Mack Trucks Unveils Fully Electric Mack® LR Refuse Demonstration Model
Mack Trucks unveiled its Mack® LR battery electric vehicle (BEV) at WasteExpo 2019, in Las Vegas last May. Combining the refuse industry-leading design of the Mack LR model with a fully electric Mack drivetrain, the demonstration model will begin real-world testing in 2020 in the demanding operations of the New York City Department of Sanitation (DSNY).
“The Mack LR BEV is the latest example of Mack’s leadership within the refuse and recycling industry,” said Jonathan Randall, Mack Trucks senior vice president, North American sales and marketing. “Built on our decades of experience in powertrain innovation, the electric LR delivers a powerful yet quiet, zero-emission solution designed to tackle one of the most demanding applications in one of the largest cities in the world.”
The Mack LR BEV is powered by Mack’s integrated electric powertrain consisting of 2 130-kW motors producing a combined 496 peak hp and 4,051 lb ft (5,500 Nm) of torque available from zero RPM. Power is sent through a 2-speed Mack Powershift transmission and put to the ground by Mack’s proprietary S522R 52,000 lb rear axles. The Mack LR BEV features a copper-colored Bulldog hood ornament, signifying that it is an electric vehicle.
All of the LR BEV’s accessories, including the hydraulic systems for the Heil DuraPack 5000 body, are electrically driven through 12 V, 24 V and 600 V circuits. Four NMC lithium-ion batteries (lithium-nickel-manganese-cobalt-oxide) are charged via a 150 kW, SAE J1772-compliant charging system.
DSNY is the ideal choice to test the first LR BEV model in a real-world application. It is the world’s largest sanitation department, collecting more than 10,000 t of refuse and recyclables each day. DSNY is also a sustainability innovator and has initiated several programs designed to reduce waste sent to landfills, as well as cut emissions.
Even as electromobility technology and supporting infrastructure continues to develop, refuse and recycling collection represents an ideal application for BEVs because of the potential to deliver the most value to customers. Collection vehicles operate on predetermined routes and return home every off shift, helping eliminate concerns about range and finding a location to charge. The frequent starts and stops, which can occur thousands of times per shift, also provide a significant regenerative braking opportunity to recapture energy.
Fully electric trucks like the Mack LR BEV also produce significantly less noise, enabling nighttime operation, a particularly attractive option for refuse operators in urban environments.
