Rear Loader Compressed Garbage Truck

Guide to Rear Loader Garbage Trucks

Introduction

Rear loader garbage trucks are a cornerstone in the waste management industry, known for their efficiency, versatility, and durability. This guide delves into the design, functionality, and benefits of rear loader garbage trucks, providing comprehensive insights into why they are widely used.

Design and Functionality

Loading Mechanism

A rear loader garbage truck is characterized by its loading mechanism located at the back of the vehicle. This design allows waste collectors to deposit trash directly into the rear of the truck. The rear loading mechanism typically includes a large hopper that receives the waste, which is then compacted by a hydraulic system before being stored in the main body of the truck.

Compaction Process

Once the waste is deposited into the hopper, a hydraulic mechanism compacts the trash, reducing its volume. This compaction process is crucial for maximizing the truck’s carrying capacity, allowing it to collect more waste before needing to be emptied. The compactor operates with significant force, ensuring that even bulky or dense materials are adequately compressed. After compaction, the waste is pushed further into the truck’s body, making room for more material in the hopper.

Advantages

High Capacity and Efficiency

Rear loader trucks boast high capacity and efficiency due to their compaction mechanism. This allows them to carry large volumes of waste, reducing the frequency of trips to disposal sites and saving time and fuel. The ability to compact waste also means that fewer trucks are needed to service a given area, which can lower operational costs for waste management companies.

Versatility

The rear loader design is compatible with various types of waste containers, making these trucks suitable for different environments. Whether servicing residential areas with smaller bins or commercial locations with larger containers, rear loader trucks can handle the task. This versatility allows waste management companies to deploy the same type of truck across different routes, simplifying fleet management and maintenance.

Ease of Operation

Rear loader garbage trucks are relatively simple to operate, particularly those with automated lifting arms. This ease of operation reduces the physical strain on sanitation workers, who would otherwise need to manually lift and dump heavy bins. The straightforward design also means that operators require less specialized training, which can reduce onboarding time for new employees.

Durability and Longevity

Built to handle heavy loads and operate in challenging environments, rear-loader garbage trucks are designed for durability. The robust construction and reliable hydraulic systems ensure that these trucks can withstand the rigors of daily use. With proper maintenance, a rear loader truck can remain in service for many years, providing a good return on investment for waste management companies.

Operational Requirements

Crew and Operation

In theory, a single worker can operate a rear loader garbage truck, but this would require the driver to repeatedly get in and out of the cab to pick up garbage cans and load them into the hopper. Therefore, rear loaders are typically operated by crews of two or three, with one driver and one or two loaders who hang onto the back of the truck while it travels from stop to stop.

Manual vs. Automated Loading

Unlike front and side loaders, rear loaders do not feature a loading arm that picks up cans and empties them into the hopper automatically. However, some models can be equipped with automated arms that can lift and empty containers into the truck. Human workers are often necessary to navigate obstacles or unforeseen complications that an automated arm cannot account for, which is common in residential waste management.

Suitability for Different Applications

Residential Curbside Collection

Rear loader trucks are highly suited for residential curbside trash collection. The low collection bin means workers don’t have to lift heavy loads over their heads, and the trucks can quickly and easily pick up trash from an entire residential neighborhood.

Commercial and Construction Sites

While rear loaders are not ideal for emptying large commercial dumpsters (a task better suited for front loaders), they can still be used in commercial districts and construction sites for clearing small to moderate-sized debris. Their versatility and compaction capabilities make them valuable in a variety of waste management scenarios.

Specifications and Maintenance

Key Specifications

Rear loader garbage trucks typically have specifications such as:
– A hopper capacity of three cubic yards or more
– Overall widths designed for enhanced stability
– Total body lengths that allow for greater efficiency
– High compaction rates (e.g., 1000 lbs. per cubic yard)
– Fast cycle times (e.g., 17–19-second cycle time)

Ease of Maintenance

Rear loading garbage trucks have fewer mechanical parts than other designs, making them simpler and easier to maintain. Features such as self-lubricating slide shoes and fewer lube points on the tailgate reduce maintenance requirements while boosting reliability.

Conclusion

Rear loader garbage trucks are a vital component of modern waste management due to their high capacity, efficiency, versatility, and durability. Their ability to handle a wide range of waste collection scenarios, from residential neighborhoods to commercial districts, makes them an indispensable asset for any waste management fleet. Understanding the design, functionality, and benefits of rear loader trucks can help waste management companies optimize their operations and ensure efficient and effective waste collection.

End Carriage

• The crane travelling system uses motor-reducer wheel driven systems with soft start motors for stable starting[2].

Electrical Equipment

• The electrical systems often use high-quality brands such as Siemens or Schneider, ensuring reliability and efficiency[2].

Safety Features

• Garbage grab cranes are equipped with safety features including overload protection, emergency brakes, and thermal protection for the main lifting motor. They also offer room control or remote control options to enhance operator safety[2].

Applications and Industries

Waste Disposal

• These cranes are widely used in city waste incineration plants to handle and process garbage efficiently[1][2][3].

Other Industries

• Besides waste disposal, garbage grab cranes can be used in various industries such as mines, ports, factories, workshops, and warehouses for handling and transporting incompact goods[2].

Conclusion

Garbage grab cranes are essential for the efficient and safe handling of garbage in waste management facilities. With their advanced control systems, robust construction, and multiple operational modes, these cranes ensure that garbage is fed, mixed, and weighed accurately, contributing to the smooth operation of incineration plants.
