Concept
Garbage truck
Summary
A garbage truck is a truck specially designed to collect municipal solid waste and transport it to a solid waste treatment facility, such as a landfill, recycling center or transfer station. In Australia they are commonly called rubbish trucks, or garbage trucks, while in the U.K. dustbin lorry or bin lorry is commonly used. Other common names for this type of truck include trash truck in the United States, and refuse truck, dustcart, junk truck, bin wagon or bin van elsewhere. Technical names include waste collection vehicle and refuse collection vehicle (RCV). These trucks are a common sight in most urban areas.
Wagons and other means had been used for centuries to haul away solid waste. Among the first self-propelled garbage trucks were those ordered by Chiswick District Council from the Thornycroft Steam Wagon and Carriage Company in 1897 described as a steam motor tip-car, a new design of body specific for "the collection of dust and house refuse".
The 1920s saw the first open-topped trucks being used, but due to foul odors and waste falling from the back, covered vehicles soon became more common. These covered trucks were first introduced in more densely populated Europe and then in North America, but were soon used worldwide.
The main difficulty was that the waste collectors needed to lift the waste to shoulder height. The first technique developed in the late 1920s to solve this problem was to build round compartments with corkscrews that would lift the load and bring it away from the rear. A more efficient model was the development of the hopper in 1929. It used a cable system that could pull waste into the truck.
In 1937, George Dempster invented the Dempster-Dumpster system in which wheeled waste containers were mechanically tipped into the truck. His containers were known as Dumpsters, which led to the word dumpster entering the language.
In 1938, the Garwood Load Packer revolutionized the industry when including a compactor in the truck was implemented. The first compactor could double a truck's capacity.
