Many people have heard of or seen Hezhong trailers on the road. Thanks to their excellent workmanship and lightweight and durable quality, they are loved by users. Last year, they achieved an impressive sales performance of 20,000 units.

Recently, Hezhong Trailer launched 17 standard container skeleton trailers. These trailers have undergone significant upgrades and optimizations compared to previous models, resulting in lighter weight and better performance. Hezhong's 40-foot container skeleton trailer is sure to have some unique design features. Let's take a look at some of its highlights.

This trailer weighs only 5.3 tons, more than 300 kilograms lighter than similar products. It features a straight beam structure, is equipped with 12 locks, and can transport one 40-foot container or two 20-foot containers. Besides its weight advantage, this container skeleton trailer has many highlights. The quality of a trailer depends heavily on the details of its workmanship, mainly reflected in its design, welding, and wiring layout. Therefore, we will focus on introducing this trailer in terms of manufacturing process and lightweight design.

● First, let's look at the details: The welding and painting are quite good.

The trailer uses a yellow paint job, which is common on skeleton trailers and is very eye-catching. Although the matte paint is not very glossy, it is applied evenly and the overall quality of the car is good.

Beneath the yellow topcoat is an electrophoretic primer. This trailer uses an electrophoretic process, which involves electrophoresis after shot blasting to remove rust. This electrophoresis leaves a layer of paint that significantly enhances the trailer's corrosion resistance. It is claimed that Hezhong is the first manufacturer in China to perform overall electrophoresis on trailer beams.

Welding Process Comparison:

The quality of a trailer is heavily reliant on its welding process. The smooth and uniform welding of the main beams in this trailer indicates excellent welding quality. This skeleton trailer utilizes robotic welding, making Hezhong the first trailer manufacturer to adopt this method. Compared to manual welding, it eliminates uneven weld seams and maximizes both strength and aesthetics. Furthermore, robotic welding significantly reduces the overall welding time, improving production efficiency.

Let's take a look at the more concealed areas inside the main frame. The welds are smooth and even, indicating that the welding process of this skeleton trailer is consistent throughout, and the overall welding of the trailer is excellent.

● Unique Design Ensures Strength and Reduces Weight

We found many lightweight designs in this skeleton trailer. Although each individual design may not reduce weight by much, the cumulative effect is significant. According to the manufacturer, this trailer weighs only 5.3 tons, while similar trailers from other manufacturers generally weigh over 5.6 tons, giving it a clear advantage in weight. Replacing the wheels with aluminum alloy wheels would further reduce the weight by over 200 kilograms.

What specific proprietary lightweight designs does Hezhong trailer feature? Let's continue reading.

The trailer's main beam web plate features a multi-ribbed design to increase its strength. Unlike other manufacturers, this trailer's rib design is more rational, ensuring beam strength while reducing weight. Additionally, notches are present at both ends of the ribs to release stress under load. Due to the significant load-bearing capacity at the outriggers, these areas also feature ribs to enhance the strength of the main beam at the suspension points.

Crossbeam support comparison:

The crossbeam of this trailer from Hezhong is a variable cross section, and the support is made of high-strength steel plate stamping. The round holes on it are to reduce the weight. Compared with the channel steel crossbeams and channel steel supports used by other manufacturers, it can reduce some weight while ensuring lightness.

Comparison of Suspension Beam Reinforcement

At the axle suspension position of the trailer beam, this trailer uses a reinforced lower flange and web plate design, which reduces the self-weight of the trailer beam while ensuring strength. Currently, most skeleton trailers use an additional web plate to increase beam strength; this design can be considered another highlight of Hezhong's skeleton trailer.

We found that the trailer crossbeam at the outriggers has a flanged design. The advantage of this design is that it can meet the strength requirements without adding an extra crossbeam.

To achieve overall weight reduction, this frame trailer utilizes numerous aluminum components to decrease its tare weight.

1. Aluminum alloy guardrails are used at both ends of the trailer, reducing weight while enhancing aesthetics and preventing corrosion.

2. An aluminum alloy toolbox is located on the right side for convenient carrying of tools. The toolbox has waterproofing strips inside.

3. The trailer uses an aluminum alloy air tank, reducing weight while ensuring clean and uncontaminated compressed air, guaranteeing the proper functioning of the valves and pumps in the trailer's braking system.

● Striving for Excellence: A Balance of Practicality and Aesthetics

The front beam has all the electrical and pneumatic connections installed tightly, giving it a very neat appearance.

End Beam Corner Comparison:

The front and rear end beams of the Hezhong skeleton trailer feature rounded corners, ensuring the strength of the lock base and preventing injury to others. This rounded corner design also greatly enhances the trailer's aesthetics. Common skeleton trailers have right-angled ends on the front and rear end beams, which are not only unsightly but also pose a significant risk of injury.

In addition to the front and rear end beams, the locks on other crossbeams have outer shells at the bottom, further enhancing the overall aesthetics of the vehicle. In contrast, other skeleton trailer have locks that are directly exposed, lacking in aesthetics.

The areas where the wiring passes through the crossbeams are prone to wear and tear. These easily worn wiring routes have been wrapped to prevent wear and tear. The attention to detail is commendable, demonstrating Hezhong Trailer's rigorous approach to vehicle manufacturing.

At the axle location, let's examine the electrical and pneumatic circuit layout of this trailer. The photos show that all the wires are bundled together, indicating a very neat and orderly wiring layout.

The trailer's suspension balance beam is galvanized to prevent rusting during normal use. Additionally, the balance beam pins are also galvanized; according to reports, the Hezhong trailer's balance beam pins are designed for maintenance-free operation.

The locks used to secure the containers are also galvanized for enhanced corrosion resistance. The spare tire rack, toolbox, guardrails, and side light connectors are also galvanized to prevent corrosion and extend their service life.

● Robust Chassis Ensures Reliable Daily Use The above mainly introduced the welding and some details of the trailer. Next, we will introduce the chassis of this skeleton trailer.

Since it is a skeleton trailer, it uses Fuwa brand trailer outriggers. For container transportation that frequently requires attaching and detaching, good trailer outriggers make daily use more convenient.

The axles are custom-designed German-style axles by Hezhong, ensuring high reliability and meeting the needs of container transportation. The wheels are steel rims with Goodyear tires, all top-quality products, providing better performance for the trailer.
