Dump truck, also known as tipping truck, mining truck, etc. The dump trailer carriage adopts rear-dump and side -dump self-unloading methods, which improves the efficiency of the bulk cargo transport by the loader.is a vehicle that unloads goods by hydraulic or mechanical lifting. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device.
In general, which models of dump trucks have more commercial use? Tipping trucks are mainly used in civil engineering, often combined with excavators, belt conveyors and other construction machinery to form a loading, transportation, and unloading production line for earthwork, sand, and bulk materials. The loading and unloading transportation work; of course there are many other tractor tipper trailer such as mine dump trucks used to transport coal mines, sand and gravel; sanitation green dump trucks used to transport garbage and so on. It brings great convenience to people's production and life.

Although dump trailer owners drive carefully, traffic accidents still occur. In traffic accidents, the most frightening thing is dump trucks. Due to the high quality, difficult braking, and large blind spots, the loss caused by accidents is unimaginable. However, as long as the safety performance of the dump truck is in place, the safety is still guaranteed.
Brake configuration
The end dump trailer has a heavy weight and long braking distance, especially after loading the cargo. However, in the current dump trucks, there is no upgrade of the vehicle in this configuration, which makes the safety performance unchanged. The brake pads of the dump truck have been greatly upgraded in this respect, and they are also equipped with an ABS anti-lock brake system, which makes the braking distance of the vehicle shorter and the safety more guaranteed.
Tire pressure monitoring configuration
As the only part of the tipper semi trailer that contacts the ground, the tire pressure actually affects the safety of the vehicle to a large extent, but the dump truck transportation generally has a long working cycle, and the driver will be very tired after working for a long time, so I will not pay attention to these details. The change of vehicle tire pressure will affect the fuel economy and safety of the vehicle. If the tire pressure is not kept within the normal range in time, it may cause an increase in fuel consumption or a tire burst.
The driver can keep track of the tire pressure of the vehicle at any time, so as to adjust in time, so as to avoid the loss caused by the tire pressure being too high or too low, and driving is safer.
Anti-rollover configuration
Dump truck rollover is a common traffic accident. The body of the triple axle dump trailer is not easy to control and it is difficult to turn. There are not many rollover accidents. Moreover, in rainy or snowy days, the driving conditions are complicated and problems are more likely to occur.
The front and rear axles of the car chassis are now equipped with stabilizer bars to prevent rollover, which greatly improves safety performance, and there is also a lateral dual hydraulic shock absorber under the cab, which also has the prevention Roll function.

Matters needing attention during driving
1. Do not suddenly push the lifting handle to the "down position" in the middle of full load lifting.
If this operation error occurs, the car suddenly descends, which will bring a lot of impact to the frame and even an accident. Therefore, the above operations should be avoided as much as possible. If there are special circumstances, you must operate carefully. Slow down the landing speed as much as possible. You must avoid suddenly dropping the carriage to the end.
2. Do not use the emergency brake to unload.
Due to the great inertial force of driving forward suddenly, it is easy to cause permanent deformation of the frame, welding of the carriage and the subframe, burning oil pump or damage to the sealing ring, damage to the hydraulic cylinder, etc. There was a rollover accident. Therefore, it is generally prohibited for dump trucks to drive while lifting.
3. After the tipping truck unloads the goods, the power take-off must be disengaged to make the dump truck trailer feasible.
If this operation error occurs, when the semi tipper trailer is running, because the power take-off is in the "engaged" position, the lift oil pump will run at high speed for a long time without load in the "small cycle" state. As a result, the temperature of the hydraulic oil rises quickly, easily causing damage to the oil seal of the oil pump, and even the phenomenon of "burning" of the oil pump; more serious is that the operation of the oil pump means that the hydraulic system has a power source, and it is easy for the cabin to rise automatically during driving Accident.
4. The power take-off must not be in the "connected" position while driving.
