Mack highlights scope of its waste collection lineup at WasteExpo 2024

Mack Trucks is showcasing the range of its lineup for the waste industry during WasteExpo 2024. Mack will feature the Mack LR Electric, a Mack MD7, and a Mack TerraPro in its booth and will also have two Mack LR electric vehicles in a ride-and-drive in the parking lot of the Las Vegas Convention Center during the show.

The Class 8 Mack LR Electric refuse model offers a 376 kWh total battery capacity for 42 percent more energy and an increased range between vehicle charges. Twin electric motors produce 448 continuous horsepower and 4,051 lb.-ft. of peak torque output from zero RPM.

Four NMC (Nickel Manganese Cobalt Oxide) lithium-ion batteries, charged through a 150 kW, SAE J1772-compliant charging system, power the vehicle and all onboard accessories through 12V, 24V, and 600V circuits. The two-stage regenerative braking system helps recapture energy from the hundreds of stops the vehicle makes each day with an increasing load.

The Mack MD7, a Class 7 model with a gross vehicle weight rating (GVWR) of 33,000 pounds, is exempt from the 12 percent Federal Excise Tax (FET).

Available in 4x2 configurations, the Mack MD7 is ideal for refuse collection in tight or weight-restricted areas and other applications. The MD model also offers a clear back of the cab and top-of-frame rail to make it easier for bodybuilder adaptations. 

The TerraPro model can handle tough applications, whether it's being utilized as a refuse vehicle or as a concrete pumper.
