Garbage trucks or dustbins refers to trucks specially designed to collect municipal waste and transport waste collected to solid waste treatment facilities such as landfills. Other common names for this truck include the garbage trucks in the United States, and garbage trucks , garbage trucks , bins , bin wagon , garbage truck , bin lorry or bin van elsewhere. Technical names include garbage collection vehicles and refuse collection of vehicles . These trucks are a common sight in most urban areas.
Major US truck manufacturers include Mack and Truck Autocar. The main producers of the trucking agency (not the truck itself) include McNeilus, and Heil.

Histori
Carrots and other means have been used for centuries to transport solid waste. Among the first self-propelled trash trucks was ordered by the Chiswick District Council of the Thornycroft Steam Wagon and Carriage Company in 1897 depicted as a steam engine, a new design specifically for "dust collection and trash home".
The 1920s saw the first open trucks used, but because of the stench and sewage falling from behind, closed vehicles soon became more common. These closed trucks were first introduced in more populous Europe and later in North America, but soon used around the world.
The main difficulty is that the garbage collector is required to lift the garbage to the shoulder. The first technique developed in the late 20s to solve this problem is to build a round compartment with a large bottle opener that will lift the load and carry it from behind. A more efficient model was the development of a hopper in 1929. Using 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 moved into trucks. The container is known as Dumpsters, which causes the word dumpster to enter the language.
In 1938, Garwood Load Packer revolutionized the industry when ideas including tillers in trucks were implemented. The first primitive compactor could double the truck's capacity. This is made possible by the use of a hydraulic press that solidifies the contents of the truck on a regular basis.
1955 saw the first Dempster Dumpmaster front loader introduced, but they did not become common until the 1970s. The 1970s also saw the introduction of smaller trash bins, often known as wheelie rubbish which was also emptied mechanically. Since then there has been a slight dramatic change, although there have been improvements in the compacting mechanism to increase the load. In the mid-1970s Petersen Industries introduced the first grapple truck for city waste collection.
In 1997, Lee Rathbun introduced the Lightning Rear Steer System . The system includes an elevated rear cabin to drive trucks and operate loaders. This configuration allows the operator to follow a haul truck and load it continuously.

Type of garbage collection vehicle
Front loader
Front loaders generally serve commercial and industrial businesses using large waste containers with lids known as Dumpsters in the US. The truck is equipped with a powerful fork on the front that the driver carefully aligns with the arm in the waste container using a joystick or a set of levers. The waste container is then lifted on the truck. Upon arriving above, the container is reversed and garbage or recyclable material is emptied into the vehicle hopper. Once the waste is disposed of, it is compressed by a hydraulically powered moving wall that oscillates backwards and forwards to push the garbage to the rear of the vehicle. Most of the new packing trucks have a "hydraulic pack-on-the-go" that allows driver packages to load while driving, allowing faster route times. When the body is full, the compacting wall moves into the back of the body, removing it through the open tub. There is also a system called Curotto Can which is an attachment for a front loader that has an automatic arm that serves as an automatic side loader that allows the driver to throw carts.
Back loader
The back loader has a gap in the back so that the garbage collector can remove the garbage bag or empty the contents of the trash. Often in many areas they have a lifting mechanism for emptying large carts automatically without the operator having to lift the garbage by hand.
Another popular system for rear loaders is a special rear load container built to fit the grooves in the truck. The truck will have a chain or cable system to raise the container. The trash will slide into the truckcar.
Modern rear loaders typically condense the wastes using hydraulically activated mechanisms that use movable plates or shovels to extract waste out of the loading hopper and compress it to the moving wall. In most compactor designs, the plate has a pointed edge (thus giving the industry standard name of the packaging blade ) designed to apply point pressure to the waste to break large items in the hopper before being pulled into the trunk's main body.
The design of the compactor, however, has been numerous and varied, but the two most popular ones used today are the "sweep and slide" system (first pioneered on Leach 2R Packmaster), where blade packers rotate on moving trains that slide back and forth, and a "swing link" system (such as Dempster Routechief) where the blade is literally swinging on the "pendulum" -style mechanism. Heil Colectomatic uses a combination of lifting hopper and rotary sweeper to clean and condense the waste to anticipate the next load.
The so-called "continuous" compactor was popular in the 1960s and 1970s. The German Shark design (later Rotopress) uses a large rotating drum, analogue to a cement mixer, along with a jagged auger to grind down and compact junk. SEMAT-Rey from France pioneered a rotary scratching system (also used in British Shelvoke and Drewry Revopak) to destroy garbage and destroy large items. Other systems use large Archimedes screws to pull waste and mutilate in the body. Mixed security issues, and higher fuel consumption have decreased in the popularity of continuous solid waste trucks. Rotopress design remains popular because its niche is able to effectively handle green waste for composting.
The wall will move toward the front of the vehicle as pressure forces the hydraulic valve to open, or when the operator moves it with manual control.
The unique rear loading system involves rear loaders and front loading tractors (typically Caterpillar front loaders with Tink Claw) for wastewater collection (and in some cities, waste and recycling). The front loader takes the waste page set on the road, and then loaded onto the back of the rear loader. This system is used in several cities, including San Jose.
Side loader
Side loaders are loaded from the side, either manually, or with the help of a joystick-controlled robot arm with claws, used to automatically lift and tip the trash wheel into the truck's hopper.
Automatic side-loader
Trucks equipped with elevators are referred to as automatic side loaders, or ASLs. Similar to front-end loading, the waste is compressed by an oscillating packing plate at the front of the hopper loading that forces the waste through the hole into the main body and is therefore compacted into the back of the truck. An Automatic Sided Castler only requires one carrier, where a traditional rear load truck can require two or three people, and has the added advantage of reducing work injuries due to repeated heavy lifting. Due to these advantages, ASL has become more popular than traditional manual collections. Usually Automatic Side Loaders use standard wheeled trolleys that are compatible with automatic truck lifts.
Automatic semi-side loader
A semi-automatic side loader uses an automatic mechanism for lifting and disposing of manually aligned waste containers inside the truck's main body. The main difference from the semi-automatic side loader is that they require more than one person, to operate the truck, and to manually bring and align the containers to the loading of the hopper on the side of the truck.
As with the front loader, the compacting mechanism comprises a metal push plate in the collection hopper that oscillates backward and forward under hydraulic pressure, pushing the rejection through the gap, thus compressing it against the loaded material. In some ASLs there is also a "folding" crusher plate positioned above the opening in the hopper, which folds down to destroy large items within the range of metal pusher plates. Another compactor design is a "paddle packer" that uses a paddle that spins from side to side, forcing garbage into the truck's body.

Pneumatic collection
Pneumatic truck has a crane with pipe and mouthpiece that matches the hole, usually hidden under a plate under the road. From here it will suck up the garbage from the underground installation. This system usually allows the driver to "take" waste, even if access is blocked by car, snow or other obstacles.
Grapple Truck
Grapple trucks allow mass collection of waste. Most of the goods in the solid waste stream are too large or too heavy to be pulled by hand to a traditional garbage truck. These items (furniture, large appliances, branches, logs) are called large or "big" garbage. The preferred method of collecting these items is by grapple trucks. The Grapple truck has a hydraulic knuckleboom, tip with a clamshell bucket, and usually includes a dump body or trailer.
Roll-off
Roll-offs are characterized by rectangular footprints, utilizing wheels to facilitate rolling dustbins in place. These containers are designed to be transported by special roll-off trucks. They are relatively efficient for a lot of waste.
Bin tipper
A bin tipper , is a machine that mechanically lifts and reverses the trash for the purpose of emptying it. They often become larger engine components such as garbage trucks, or can be 'standalone' or mobile units. Bin tippers usually have steel, protective and seat frames, with a motor or crank-handle driving lifting mechanism, which may be hydraulic or chain operated. The bin is placed into the machine, then lifted and turned over to the target container, allowing its contents to be emptied by gravity.
Sideboard tip was installed on a garbage truck as early as 1929, by Heil company in America. In the 1950s Dempster Dumpmaster popularized front-end loader variants, with the truck's upturned truck truck. Both types of integrated tipper bin are now common in urban trash collection trucks. Tipping bin standalone was developed later, with the release of a machine called Simpro Ezi-Dump in 1990.
The use of tippers bin and other lifting aids has been stimulated in recent years by research connecting heavy manual removal with musculoskeletal disorders; some government organizations, schools and companies now prohibit emptying waste by hand. Health and safety issues have also encouraged the use of tippers bin in manufacturing, food processing and construction industries.
