Instruction Manual of Rear Loading and Unloading (Compression) Garbage Truck:

1. Overview

Chengli Special Vehicle Rear Loading and Unloading Garbage Truck is also called Compression Garbage Truck (hereinafter referred to as garbage truck) is a special vehicle used for the collection, transportation and unloading of bagged, barreled and bulk domestic garbage in cities and towns. The garbage is pushed into the truck compartment by the vehicle-mounted garbage propeller, also known as the negative pressure mechanism, so that the garbage is distributed at a higher density and more evenly in the truck compartment until it is full; the collection and transportation method of this garbage truck is currently widely used in the world. In the garbage collection and transportation mode, the functions of its special devices are powered by automobile engines and are realized manually or electronically through hydraulic mechanisms. The vehicle's box body, loader, also known as bucket body, and sewage tank are all made of high-quality carbon steel plates with fully sealed and welded structures, which have the advantages of high strength, light weight, and no secondary pollution.

This series of models can be equipped with an optional hydraulic trash can flip mechanism, which is suitable for 120-liter, 140-liter, 240-liter plastic trash cans and 350-liter metal trash cans.

The basic performance of the garbage truck is the same as that of the original chassis vehicle. Users please refer to the original chassis vehicle manual. This instruction manual only introduces the relevant operation, inspection and maintenance of the special modification parts. Before using the vehicle, we strongly urge you to read this manual thoroughly and become familiar with the operating procedures.

Our factory will further improve its products. Product improvements, performance enhancements, and structural improvements are subject to continuous improvement without prior notice, so some instructions may not apply to your specific vehicle, please understand.

IV. Brief description of structure

1. Carriage box

Chengli large compression garbage truck body uses No. 16 low alloy channel steel and 8mm, 5mm, 4mm , 16Mn steel plates are welded. The channel steel at the bottom of the carriage is not only the basic installation and connection component of the steel structure, but also the push plate support. Lightweight maximizes the effective space of the box and reduces the center of gravity of the structure.

Chengche’s standard compression garbage truck is welded with No. 12 low-alloy channel steel and 5mm, 4mm, and 16Mn steel plates. The box body is fixed to the car chassis through additional beams.

The bottom plate of the carriage is a fully sealed structure. Sewage corrodes and all accumulated water in the carriage is discharged into the sewage tank of the bucket body to avoid corrosion of the box and

car chassis, as well as to avoid leakage to the roadside during driving. Leaking and spilling sewage effectively prevents secondary pollution.

2. Bucket body

The bucket body is also called a garbage loader. The loader consists of a frame frame, a guide rail, a curved hopper, a scraper, a slide plate, a negative pressure plate and a light cover Composed of parts. Through the sequential actions of the scraper cylinder, skateboard cylinder and negative pressure plate, the function of cyclically pressing the materials in the hopper into the carriage is realized. Eight rollers are installed on both sides of the skateboard, which have low friction coefficient, high strength, and can swing slightly to ensure long-term use of the guide rail without wear.

The loader is also the sealing device at the rear of the carriage. It realizes the opening and closing actions through the lifting cylinder, sliding hinge and locking device.

There is a sewage tank at the bottom of the loader, and the accumulated water inside the carriage and the excess water in the hopper flow into the sewage tank. During unloading, all sewage in the sewage tank can be discharged automatically or manually.

3. Bucket turning mechanism

Based on user needs, a barrel turning mechanism, plate turning mechanism or bucket tipping mechanism can be installed. This mechanism adopts hydraulic double-acting double-cylinder turning, iron barrel or plastic barrel. The barrel is locked by the system during the flipping process, which is safe, stable, strong and structurally reasonable.

Note: When the vehicle is moving, the mechanism is turned up to facilitate normal driving.

4. Hydraulic system

The hydraulic cylinder action of this vehicle uses a circuit to control the air path, the air path valve controls the cylinder, the cylinder operates a hydraulic multi-way valve, and the hydraulic multi-way valve controls the cylinder action . The operation is simple and reliable, and it also has manual direct operation of the hydraulic multi-way valve and bidirectional control of a single hydraulic system.

The hydraulic system consists of a fuel tank and filter system, oil pump, multi-way reversing valve, one-way throttle valve, oil cylinder, oil pipe, etc. The power of the system comes from the engine, and the power is separated through the power take-off, which drives the gear pump to work.

The gear pump sucks the hydraulic oil in the hydraulic oil tank through the oil suction filter, and the multi-way valve (located behind the cab and at the front of the car) supplies oil. When the multi-way valve works, the negative pressure plate cylinder, skateboard cylinder, scraper cylinder, bucket lifting cylinder or push plate cylinder moves. When the hydraulic cylinder does not work, the hydraulic oil returns directly to the tank through the multi-way valve.

5. Maintenance

1. The use and maintenance of the chassis and engine parts of the vehicle shall be carried out in accordance with the provisions of the chassis vehicle instruction manual.

2. During the running-in stage of a new vehicle, the driving mileage is between 1,500-2,500km and the box is lifted (push plate) and unloaded within 900 times. The loading capacity is 70% of the rated load mass. The engine must not be used during unloading. Manganese blasts the throttle.

3. After the cylinder has been operated for 300 times, all working oil should be replaced. Unscrew the oil drain plug of the hydraulic oil tank, then inject new oil from the upper oil filling hole, then start the engine and test run each cylinder twice to confirm that it works reliably.

4. High-pressure oil pipes should be replaced regularly every two years. If cracks, damage, shoulder swelling, etc. are found during use, they should be replaced in time.

5. Check the oil leakage of the hydraulic system frequently, and repair and replace the oil seal in time.

6. General automotive lithium-based grease (GB5671-85) is used for lubrication. You can use a grease gun to drive it in from the grease nozzle until it is squeezed out from the gap.

7. Clean the entire vehicle, carriage box, and inner surface of the pressure filler after each day's work. Check the hydraulic oil inventory frequently, add lubricating oil to each moving part regularly, and apply lubricating oil to the surface of each guide rail.

8. Regularly check and adjust the working pressure of the gear oil pump; check the oil filter element, remove surface impurities or replace the filter element; regularly replace the hydraulic oil.

VI. Precautions

1. It is strictly prohibited to put construction waste into this series of garbage trucks to avoid damaging the machine parts.

2. If abnormal movement is found during the operation of the hydraulic system, the work should be stopped immediately, the cause should be analyzed, and the fault should be eliminated. Never force work.

3. Whether engaging or disengaging the power take-off, the clutch pedal must be depressed; when the power take-off and the multi-way reversing valve are in working condition, garbage must not enter the driving state.

4. The pressure regulating device of the hydraulic system is the pressure regulating bolt on the multi-way reversing valve. After the bolt has been adjusted and locked by pressure calibration, it must not be adjusted at will during use. Users are not allowed to adjust the oil pressure at will.

5. The one-way throttle valve on the top of the pressure packer is a device that controls the descending speed of the pressure packer. It must not be adjusted at will after it is set and locked.

6. The vehicle collection bucket should be closed until the collection bucket drops to the bottom, the lock tongue and the lock block are engaged, and the closing is completed.

7. Do not flush water into the hydraulic tank when washing the car. Check the hydraulic oil level frequently. If the hydraulic oil is insufficient, add it in time. All oil joints must not leak.

8. During maintenance, collisions should be prevented to avoid damage, deformation and scratches to parts. Pay attention to cleaning when assembling parts.

7. Judgment and treatment of hydraulic system faults

When the hydraulic mechanism is not working properly. You should first check whether the power take-off is correctly engaged, whether there is sufficient hydraulic oil in the tank, and whether the suction pipe ball valve is fully open.

1. The hydraulic mechanism has no action. Check according to the following steps.

a. Is there sufficient oil in the hydraulic tank? Hydraulic oil should be added when insufficient;

b. Observe whether the oil inlet pipe from the oil tank to the oil pump is deflated due to aging. If this occurs, the oil inlet pipe should be replaced.

c. Check whether the gear oil pump fails.

Install the pressure gauge, twist the pressure-regulating bolt, and observe whether the gauge reaches the specified value;

d. If the specified oil pressure still cannot be reached after the pressure-regulating bolt is fully screwed in, the gear oil pump has failed. Replace the gear oil pump;

e. If the gear oil pump works normally, the multi-way reversing valve spool is blocked. The valve core should be removed, cleaned of impurities, and reinstalled before use.

2. The hydraulic mechanism moves but is powerless

Check whether the gear oil pump fails and whether the system pressure reaches the specified value.

3. The hydraulic mechanism slows down

Check whether the gear oil pump fails and whether the suction oil filter and return oil filter core are clogged.
