Working principle and structural characteristics of hanging garbage truck Hanging bin garbage truck is the oldest sanitation garbage vehicle, and is mainly used for garbage collection in iron bins inside city streets and residential districts. With the development of hydraulic systems, special-purpose vehicles and chassis technology, the reliability of the hydraulic system of the currently used hanging garbage truck has been greatly improved. The reliability of the entire vehicle has been improved, and the failure rate has been greatly reduced. In order to increase the service life of the trash can, the current use of glass steel trash can gradually replace the traditional iron trash can, reducing the impact of corrosion on the trash.

Hanging bucket garbage truck working principle and structure introduction 1. Working principle The work of the vehicle-specific mechanism adopts hydraulic drive.
Hydraulic system consists of fuel tank, oil pump, multi-way valve, hydraulic cylinder, oil filter and piping.
The power take-off takes power from the car engine and drives the oil pump to rotate. Manipulating the multi-way valve can separately control the lifting cylinder to complete the automatic loading work and control the lift cylinder to complete the unloading work.
The maximum working pressure of the hydraulic system is 16 MPa, which is defined by the safety valve on the multi-way valve. The pressure value of the safety valve has been set at the factory and should not be arbitrarily adjusted.
2. Structural Features The hanging garbage truck is selected from the standard truck chassis. The refitting part mainly includes: carriage assembly, automatic lifting charging device, hydraulic system, operating system and so on.
Car body assembly: All-metal sealed structure. On the right side of the front of the box, there is a feeding port and an automatic lifting charging device. There is an automatic door in the back of the car, which can be opened automatically when unloading.
Loading device: The automatic lifting charging device is installed on the right side of the front part of the carriage and consists of a bracket, a chain mechanism, a hook, and the like. Use this device to automatically lift the trash inside the bin into the compartment.
Self-discharging device: Double cylinder abdominal hydraulic lifting car body, complete automatic discharge.
Hydraulic system: Through this system, automatic lifting and automatic discharging can be realized.
Operating system: Through the system to achieve the conversion of various functions.
The work of the special mechanism for the hanging garbage truck is hydraulically driven.
Hydraulic system consists of fuel tank, oil pump, multi-way valve, hydraulic cylinder, oil filter and piping.
The power take-off device takes power from the car's engine and transmits the power to the oil pump through the drive shaft to drive the oil pump to rotate. Operation of multi-way reversing valve can separately control the lifting of the hydraulic cylinder to complete the self-loading work and control the lifting of the hydraulic cylinder to complete the discharge work.
When the multi-way reversing valve handle is not operated, the hydraulic oil discharged from the oil pump is returned to the tank via the multiple-way valve.
The maximum working pressure of the hydraulic system is 16 MPa, which is defined by the safety valve on the multi-way valve. Under normal conditions, when the system pressure exceeds 16 MPa, the hydraulic oil will flow back to the tank through the safety valve. At this time, it often indicates that the system is overloaded and the mechanism cannot work normally. The pressure value of the safety valve has been set at the factory and should not be arbitrarily adjusted.
