Common troubleshooting and maintenance of compactor garbage trucks

How to troubleshoot when the Isuzu compactor trash truck fails? Mastering the necessary maintenance skills will be of great help in daily use and avoid affecting the efficiency of equipment use. Today, we specially analyze the causes and countermeasures of common faults of Isuzu garbage compactor trash truck one by one, so that everyone can deal with these problems calmly.

A. No action in the compator cycle:

1. Abnormal proximity switch sensing, adjust the proximity switch sensing distance or replace it;

2. The button of the rear control box fails, check whether the wire connector is loose, if loose, tighten it, check whether the switch is damaged, if damaged, replace it;

3. The hydraulic system pressure is insufficient or no pressure, check whether the overflow valve, gear oil pump, and power take-off are working properly;

4. The wiring harness connector is loose, replace the connector;

5. The electromagnetic valve is working abnormally, check the circuit of the electromagnetic valve, whether the gas path is normal, and whether the valve is damaged;

B. The lifting action of the stuffing machine does not respond: 

1. The gear pump leaks, replace the gear pump;

2. The pneumatic piston of the power take-off is stuck or the connection between the output shaft of the power take-off and the oil pump is damaged, remove the stuck object or replace it;

3. The stuffing machine is too heavy, the garbage is not pressed into the garbage bin, and the sewage tank is overflowing. Press the garbage into the garbage bin and discharge the sewage;

4. The lifting cylinder leaks, replace the lifting cylinder;

5. The proximity switch on the top of the car is abnormal, replace the proximity switch;

6. The lock hook and the stuffing machine hook are too tight, adjust the lock hook U-bolt;

C. The lowering action of the stuffing machine does not respond:

1. Prevent the stuffing machine from The lowering switch of the filler is in the open position and is turned to the normal working position;

2. The valve core of the solenoid valve group on the lifting cylinder of the filler is stuck, so it should be removed and cleaned;

3. The solenoid valve coil on the lifting cylinder of the filler is damaged or cannot be powered, so replace the solenoid valve and check the circuit;

4. The lower limit induction switch of the filler is damaged, so replace the induction switch;

D. The lifting mechanism cannot be lifted in place:

1. The pins and copper sleeves at the joints are worn, so replace the pins and copper sleeves;

2. The lifting cylinder leaks, so replace the cylinder;

3. The hydraulic system pressure is insufficient, so readjust the hydraulic pressure Overflow pressure is within the standard range;

E. Automatic throttle system does not work:

1. Abnormal contact of clutch pedal contact switch, adjust or replace contact switch;

2. Abnormal contact of brake pedal contact switch, adjust or replace contact switch;

3. Abnormal throttle relay in the electric control box, check or replace relay;

4. Abnormal CAN bus controller or PLC in the electric control box, check or replace;

5. Abnormal operation of chassis automatic cruise, check whether the cruise switch is in the OFF state or check whether the switch is normal;

For ISUZU garbage compactor loader, fault handling ability is important, but preventive maintenance is the key to determine whether ISUZU garbage compator truck can be used for a long time. Regular comprehensive system inspection is the key to avoid failure. It is recommended to conduct a comprehensive inspection at least once a month, focusing on the hydraulic system, electrical system and mechanical connection parts.

1. Hydraulic system maintenance, regular replacement of hydraulic oil, check whether there is leakage in the oil circuit, and ensure that the oil is clean and the oil level is appropriate. It is recommended to use high-quality hydraulic oil and strictly follow the replacement cycle recommended by ceectrucks.

2. For precision parts such as proximity switches and solenoid valves, keep them clean to avoid dust and impurities.

3. For the electrical system, focus on checking whether the wiring harness connection is tight and whether there are signs of corrosion. Use waterproof connectors, clean the terminals regularly, and apply anti-corrosion lubricants. Keep the battery connection clean and remove the oxide layer in time.

4. For the maintenance of mechanical parts, lubricate each joint and moving parts regularly, and check the wear of the pins and copper sleeves. It is recommended to use high-quality grease and strictly implement the lubrication plan.

5. Driving operation is also an important part of preventing failures. Avoid overload, operate each system smoothly, and do not suddenly apply excessive pressure. Garbage should be evenly distributed when loading to prevent local overload.
