Mack Trucks made a splash at the recent WasteExpo 2024, where more than 13,500 attendees had the opportunity to check out the newest Mack trucks for the waste and recycling industry. Chief among them was the next-generation Class 8 Mack LR Electric with a Heil automated side loader. Mack says the 100% electric truck provides 42% more energy and increased range between charges thanks to its 376-kilowatt-hour battery capacity.

LR Electric Specs & Benefits

The LR Electric has a gross vehicle weight rating (GVWR) of 66,000 pounds (30,000 kilograms) and a payload capacity of 25,000 lbs (11,300 kg). The truck’s dual electric motors generate nearly 500 continuous horsepower (373 kilowatts) and up to 4,051 pounds-foot (5,492 newton-meters) of peak torque from 0 rpm.

Big Operating Range, Zero Emissions

Operators can expect a 100-mile (161-kilometer) operating range from the LR Electric, which generates zero emissions, requires zero oil changes, and carries zero diesel-related costs. Recharging its four nickel manganese cobalt oxide (NMC) lithium-ion batteries takes roughly 2 hours at 150 kW using an SAE J1772-compliant charging system. The truck’s 2-stage regenerative braking system recaptures energy as operators make the numerous stops that make up their routes.

The MD7 On Display

Mack also showcased an MD7 from its Class 6 and Class 7 medium-duty truck series. These have a flat-back cab and offer wheelbase options from 10 to 26 feet (3 to 8 meters). The MD7 is available in 4x2 configurations with multiple engine and transmission options. The truck appearing at the trade show had a Cummins ISB6.7 engine rated for 300 HP (223 kW) and 660 lbf-ft (895 N-m) of torque.

Mack says the truck, which has a GVWR of 33,000 lbs. (15,000 kg), is ideal for collecting refuse in tight or weight-restricted areas. Owners will appreciate that the MD7 is exempt from the 12% Federal Excise Tax.

Showcasing The TerraPro

Also at WasteExpo was the Mack TerraPro, a compact model ideal for refuse and vocational duties, including those requiring operators to navigate tight neighborhood quarters to perform. Mack says the Class 8 truck’s shorter length and slimmer cab contribute to its enhanced maneuverability and capability to operate in narrow spaces. The version at the show had a Mack MP7 Powerleash engine rated for 355 HP (265 kW) and 1,260 lbf-ft (1,708 N-m) of torque.
