Truck Knowledge: Trucks Should Be Equipped with Suitable Carriage

When it comes to dump trucks, we all know that they play an indispensable role in the field of urban infrastructure and engineering mining. With the functional development of dump trucks, the carriages of dump trucks are becoming more and more diversified, and more practical to meet different needs of different users.
 
▎A brief analysis of the types of dump truck carriages
 
In our lives, dump trucks used for road transportation are the most common, but dump trucks used for mining transportation are very different from ordinary road transport trucks. When transporting some solid stones such as coal and ore, the dump trucks were more durable, and most of them used square carriages with higher thickness and larger volume. The new U-shaped carriages were not widely promoted until the later stage.
 
The cargo box that is biased towards road transportation has to take into account the issue of light weight. The traditional U-shaped carriage has gradually been polarized. Until now, only some trucks that focus on the transportation of urban muck and mine ores are in use. The reason why dump trucks are classified must be analyzed from their operating conditions.
 
(1) U-shaped carriage
 
First of all, let's start with the common urban muck trucks. They are equipped with U-shaped carriages, such as SINOTRUK HOWO-7. Urban muck trucks are a powerful driver for the rapid development of urban infrastructure. However, the environment of urban roads is also sensitive. The phenomenon of "dropping and leaking" of soil trucks on urban roads is serious, and the airtightness of ordinary carriages is not suitable for the transportation of muck.
 


The muck trucks has now replaced traditional dump trucks with new environmentally friendly vehicles. They have not only U-shaped carriages, but also automatic tarpaulins above, which greatly enhances the sealing of the cargo box and reduces the"drip and leakage” in urban roads. Because the design lines of the U-shaped carriage are relatively smooth, there is no leakage of reinforcing ribs on the main frame, which reduces the possibility of residual mud remaining in the cargo box.
 
In addition, the current U-shaped truck is much smaller than the ordinary square truck in volume. The reason why it is called a U-shaped truck is that the biggest essence is on the bottom of the truck. The bottom of the U-shaped truck is extremely smooth, which reduces the collision and impact of some large rocks and the bottom of the truck when the excavator is loaded. The unloading is cleaner and more durable, reducing the steps of excavator bucket cleaning.
 
(2) Square carriage
 
Compared with U-shaped carriages, square carriages are more popular in the field of road transportation. If there are no specific scenarios for transportation, most users may choose square carriages, which are boxy and have a larger volume. The main frame of the carriage can be customized according to the loading capacity, and the strength and clearance of the reinforcing ribs are extremely flexible in customization. For example, FAW dump truck are many drivers' choice.
 


However, the square carriages also have a disadvantage, that is, the fence and the bottom plate are not integrated, but are fixed by columns. If the usual loading capacity is large and the length of the cargo box is long, the middle of the fence is prone to expansion. This is also a major structural defect of the square carriage. However, many chauffeurs of heavy-duty trucks will add steel cables in the middle of the railings. The steel cables adjusted by the hoist can tightly restrain the railings on both sides, and are not subject to loading and unloading restrictions.
 
When it comes to versatility, the square carriage is also a winner, because the ordinary trucks with square carriages can transport not only sand, ore, coal, but also cement, stone, feed and other products, as long as the capacity of the carriages are enough. The expandability of the square carriage is much stronger than that of the U-shaped carriage. I think this is one of the reasons why road transport users prefer square carriages.
 
▎U-shaped carriage PK square carriage, who is better
 
According to the actual situation, we analyze the fields of infrastructure, mining transportation, and urban muck transportation, and analyze the advantages and disadvantages of U-shaped carriages and square carriages.
 
The bottom of the U-shaped carriage is in the shape of an inverted trapezoid, which is designed to make the gravity of the goods on both sides move closer to the middle. When loading some muck, coal, sand and gravel, it is not easy to stick when unloading.
 
At the same time, the U-shaped carriage design is also conducive to cleaning at the end of the transportation operation. If you encounter some clay, you no longer need to hold a hoe or a shovel to dig slowly, which is also very helpful for the cleaning of the cargo box. At the same time, the tail plate of the U-shaped cargo box is flat, and the sealing will be better, preventing the soil loaded from leaking on the road from the gap of the cargo box.
 
The appearance of the U-shaped carriage will also be more beautiful and fashionable. Many developed countries use U-shaped dump trucks. I believe that U-shaped trucks are also the future development trend of the industry. From the perspective of the structure of the U-shaped carriage and square carriage, some truck users think that they are both carriages, and the frame structure is the same, and only the shape of the bottom plate is different. In fact, it is wrong. From the perspective of the frame structure, there are more reinforced steel beams in the square carriage.
 
It can be seen from the picture that the bottom structural steel beams of the U-shaped truck are less than that of the square truck, mainly on both sides of the bottom of the cargo box. With this action, the side beams on both sides of the square truck can be saved. At the same time, the integrated railing of the U-shaped truck also limits the diversification of goods. On the contrary, the square truck can also improve the loading flexibility by modifying the column, which is also the reason why the bagged cement dump truck can set the side panels to be double-opened.
 


To sum up, when choosing a carriage from a professional field, the practicability and stability of the U-shaped carriage will be stronger than that of the square carriage, so it is dedicated to the special carriage. The versatility of the ordinary square carriage is also very friendly to many retail truck owners. Each of them has its own strengths to overcome the obstacles that the cargo box restricts the transportation of the types of goods.
 

 
▎Afterwords
 
The function of the dump truck is powerful, and the upgrade and evolution of the carriage is tantamount to enhancing its overall strength. Now the carriages of dump trucks all over the world have their own regional characteristics, which are customized in combination with local usage scenarios. The types of carriages have become more diversified, which can be classified according to the type of cargo box, dumping method, lift structure, etc. People no longer have to worry about choosing a carriage. It is also recommended that new dump truck drivers choose a suitable carriage according to their own transportation environment. More knowledge about trucks is at https://trucksglobal.com/faq/
