Dump semi trailer is a type of engineering vehicle. Its principle is that the engine drives the hydraulic mechanism to drive the lifting mechanism to complete tilting to achieve the purpose of unloading. After unloading, it is reset and the trailer lowers back to its regular horizontal position, which greatly saves unloading time and labor, shortens the transportation cycle, and improves production efficiency. It is widely used in mining, water conservancy construction, road construction and other fields.
When it comes to the lifting modes, dump semi trailers can be divided into rear dumping type and side dumping type. Let’s look at side dump semi trailer.
In fact, most dump trailers in the past were rear dumping type, but the rear dump semi trailer has high requirements for the height of the jacking rod. Generally, the height of the jacking rod is affected by the length of the carriage. The longer the length of the cargo compartment, the longer the length of the jacking rod is required. However, the ejector rod is designed to climb steadily. The thinner it gets to the top, so it is more unfavorable to the lateral stability of lifting.
In this case, the side dump semi trailer was invented. One of its biggest advantages is that the height requirement of the lifting jack is lower. As a matter of fact, it’s even less than half the height of the rear tipping jack. The top rods of the rollover semi-trailer are generally evenly distributed at the bottom of the cargo compartment in a line shape with a large lifting force and improved lateral stability. Especially for semi-trailers with long cargo compartments, side dumping is more suitable.
In addition, the design of side dump trailer is generally equipped with a shift rod, which can help reduce rollover to a certain extent, but it cannot be completely avoided. The trailer needs to be operated strictly and standardized procedure must be followed.
Of course, as long as there are advantages there will be disadvantages. The disadvantages of the side dump semi-trailer are also more obvious mainly because the requirements for the unloading site are higher. Meanwhile, the tires are easily buried during unloading and sometimes the goods are not unloaded cleanly. So, there are certain skills and tips when unloading a side dump semi trailer:
The unloading site should be level. This is the first thing trailer owners should pay attention to. Be sure to choose a place where the ground is flat to unload, especially if there are no slopes on the left and right sides. If the center of gravity of the dump trailer is shifted after it is raised, it is very easy to cause a rollover.
The ground for unloading should be firm. Dump trailers are generally heavy in weight. If the ground is soft, it is easy to cause the wheels to sink, the body to shake or the vehicle to roll over.
Convert the guardrail at the unloading part into a baffle. This is also a method provided by the car owner to prevent the tire from being buried. If the guardrail next to the tire is converted into a baffle, and attention is paid to the height from the ground, so that it is not easy to bury the tire when unloading.
Do not raise the ejector rod all the way at once. It is recommended that the owner pay more attention to the unloading process. Stop and observe the vehicle when the ejector rod is raised one section. If there is no deviation or buried tires, then raise to the next section.
Pay more attention to the unloading process. During the unloading process, the owner must observe the changes of the carriage from the rear window. If the tire sinks or the body tilts, the loading and unloading should be stopped immediately. It is best to arrange another person outside the car to assist with the observation.
Some owners say that when unloading the side dump semi-trailer, the tractor and the trailer can be kept at a certain angle, generally no more than 45°, to maintain the balance of the body.
It is worth noting that due to the lifting method of the side dump truck, the girder and the chassis are easily subjected to uneven forces during unloading. Therefore, requirements for the chassis, especially the axle are higher, which is not only a key component of the chassis load-bearing, but also related to the braking, driving and other performance of the vehicle. It must be 100% reliable. Vehicle Master has been mass-producing integrated axles for a very long time. We have accumulated over 15 years of experience and has the most innovative and advanced factories covering over 400,000 square meters. The strength, toughness and ductility of the axles can always be trusted. Fatigue resistance and other leading performance provide the maximum security for vehicel owners while improving the efficiency of vehicle operation.
