are seeing is significant when you look at the long-term with these hybrid trucks.”

All of the diesel-fueled hydraulic hybrid trucks for Miami-Dade have Heil side-loading bodies.

Palmetto Ford has also won a state bid allowing other Florida municipalities to piggy-back on the Miami-Dade order.

Beyond brake energy recovery capabilities and reduced noise levels, Parker says, the Autocar trucks with the RunWise “commonly demonstrate annual fuel savings in the range of 35-50% (equivalent to a 50-100% improvement in fuel economy measured in miles per gallon) with the hybrid drive system for the automatic side loader, reusing as much as 71% of the vehicle’s braking energy.”

In addition to Miami-Dade, the trucks are in operation in Hialeah, Fla. and Miami, in Seymour, Ind. and in Austin, Texas.

Two Autocar E3 trucks with the Parker Hannifin RunWise hydraulic hybrid driveline for Manteca, Calif. (F&F, July 17) were delivered this week and are being prepped for service, says Brian Rottweiler of Western Truck Center in Sacramento. They are the first in the state.
