In addition, garbage routes present an opportunity for the vehicle’s regenerative braking, in which the operator lifts their foot off the gas pedal to stop the vehicle while the kinetic energy lost during deceleration is converted to stored energy in the battery. The refuse industry, Barraclough said, is a good fit for electric trucks because it runs predictable routes and the vehicles return home every day for charging. The department received its first electric garbage truck in September 2020, when it began testing the vehicle in Brooklyn. In late June, Mack announced that the world’s largest municipal sanitation department, the New York City Department of Sanitation, planned to purchase seven Mack LR Electric models, which will be located in the seven zones of the city. ![]() “With the new technology, the price point is quite a bit higher than its diesel counterpart, and to really get the ball moving here, incentives play a key role in customers buying the trucks,” he said.īut Mack already has seen strong interest in the truck. One way to boost those efforts is for federal leaders to develop incentives to motivate customers to make the switch from a diesel to electric garbage truck, said Scott Barraclough, Mack’s senior product manager for electromobility. That’s something that should catch the attention of most Lehigh Valley residents, especially amid the explosion in local warehouse development and the truck traffic that comes with it, said Andrea Wittchen, president of the Lehigh Valley Sustainability Network. As it is now, greenhouse gas emissions from transportation account for about 29% of the U.S. ![]() The event, sponsored by the Lehigh Valley Sustainability Network, called on Congress to pass a budget with big investments in clean transportation infrastructure. Many people would like to see that timeline accelerated, including several climate advocates who joined Brunius at the Mack plant Thursday. “The transition period - how long that will be - that is sort of written in the stars.” “This truck is the future for the plant, but the question is then the timeline of when we are moving from diesel trucks into electric,” said Brunius, vice president and general manager of Mack’s Lehigh Valley Operations. ![]() And just a few feet behind the truck was Mack Trucks’ Lower Macungie Township assembly plant, which will soon start serial production of the electric truck. He meant that literally: A few feet away sat a blue Mack LR Electric, a fully electric garbage truck that produces no emissions and operates quietly. The first LR electric truck will do its real-world testing with the New York Department of Sanitation starting in 2020.Gunnar Brunius stepped to the podium late Thursday morning and said “the future” was sitting just behind him. Also, the hundreds of stops and starts that a truck might see during a shift gives plenty of opportunity for brake regen, which should help range too. Mack left out the specifics on the LR BEV's expected range, but it's fair to assume that most garbage trucks don't pile the miles on in the same way that a semi truck would. The whole system is powered by four large lithium nickel manganese cobalt oxide batteries that can be recharged at up to 150 kW and 200 amps. The LR BEV uses battery power to drive these systems, including hydraulics. The diesel engine on an ordinary trash truck doesn't just make the wheels spin it also has to run a ton of hydraulics and other systems. It does this with two 130-kilowatt AC motors, a two-speed transmission and some beefy Mack 56,000-pound axles. The model it debuted is based on the LR truck that is already popular with municipalities all over the country only it has a fairly wild battery-electric drivetrain under it that makes a respectable 496 horsepower and a mind-boggling 4,051 pound-feet of torque. ![]()
