In recent years, thanks to the growth of the domestic economy, the sales of semi-trailers in China have been on the rise. Especially in 2016, under the influence of the national policy to control excess, the sales of semi-trailers have been growing more rapidly.
However, after 2018, the dividend of the national policy to control excess was gradually released. Therefore, the sales volume of semi-trailers decreased in this year, but on the whole, the sales volume of domestic semi-trailers still showed an upward trend.
China’s semi-trailer transport vehicle, started in the 1950s, after decades of development, has begun to take shape. At present, the semi-trailer production enterprises in the country have developed to hundreds. SUNSKY TRAILER is one of them.
SUNSKY TRAILER was founded in 1998, mainly in the production and sales of flatbed trailers, fuel tanker trailer and bulk cement tank trailers of semi-trailer products. In 2020, SUNSKY TRAILER achieved good results, achieving annual sales of more than 5,000 units, including more than 1,100 units of semi-trailer Bulk Cement Tank Trailer sales.
Bulk cement tank semi-trailers are mainly used to transport dust materials with a diameter not greater than 0.1mm of dust materials, It is a kind of semi-trailer transporter that truck drivers often use. Although it is more common in life, its design and manufacturing process and the internal structure of the tank are not well known to everyone, today, we will talk about some things about the bulk cement tank trailer!
✅ With modern computer-aided design and force analysis, you can guarantee long service life of your products
The tank body of the SUNSKY bulk cement tank trailer adopts a three-dimensional design scheme. Three-dimensional design refers to the use of computers to represent the actual shape of the product in a three-dimensional model so that the three-dimensional model can contain more actual structural characteristics and can simulate the product, the real reflection of the actual product structure, and the processing and manufacturing process.
At the same time, the use of CAE force analysis, computer-aided analysis of the structure of the mechanical properties of the tank, and optimization of the structure of the performance so that the whole tank force is more reasonable so that the tank can have a longer service life.
✅ The external design of the tank should not only be beautiful, but also practical
After the design of the cement tank is completed, the actual manufacturing work is carried out. SUNSKY adopts laser cutting, which can improve the accuracy to 0.01mm. The mirror incision is formed once, which can reduce the cutting hot melt area as much as possible so that the steel plate element does not change, the rigidity is not lost, and the stress concentration phenomenon is not generated.
Then, the use of automatic CNC coil machine control, a cylinder molding, and an internal plate will not be damaged, and the forming quality is stable and reliable.

Then, the use of automatic CNC coil machine control, a cylinder molding, and an internal plate will not be damaged, and the forming quality is stable and reliable.
The next thing the rollers need to do is team up. The powder cement tank of SUNSKY adopts the frame-type formation process so that the left and right drums butt together. Such process equipment can ensure that the tank formation process will not be deformed and the appearance is beautiful.
And the size of the cylinder body and the design size are exactly the same, which can make the cylinder body have an ideal force layout so that the tank will not easily crack.
After the tank formation, it was the welding. Good welding process, not only can keep the welding seam of the tank beautiful, but also can ensure that the steel plate welding place will not appear concentrated stress, keep the tank steel plate has a good strength.
The SUNSKY powder cement tank adopts an automatic welding process, single side welding and double-side forming so that the tank has better strength.
After the shape of the tank is determined, it is also necessary to accurately locate the tank. Only accurate positioning can, as far as possible, avoid traction pin wear, suspension tire wear, trailer tail swaying, center of gravity deviation, and other problems.
This model tank adopts the base price level positioning platform, with the function of automatic height adjustment, according to the height difference of different brands of tractor saddle, to ensure that the trailer chassis and tractor saddle can be completely consistent.
✅ Tank unloading fast and less residual materials, internal design to be professional
Next, let’s look at the fluidized bed design structure inside the cement tank.
The Angle of the cylinder and side slide of the powder cement tank trailer is more than 2-3 degrees than other tanks in the industry, which can improve the fluidity of materials, reduce the residual amount of materials inside the tank and unload materials as soon as possible, among which the fastest unloading speed can reach 1.5 tons/min.
The powder tank discharge port also adopts the increased design, which can ensure that the material can be fully supplied when unloading and can achieve the fastest speed of unloading material, and the strengthening support of the discharge pipeline and the use of the triangle stability principle can ensure that in the process of unloading, there is no displacement of the pipeline and the best stability.
✅ Spray painting process is very important, not only to ensure the quality of tank trailer paint but also to pay attention to environmental protection
After the design of the external shape and internal structure is completed, it is necessary to spray paint the tank body. SUNSKY’s tanks are designed with a spray and powder process that allows the coating to last 5-8 years without fading. And the weatherability and corrosion resistance of the paint can be doubled compared with ordinary paint, the thickness of the coating reaches the H level, and it is not easy to be rubbed. Finally, the preliminary treatment does not contain phosphorus and heavy metal materials and is more environmentally friendly.
✅ Trailer pipeline design needs to pay attention to details; details decide the success or failure of the product
Finally, the layout and assembly of the pipeline outside the tank. In the pipeline, we should pay special attention to the details; the ball head adopts a stainless steel design, which is both beautiful and useful, and enhanced external support can make the tank bear better force. Laser weld, no stress concentration, so that the life of the tank is longer.
✅ Inspection is necessary. New trailers can only be put into the market if they meet the standards
When a new model is completed, it can only be considered a qualified product after passing all strict standards.
With the SUNSKY testing tower, complex road conditions, and vehicle inspection center test site, they can accurately test the residue discharging speed and the best location of tank size, the stability of vehicle and the vehicle’s brake and safety performance, only the performance of the vehicle has reached the national standard to enter the market for driving.
✅ Finally, service is the beginning of sales; even the very high-quality products need satisfactory service
An excellent product should not only have professional design methods and good manufacturing technology but also need to have satisfactory services, which can be regarded as a complete ecosystem.
SUNSKY TRAILER also has a perfect service system and service process for service and can achieve 24-hour service function. The service network has spread all over the country and can meet the needs of users at any time.
So far, this powder cement tank trailer has been introduced, now, we also have a relatively clear understanding of the internal structure and manufacturing process of the powder bulk cement tank trailer!
