There are four basic models of garbage truck:

Scania front loader
Scania front loader
  • Front loaders generally service commercial and industrial sites using dumpsters (US term for large wheelie bins). They have large prongs on the front which are carefully aligned with arms on the dumpster. The dumpster is then lifted over the truck, until it is upside-down and the trash will then fall out into the receptacle.

  • Rear loaders commonly service residential areas. They have an opening at the rear that a trash collector can throw garbage bags or empty the contents of trash cans into. Often (particularly in Europe) they have a lifting mechanism to automatically empty wheeled bins (from both residential and commercial premises) without the operator having to lift the waste by hand. Another popular system for the rear loader is a rear load container specially built to fit a groove in the truck. The truck will have a wire / chain or strap system for lifting in the two "eyes" on the rear top. The waste will then slide into the tray of the truck. Normal sizes are 8 to 22 m³. The shown one is 12 m³.
    The rear loader is usually equipped with some type of compactor that will compress the garbage, and move it towards the front of the vehicle.
  • Side loaders are versions of either front or rear loaders that lift small trash containers or have openings on either side to deposit trash. Some side loaders are equipped with a mechanical remote-control arm that grasps a trash container such as a wheeled bin and empties it into the truck in the same manner as front loaders. This type of garbage truck requires only one arm-operator/driver but residents must position their wheelie bins carefully near the curb and at least two metres away from nearby objects.
  • Pneumatic collection, almost a 24 ton vacuum cleaner. On the top it has a crane with a tube and a mouthpiece that fits in a hole, usually hidden under a plate under the sidewalk. From here it will suck up garbage from an underground installation. The system usually allows the driver to "pick up" the garbage, even if the access is blocked by cars, snow or other barriers. [1]

There are also larger trucks that carry trash over long distances, usually modified dump trucks.

Garbage trucks empty their trash in landfills or combustion facilities. Most rear loaders lift the rear section so that the garbage will spill out. Front loaders more commonly have a moving wall that pushes the garbage out. Some larger landfills will have large contraptions that tip the entire truck, thus allowing the trucks to not have to carry their own method of emptying the garbage.


History

Wagons and other means had been used for centuries to haul away solid waste. Trucks were first used for this purpose soon after their invention. The 1920s first saw open topped dump trucks used for the purpose, but soon covered vehicles became used more often. The open tops tended to drop waste and had poor odours. These covered trucks were first introduced in more densely populated Europe than in North America, but were soon used everywhere. Sometimes referred to as the Jazz Age or primarily in North America and in Australia as the Roaring Twenties . In Europe it is sometimes refered to as the Golden Twenties. ...

The covered vehicles were still modified dump trucks, however. The main difficulty was that the garbage collectors needed to lift the trash to shoulder height. The first technique developed in the late 20s to solve this problem was to build round compartments with massive 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 solved this problem by developed a cable system that a could pull garbage into the truck. Look up hopper on Wiktionary, the free dictionary. ... 1929 (MCMXXIX) was a common year starting on Tuesday (link will take you to calendar). ...


In 1937 George Dempster invented the Dempster-Dumpster system in which wheeled garbage containers were mechanically tipped into the garbage truck. His containers were known as Dumpsters, which led to the word dumpster entering the language. 1937 (MCMXXXVII) was a common year starting on Friday (link will take you to calendar). ... George Roby Dempster (16 September 1887-18 September 1964) was an industrialist and inventor, and also served as mayor of Knoxville. ...

In British and Australian English, the term skip is more commonly used (although they are not perfect synonyms). ...


In 1938 the Garwood Load Packer revolutionized the industry when the notion of including a compactor in the truck was implemented. The first primitive compactor could double a truck's capacity. This was made possible by the availability of relatively cheap hydraulic presses. 1938 (MCMXXXVIII) was a common year starting on Saturday (link will take you to calendar). ... A compactor is a machine or mechanism used to reduce the size of waste material. ... The hydraulic press is a class of machine tool that was important in making possible the Industrial Revolution. ...


1955 saw the Dempster Dumpmaster the first front loader introduced. They do not become common until the 1970s, however. The 1970s also saw the introduction of smaller dumpsters, often known as wheelie bins which were also emptied mechanically. 1955 (MCMLV) was a common year starting on Saturday of the Gregorian calendar. ...

Since that time there has been little dramatic change. Compactor designs however, have been many and varied, one of the most popular being the traditional "sweep and slide" system where hydraulically-powered plates scoop out the garbage from a loading hopper and subsequently compact it against the material already loaded. The Heil Colectomatic used a combination of a lifting loading hopper and a sweeper blade to clear and compact garbage in anticipation of the next load.


So-called "continuous" compactors were popular in the 1960s and 1970s. The British Shark design (later Rotopress) used a huge rotating drum, analogous to a cement mixer, in conjunction with a serrated auger to grind down and compact the garbage. The Shelvoke & Drewry Revopak, used continuously rotating tines to crush large items with ease. High fuel consumption has seen a decline in the popularity of continuously compacting garbage trucks. The 1960s in its most obvious sense refers to the decade between 1960 and 1969, but the expression has taken on a wider meaning over the past twenty years. ... The 1970s in its most obvious sense refers to the decade between 1970 and 1979. ... The Rotopress is a European garbage truck manufactured by the German company Faun GmbH. Originally a French design, later interpreted by a British company known as Laird Engineering Ltd, the Rotopress is a continuously compacting garbage truck, meaning that the compacting process carries on uninterrupted, with no user intervention required...

There has long been the dream of the fully automated garbage truck that could do away with all but the driver. Some cities do have these systems (see Side Loader above), but they are generally unable to deal with unexpected situations.
