If there was ever a vehicle you wouldn’t expect to be near silent and zero-emissions, it would have to be the Mack Truck.
The Big Daddy of trucks, the ones that announce themselves from blocks away with raucous engine roars and bone-shaking vibrations. Powerful, intimidating, stepping up to do the toughest and most demanding jobs, like hauling trash out of neighborhoods. That’s the Mack truck. Specifically, in this case, the Mack LR: the industry-leading powerhouse in the refuse and recycling space.
Mack just pulled into town with another tough hombre, a contender that’s the strong, silent type and more relevant for our times. Revealed at WasteExpo 2019, the Mack LR BEV (battery electric vehicle) keeps the handsome and formidable design of the LR and powers it with a zero-emissions electric motor.
Under the hood the Mack LR BEV packs an integrated electric powertrain consisting of two 130-kW motors producing a combined 496 peak horsepower and 4,051 lb-ft of torque, available from zero RPM. Power is sent through a two-speed Mack Powershift transmission and put to the ground by Mack’s proprietary S522R 52,000 lb rear axles.
The LR BEV takes it to the finish line with the electric theme. All of its accessories, including the hydraulic systems for the Heil DuraPack 5000 body, are electrically driven through 12V, 24V and 600V circuits. Four NMC lithium-ion batteries (Lithium Nickel Manganese Cobalt Oxide) are charged via a 150kW, SAE J1772-compliant charging system.
And here’s the coolest part: the Mack LR BEV sports a copper-colored Bulldog hood ornament to indicate it’s an electric model. Although its less booming presence, zero smoke-choking emissions and much quieter operation give it away.
The Mack LR BEV will do its first field test in New York City in 2020. The world’s largest sanitation department, New York City Department of Sanitation (DSNY) employs 10,000 people and collects more than 12,000 tons of trash and recyclables per day. Per day!
If the Mack LR BEV can stand up to the demanding requirements and mean streets of the DSNY, then it’s gone from a contender to an undisputed winner.
