A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting. Also known as dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device and other components. The compartment of the dump truck is divided into two types: backward tipping and sideways tipping. The movement of the piston rod is controlled by the operating system. Tipper trucks are very common on the Dutch market.
Applications of dump trucks in the Netherlands
In the port construction of the Netherlands, dump trucks are often used. This is because dump trucks are often combined with excavators, loaders, belt conveyors and other construction machinery in civil engineering to form a loading, transporting, and unloading production line for earthwork, Loading and unloading of gravel and bulk materials.
Classification of dump trucks
The types of dump trucks vary depending on the occasion, agricultural dump trucks, mine dump trucks, garbage dump trucks, coal transport dump trucks, construction machinery dump trucks, and sludge dump trucks, among which mining and construction machinery dump trucks account for the proportion of the Dutch dump truck market bigger.
Advantages of dump trailer
Because the loading compartment can automatically tip over to unload at a certain angle, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, and reduces transportation costs. It is a commonly used special transportation vehicle. It is because of these irreplaceable advantages of dump trailer that the Netherlands has an increasing demand for imports of dump trailer.
Dump Trailer Maintenance
In order to prolong the service life of the dump trailer, reasonable and timely maintenance is very necessary
1. New dump trailer or overhauled trucks must be tested to ensure that the lifting process of the cabin is smooth and free of movement.
2. When using, all parts should be correctly selected according to the regulations, which greatly saves unloading time and labor, and the lifting mechanism strictly replaces the oil on schedule.
3. Ship according to the rated loading capacity, and overloading is strictly prohibited.
Dump trucks are so widely used in the Dutch market, operation standardization is very important. We have sorted out the following operating procedures, hoping to provide some reference for dealers who have just started dump truck business.
1. Do not suddenly push the lifting handle to the "down position" during full-load lifting.
If this operation error occurs, the carriage will rush down suddenly, which will bring a great impact to the frame, and even cause an accident. Therefore, the above-mentioned operations should be avoided as much as possible. If there are special circumstances, it must be operated carefully, and the landing speed should be slowed down as much as possible. It is necessary not to drop the carriage suddenly to the bottom.
2. It is not allowed to use the heavy lift truck-slam brake to unload the cargo.
Due to the large inertial force (generally 5~20 times of the rated lifting force), it is very easy to cause permanent deformation of the frame, open welding of the carriage and auxiliary frame, burn the oil pump or damage the sealing ring, damage the hydraulic cylinder and other damages. , the service life of the vehicle is reduced, and in severe cases, there will be a rollover accident. Therefore, it is generally forbidden to drive when the dump truck is lifted.
3. The dump truck must disengage the power take-off after unloading the cargo before driving.
If this operation error occurs, when the dump truck is driving, 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 oil temperature of the hydraulic oil rises rapidly, which can easily cause damage to the oil pump seal, and even cause the oil pump to "burn out"; what is 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 car to rise automatically during driving. accident.
4. The power take-off cannot be in the "on" position when driving.
If it is in the "on" state (the red light is on), the oil pump will continue to rotate, and the hydraulic system will have a power source, which will cause the car to automatically lift due to misoperation on the air control valve; Even if the control distribution valve is in the "down" position, the oil will enter the oil pump, which will cause the oil pump to burn out
