![]() The two-speed transmission turns a drive shaft, which goes back to a rear axle to power the wheels. Those batteries send their juice to two electric motors, which connect to a transmission. The truck relies on four Lithium NMC (nickel manganese cobalt) batteries. “It’s a 50-yard dash, 800 1,000 times per day,” Barraclough adds, meaning that “you have a lot of opportunity for regenerative braking.” In that case, the dynamic motion of the truck slowing down helps charge the batteries. Plus, the start-and-stop nature of neighborhood garbage collection helps, too. That pattern lends itself well to charging, because “they’re home every night at the same location.” “Range is always a concern with any electric vehicle, but the nice thing about refuse vehicles is they’re generally running regular, predictable routes,” says Scott Barraclough, a product manager at Mack Trucks. Refuse is a good fit for an electric truckĪnyone who’s ever pondered a long drive in an electric vehicle has worried about charging it, but the rhythms of waste collection mean that’s less of an issue. Here’s what to know about how these super-heavy electric garbage trucks work, and why electrifying refuse vehicles in cities like New York isn’t a stinky idea. They could quietly cruise down streets in Manhattan, the Bronx, and other boroughs by 2023. ![]() The New York City Department of Sanitation acquired a Mack electric garbage truck in 2020 as a test vehicle, and now is planning on ordering seven more. Vehicles like the new Ford F-150 Lightning pickup truck represent a beefier type of electric conveyance, and one of the beefiest ones on the block are huge electric garbage trucks from Mack. But that’s not always the case, of course. Nowadays these vehicles are also called "dumper" in some mainland European languages.It’s easy to think about electric vehicles as just small, zippy rides like a Tesla or a Mustang Mach E. Dumpers are the most common cause of serious accidents involving construction plant. In the 1990s dumpers with swivel skips, which could be rotated to tip sideways, became popular, especially for working in narrow sites such as road works. Lifting skips are available for discharging above ground level. Some dumpers have FOPS (Falling Object Protection) as well. An A-frame known as a ROPS (Roll-Over Protection) frame, may be fitted over the seat to protect the driver if the dumper rolls over. They have multi-cylinder diesel engines, some turbocharged, electric start and hydraulics for tipping and steering and are usually four-wheel drive. Modern dumpers have payloads of up to 10 tonnes (11 short tons 9.8 long tons) and usually steer by articulating at the middle of the chassis (pivot steering). ![]() Originally advertised as the "dumping tractor", it soon became known as the Muir-Hill dumper. This allowed it to travel on tarmac roads or off road, which was of particular advantage on construction sites. Devised in 1927, and on sale by 1931, it gained a lot of versatility when in 1933 Dunlop introduced 'tractor-style' pneumatic low pressure tyres. One of the earliest British dumpers was the Muir-Hill, which was based on the Fordson tractor with 2 cubic yard bucket, driving on the front axle and steered by the back wheels. Continuous tracks allow the operator to carry heavier payload on slick, snowy, or muddy surfaces, and are popular in some countries. Dumpers with rubber tracks are used in special circumstances and provide a more even distribution of weight compared to tires. A towing eye is fitted for secondary use as a site tractor. The skip can tip to dump the load this is where the name "dumper" comes from. A dumper has a body which tilts or opens at the back for unloading and is usually an open 4-wheeled vehicle with the load skip in front of the driver. See de:Picco 1 (in German)Ī dumper or dumper truck ( British English) or dump truck ( North American English) is a truck designed for carrying bulk material, often on building sites. A Thwaites dumper in action A Neuson dumper A German-made Picco 1 dumper with one rear wheel in the midline. For other usage, see dumper (disambiguation). For articulated dump trucks, see articulated hauler. This article is about a smaller type of off-road vehicle.
