How does the 6-ton Hezhong lightweight side-tipping dump semi-trailer with a waterproof edge 1.49 meters above the ground achieve both lightness and safety

2025-09-12


With the strengthening of the traffic management department's governance of overloading transportation, under the weight-based charging system, the lightweighting of trailers has become a trend. At the same time, with the improvement of safety awareness, how to make side-tipping dump semi-trailers both light and safe has always been a difficult problem in the trailer industry.

Safety and weight reduction are not in conflict, but many people overlook the primary and secondary aspects. The particularity of the trailer industry determines that safety comes first. Hozon has been exploring how to strike a balance between weight reduction and safety for side-tipping dump semi-trailers and has finally found the answer. The chairman of Hezhong Trailer disclosed.

The answer mentioned by Hezhong refers to the Hezhong lightweight side-tipping dump semi-trailer (hereinafter referred to as Hezhong Lightweight Side-tipping). How does this semi-trailer achieve balance and be both light and safe?

With a self-weight of 6 tons, it is reasonably lightweight

It is easy to blindly reduce the weight of a side-tipping dump semi-trailer, but a reduction that sacrifices safety will never be done by Hezhong. The chairman of Hezhong Trailer disclosed that side-tipping dump semi-trailers usually transport hard and heavy goods such as coal and sand and gravel. Given the special nature of the goods, high requirements are placed on the carrying capacity. During the research and development of Hezhong's lightweight side-tipping trucks, weight reduction must be carried out with extreme caution.

The Hezhong lightweight rollover adopts a 300-kilogram class rollover special axle, and the steel rims are made of super lightweight 28kg low-carbon steel rims. Compared with ordinary steel rims, the self-weight is reduced by 150kg. The entire vehicle is made of high-strength steel materials of sufficient thickness, such as Baosteel and Taiyuan Iron & Steel, making it lighter in weight and stronger in strength.

The height of the waterproof edge from the ground is a highlight of the lightweight rollover feature of Hezhong. The waterproof rim is 1.49 meters above the ground, effectively reducing the vehicle's weight, lowering the center of gravity and height of the semi-trailer, increasing the cargo space, and at the same time, under the height limit driving system, saving fuel costs.


Ultra-high load-bearing capacity, safe and worry-free


For a long time, side-tipping dump semi-trailers have been the preferred choice of customers due to their large cargo capacity, good unloading stability and high safety factor. However, side-tipping dump semi-trailers also have their pain points, with frequent occurrences of frame cracking, weld opening of brackets, and tire wear.

During the research and development period of the lightweight side-tipping vehicle of Hezhong, we have always adhered to the corporate positioning of "Hezhong trailers, professional and more powerful", paying attention to every detail and being meticulous about every process. The chairman of Hezhong Trailer disclosed.

The goods transported by side-tipping dump semi-trailers are heavy, so higher requirements are placed on the vehicle chassis, especially the axles and tires. The axle is not only a key load-bearing part of the chassis but also related to the braking and driving performance of the vehicle. Therefore, the selection of axles and tires for side-tipping dump semi-trailers is of Paramount importance.

According to the loading habits of the side-tipping dump semi-trailer, Hezhong Lightweight side-tipping selects 300-kilogram class side-tipping dedicated axles. This axle has innovatively developed a thickening process for the axle head at a specific position, achieving the dispersion of force on the axle head and enhancing the durability of the axle. The tires selected are special anti-load, wear-resistant and side-rolling tires, which are pressure-bearing, durable and have a long service life.

The 5+1 oil cylinder of Hezhong Lightweight side-tipping adopts a "hybrid cylinder" design. Different cylinder diameter schemes are formulated for different cylinder spacings, which greatly improves the unloading efficiency and avoids the problem of uneven cylinder load capacity caused by different cylinder spacings, resulting in asynchronous lifting and thus affecting the unloading efficiency. The Hezhong lightweight rollover adopts a lifetime maintenance-free balance beam. The base plate adopts a 1.8 high-strength base plate.

In response to the cracking problem of the flip beam, Hezhong innovatively designed an integrated through-type flip beam. The steel is integrally formed, featuring high integrity, strong load-bearing capacity and greater durability. It can effectively prevent problems such as weld deformation caused by uneven force distribution. The integrated through-type flipping bracket reinforcement design fundamentally eliminates the problem of bracket welding opening.

The sideboard is dual-purpose and highly maneuverable

In modern logistics transportation, goods show a diversified trend in types, and unstable sources of goods and flexible routes have also become the norm. The more types of goods can be transported and the wider the routes can be covered, the higher the economic benefits for customers will naturally be.

However, due to the particularity of the loading and unloading method, the side-tipping dump semi-trailer can transport a single type of goods, mainly some bulk cargo. In response to this issue, Hozon has developed this dual-purpose side-tipping dump semi-trailer that can both dump short and load goods. Innovatively adopt the box opening method of lifting from top to bottom. When used for side-flipping, the sideboard is lifted apart during the unloading process. When used for cargo vehicles, the lower part of the sideboard is marked as a standard compartment.



The dual-purpose design of the Hezhong lightweight side-tipping guardrail expands the coverage of supply sources, effectively enhances the mobility and flexibility of the trailer, and undoubtedly increases the economic benefits of customers.
