1, Self dumping operation steps
1. Basic preparation
- Start the vehicle and ignite it, press the clutch to shift into neutral.
- Turn on the power take-off switch (some models require pressing the neutral separation switch at the same time) to ensure that power is transmitted to the hydraulic pump.
2. Lift the carriage
- Slowly release the clutch and control the hydraulic system through the lever or switch to lift the carriage smoothly. Maintain a constant speed during operation and avoid sudden lifting or braking.
- For rear dump trucks, it is necessary to open the rear bucket locking device in advance to prevent accidents caused by the center of gravity shifting backwards.
3. Reset and Closing
- After unloading is completed, push the control lever to the descending position and slowly lower the top, and the carriage will be reset by its own weight.
- Turn off the power take-off, shift to neutral, and check if the hydraulic system has fully returned to its original position.
2, Key safety precautions
1. Environmental and ground conditions
- Choose a flat and solid ground for operation, avoiding slopes or soft ground that may cause the vehicle to tilt or roll over.
- Observe whether the tires sink during unloading, adjust the position or pause the operation if necessary.
2. Loading and operation specifications
- The goods should be evenly distributed to avoid overloading or center of gravity deviation.
- Do not suddenly switch to descent mode when lifting the carriage to prevent hydraulic impact from damaging the frame.
3. Personnel and equipment inspection
- Before operation, check the hydraulic pipelines, carriage structure, and braking system to ensure that there are no leaks or deformations.
- During operation, a dedicated person should observe the surrounding environment to ensure that no personnel or obstacles enter the hazardous area.
3, The differences between different types of dump trucks
- Tilting direction: Rear tilting is the most common, which pushes the carriage backwards through the piston rod; A few car models support tipping or bi-directional tipping dump trucks.
- Gearbox adaptation: Different gearboxes (such as 8th and 10th gears) have different gear shifting requirements, and heavy-duty gearboxes may not need to shift.
- Summary: The core of self dumping operation is hydraulic system control and stability management. Strictly following the steps and paying attention to safety details can significantly reduce risks. If you need further understanding of hydraulic principles or troubleshooting, you can search for hydraulic system maintenance for dump trucks.
