![]() ![]() Roll on/Roll offsĪ roll on/roll off garbage truck appears similar to a truck without a body. ![]() These trucks can collect 28 cubic yards (approximately 30,000 pounds) of compacted garbage per trip, which translates into nearly 1,500 homes. Needing only one worker per truck saves on labor by 50 percent and reduces the risk of injury. The machine could collect 300-gallon containers in 30-second cycles and the operator never had to leave the cab to operate the arm. ![]() The first ASL was used in the city of Scottsdale, Arizona in 1969. The arm is operated by the truck driver or another employee, and can be operated from either inside the truck, from the side of the truck, or by remote control. At the end of the arm is a grapple/pincher for picking up a garbage can in a similar fashion to how a human picks up a cup. The arm can swing out, extend, lower, grab, and the reverse of each of those functions. Automated side loaders (ASLs) come with one arm, which is far more capable than the arms of a front loader. Manual side loaders are similar to rear loaders except the waste is deposited into the truck via the side of the truck. There are two types of side loaders-manual and automatic. Most front loaders can lift containers weighing up to 8000 pounds and have capacities of up to 40 cubic yards. Since individual residences are unlikely to produce a bin of garbage each week, these trucks usually serve commercial clients. Now, bins stay on the properties of the customer and the customers fill the bins. Initially, workers would manually fill the bins, which were at ground level and had lower wall height. After they did, sales didn’t really kick off until the 1970’s. However, the company didn’t make their truck-the Dempster Dumpmaster-commercially available until 1955. The arms lower and the compactor in the truck’s hopper compacts the material. The arms rotate up, lifting the bin over the truck and dumping its contents into the hopper of the truck. Each arm slides through a slot on opposite sides of a garbage bin. The front loader garbage truck uses two “arms” or “forks”, which protrude from the front of the vehicle. Rear loader truck sizes range from 6 to 35 cubic yards with the largest ones being able to haul up to 18 tons (800-850 homes). Their versatility makes them a good choice for both residential and commercial garbage collection. Rear loader trucks continue to remain popular, because they offer high pressure compaction, good sealing, and offer easy, safe operation. Eventually, a tipping mechanism allowed the waste to be dumped out rather than manually removed. At which point, waste would have to be lifted above shoulder height to toss over the truck’s walls. They were loaded from the rear through the gate until the truck was too full to open the gate. Early versions of the rear loader had high side walls and a gate at the rear. Rear loader garbage trucks were the first type invented and today’s most popular. Today, this modern garbage truck has evolved into four different types. Now, solid waste collection companies could transport the same amount of waste with half as many trips. The invention proved to double the capacity of the trucks. More than forty years later in 1938, Garwood Industries, based out of Detroit, Michigan, revolutionized the industry by releasing a garbage truck equipped with a hydraulic press that compacted material. The goal of the purchase was to collect “dust and house refuse”. That’s when Chiswick District Council, a local government district in the county of Middlesex, England (1858-1927), purchased a steam motor tip-car from the Thorneycroft Steam Wagon and Carriage Company. Each one collects and transports solid waste to a treatment facility, such as a landfill, recycling center, or transfer station, depending on the waste and recycling programs available to the municipality.Īlthough wagons have been used for centuries to collect garbage from urban areas, none of them were self-propelled until 1897. There are four types of garbage trucks we see today. ![]()
