Fully electric Mack bin lorries will go on trial in New York next year to help cut emissions in the city

Iconic US truck company unveils fully electric battery operated refuse collection vehicle to go on trial next year in New York City.

Think of Mack Trucks and you’ll probably image trucking gone large, the stuff of American movies, chrome plated smoke stacks and an engine that could power a small ship. You’re less likely to associate the brand with battery power and clean air but that stereotype might soon change.

The company used the recent WasteExpo event to reveal its Mack LR battery electric vehicle (BEV) with a fully electric power train and designed for inner city waste collection. Still at the prototype stage, the new vehicle will commence trials next year with the New York City Department of Sanitation (DSNY).

The Mack LR BEV integrated electric powertrain consists of two 130kW motors producing a combined 496 peak horsepower and 4051 lbft of torque available from zero RPM. Power is sent through a two-speed transmission and put to the ground by Mack’s proprietary S522R 52,000-lb. rear axles.

All of the LR BEV’s accessories 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.

Challenging Testing

DSNY is the world’s largest sanitation department with 10,000 employees collecting more than 12,000 tons of refuse and recyclables each day. DSNY is also a sustainability innovator and has initiated several programmes 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. Collection vehicles operate on predetermined routes and return home at the end of every 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.

In addition, fully electric trucks produce significantly less noise, enabling nighttime operation, a particularly attractive option for refuse operators in urban environments.
