Mack garbage truck models8/27/2023 Wheelbases are from 173 to 246 inches (440 to 620 cm) and 250 inches (640 cm) with a drop frame.ĭana-Spicer and Meritor supply air brakes, steering systems, driveshafts, and other components.įront axles are rated at 20,000 pounds (9,100 kg). The LR has more frame options than other Mack trucks, with drop frames available. The base rear suspension is a Mack tandem but other axle/suspension types are available. Front axles are on semi-elliptical leaf springs. The RDS is a fully automatic planetary gear transmission with a lock-up torque converter.Ī ladder frame with beam axles is used. Transmission Īllison RDS 6-speed transmissions are used on all models. It develops 329 horsepower (245 kW) and 1,000 pound force-feet (1,400 N⋅m) of torque. The Cummins Westport L9N is a 543 cubic inches (8.9 L) turbocharged inline six-cylinder natural gas engine. It is a 659 cubic inches (10.8 L) overhead cam turbocharged inline six-cylinder diesel engine. The Mack MP7 is the base engine in the LR. In 2020 an all-electric models was available. The LR is available with a Mack MP7 diesel and a Cummins Westport natural gas engine. Most other vendor components are also available but engine choice is very limited. Mack builds their own major components (engines, axles, and suspensions) and promotes an integrated design but all LRs use a vendor transmission. There are locations for a joystick and other controls. This system can also shift the transmission into neutral when it is applied. The service brakes can be electrically applied, allowing the driver to exit leaving them on. Total loaded weight can be up to 72,000 pounds (33,000 kg).Īdvanced electronics are used for engine, chassis, and body controls, as well as maintenance. It has a stand-up right-side (curb) driving position. The cab is mounted very low and forward, allowing a step up from the ground to the cab floor of only 17 inches (43 cm). The LR is a forward control cab-over-engine type. All three models are mechanically and visually similar. The LR is a direct evolution of the 1994 model LE and the upgraded 2007 TerraPro LE. Introduced in 2015 it remains in production in 2020. It is used in refuse service with front, side, and rear-loading refuse compactor bodies. The cab is very low-profile and has dual driving controls with a stand-up driving position on the right side. They are a forward control cab-over-engine type, where the driver sits in front of the axle. The Mack LR (Low Ride) is a series of heavy-duty ( Class 8) trucks built by Mack Trucks.

If only the actual collection could be quieter, too. That means running collection routes at night is more feasible in urban areas. Furthermore, getting rid of the internal combustion engine helps to make the vehicle much quieter. Maintenance should be less frequent for electric trucks, too, which increases uptime and operational efficiency. They follow prescribed routes, so predicting range is easy, and they return to the same location at the end of their cycles to charge. They drive slowly much of the time they're in use, and make frequent stops for collection. Garbage trucks seem particularly well suited to electrification. Our favorite touch, though, is the Mack bulldog ornament done up in copper, which is a feature specific to the It has regenerativeīraking, and can charge at up to 150 kW using an SAE charging plug. The truck uses a two-speed transmission to send that power to the rear axles. The motors provide a peak 496 (and 349 continuous) horsepower. The Mack electric garbage truck is powered by four NMC lithium-ionīatteries of an unspecified capacity and a pair of 130-kW AC electric motors. LR BEV Refuse Demonstration Model at WasteExpo 2019. Volvo subsidiary) has an even better solution. Thankfully, many waste management companies and municipalities have already moved toward cleaner garbage trucks running onĪlternative fuels, but they can still be polluting both in terms of Truck that - while it may take your trash and recycling from your curb - leaves behind a big plume of exhaust smoke. There's nothing quite like being woken up at the crack of dawn by a giant, slow moving
