The used Howo dump truck can be divided into two types: side dump and rear dump. Each used Howo dump truck has a different operation process. The following describes the two types of used Howo dump trucks in detail and explains their main operation steps.
Whether the used Howo dump truck is a side dump or a rear dump, the driving operation is basically the same:
Select gear: Select the proper gear based on the configuration of the used Howo dump truck. If it is a manual transmission, it needs to be operated through the clutch and shift lever; If it is an automatic transmission, only through the throttle and brake control.
Start: manual transmission models need to slowly release the clutch and gently press the accelerator to make a smooth start for the used Howo dump truck; The automatic, with a light step on the accelerator, used Howo dump truck can run smoothly.
Control the speed during driving: During the driving process, you should pay attention to observe the road conditions ahead, and use the brake and throttle rationally to control the speed. Avoid sharp braking or acceleration. Especially in regions like Africa, countries such as Uganda, Rwanda, Tanzania, and Kenya often have uneven roads, requiring drivers to control their speed while driving.
Howo dump truck operation for side tipping:
(1) Parking: Drive the used Howo dump truck to the unloading site. Apply the brake and pull the handbrake to ensure the used Howo dump truck stops firmly.
(2) Start lifting operation:
First step on the clutch of the used Howo dump truck and turn on the force extractor.
Then slowly release the clutch and gently press the accelerator to transfer the engine power to the hydraulic system.
(3) Unloading: When the used Howo dump truck is running smoothly, press the flip switch of the side dump truck, and the side dump truck will automatically open and turn over to unload the materials.
(4) Complete unloading: After unloading is complete, the side tipper of the used Howo dump truck will automatically close to ensure that the tipper will return to its original position.
(5) Reset operation: If the dump is not completely closed or reset, you can press the dump switch again to ensure that the side dump of the used Howo dump truck is completely reset.

Howo dump truck operation for rear dump:
(1) Stop: Stop the car and pull the handbrake to ensure the used Howo dump truck stops.
(2) Start the lifting operation:
Press on the clutch of the used Howo dump truck and open the hydraulic valve.
Open the power take-off, then slowly release the clutch, and gradually fill the gas, so that the hydraulic system starts and the cargo compartment begins to rise.
(3) Unloading: When the cargo compartment of the used Howo dump truck rises to an appropriate height, the material will begin to dump.
(4) Complete unloading: After the materials are unloaded, step on the clutch, close the power take-off, and then close the hydraulic valve. The compartment of the used Howo dump truck will then gradually descend and reset.
(1) Parking location: Drive the used Howo dump truck to a suitable parking location to ensure that there are no obstacles affecting parking.
(2) Parking operation: Depress the brake and pull up the handbrake to ensure that the used Howo dump truck is parked firmly.
(3) Turn off the engine: Turn off the engine and pull out the key to complete the parking operation.
The used Howo dump truck operates differently for different types of gearboxes:
Sinotruk gearbox: Just depress the clutch and turn on the power take-off switch, then put the handle into the lifted position, and finally release the clutch to start the lifting operation.
Fast gearbox: You need to hang the gearbox to the low gear area, and then perform the rest of the operations after shifting the low gear. This is similar to the operation of a Sinotruk gearbox.
When operating the used Howo dump truck, in order to ensure safety, extend the service life of the vehicle, and avoid breakdowns or accidents, some operating specifications and precautions need to be strictly followed. Here are some key considerations for using the used Howo dump truck:
In any case, traffic rules and safe operating procedures must be observed when operating the used Howo dump truck. Especially on busy construction sites or roads, stay alert to ensure that there are no people or obstacles around and avoid unnecessary collisions or accidents.
Always wear necessary safety equipment such as hard helmets and reflective vests etc. to ensure the safety of the operator and those around you.
Periodically inspect the various critical parts of the used Howo dump truck. Especially the hydraulics, gearbox and engine etc of used Howo dump truck make sure they are in good working order.
Before each use of the used Howo dump truck, check the hydraulic oil level and quality to verify that there is no leak in the hydraulic system. The transmission oil and engine oil should also be kept in the normal range.
Check the tires, braking system, lights, mirrors, and more to ensure the stability and visibility of the used Howo dump truck during the drive.
When lifting the cargo compartment, make sure there are no people or obstacles around. Please always keep an eye on the surroundings during operation to ensure that no one is close to the lifting and lowering part of the used Howo dump truck to avoid accidental injuries.
Avoid improper handling during lifting. If not operated properly, the sudden drop of the cargo compartment may cause a serious impact on the frame and even cause an accident.
During the unloading process, do not overload or speed operation. Overloading not only accelerates the wear and tear of components such as the hydraulic system, axles, chassis, and more, but can also lead to damage to the hydraulic pump or a decrease in the stability of the used Howo dump truck.
Unloading is carried out in strict accordance with the rated carrying capacity of the used Howo dump truck to avoid excessive use of the hydraulic system and ensure the long-term stable operation of the used Howo dump truck.
Risk of operation error: When fully loaded, if the lifting handle is suddenly pushed to the lowered position, the carriage will suddenly drop. This can put a huge impact on the frame of the used Howo dump truck, and even an accident can occur. In order to avoid this situation, operational errors should be avoided. If necessary, operate slowly to ensure the smooth descent of the carriage. Avoid suddenly putting the carriage to the bottom.
Damage caused by inertial force: During the lifting process, if you suddenly accelerate or brake suddenly, the used Howo dump truck will generate a large inertial force (generally 5 to 20 times the rated lift force). This inertia can cause permanent distortion to the frame of the used Howo dump truck. In severe cases, it may lead to open welding of the carriage or attached frame, damage to the oil pump, sealing ring, and even damage to the hydraulic cylinder. This operation for a long time will greatly reduce the service life of the used Howo dump truck, and may even cause a rollover accident in severe cases.
Do not perform lifting operations while driving: used Howo dump truck should not perform lifting operations during driving to avoid unstable conditions leading to accidents.
Avoid damage to the hydraulic system: After unloading, if you forget to disengage the power take-off, the oil pump will run at high speed and no load in a "small cycle" state. This will cause the hydraulic oil temperature to rise sharply, increasing the risk of oil seal damage, and in severe cases, it may burn out the oil pump. Moreover, the oil pump is still running, which may cause the hydraulic system of the used Howo dump truck to have a power source, causing the carriage to automatically rise, further increasing safety hazards.
Consequences of operation errors: If the hydraulic system of the used Howo dump truck continues to work while driving, it may cause the carriage to rise unexpectedly, causing danger.
Prevent automatic lifting: If the power take-off is in the "ON" state (red light is on), the oil pump will continue to turn and the hydraulic system will keep supplying power. Even if the pneumatic control distribution valve is in the "down" position, there is still oil flow into the oil pump, which may cause the compartment of the used Howo dump truck to lift automatically, causing the oil pump to overheat or even burn out.
Ensure that the power take-off is closed: When driving, ensure that the power take-off is in a closed state to avoid unexpected operation causing the hydraulic system to lose control and ensure the safe driving of the used Howo dump truck.
Overall, the operation of the used Howo dump truck, while relatively simple, can lead to vehicle failure or safety incidents if details and safety specifications are ignored. Check and maintain the used Howo dump truck regularly by following the above operational considerations. This not only improves work efficiency, but also greatly extends the service life of the used Howo dump truck and ensures safety during operation.
