SUNSKY TRAILER, I believe many people have heard of it or seen it on the road. Thanks to its excellent workmanship and light and durable quality, it is deeply loved by users. Last year, the sales volume of SUNSKY TRAILER exceeded 5000.

SUNSKY recently introduced a new trailer, which is a 40-foot skeleton semi-trailer used for container transportation. SUNSKY produced the container skeleton semi-trailer, I believe that there must be some distinctive design, what are the specific highlights? Let's take a look.

It is weigh only 5.3 tons, which is more than 300 kilograms lighter than its competitors. The vehicle can transport one 40-foot container or two 20-foot containers. In addition to the advantages of weight, this container frame trailer has many highlights. The quality of a trailer depends more on the details of the workmanship, mainly reflected in the design, welding, line layout and other aspects. Therefore, we will focus on the production process and lightweight design of this trailer.

◼️  First look at the details of the welding coating is quite good

This skeletal trailer has a common yellow coating, which is very eye-catching. Red and blue can also be sprayed. Although the matte paint surface is not very bright, it is evenly sprayed, and the whole trailer has a good texture.

Below the yellow topcoat is the electrophoresis primer. This trailer adopts the electrophoresis process. After the shot blasting and rust removal, the trailer will undergo electrophoresis. After electrophoresis, there will be a layer of electrophoretic paint, which will greatly enhance the anti-corrosion ability of the trailer.

Welding process comparison

The quality of the trailer is good or bad, the welding process is very important. The beam welding of skeleton trailer is smooth and uniform, which indicates that the welding process is good. This skeleton trailer adopts robot welding. Compared with manual welding, there will be no convex or uneven weld, and robot welding can guarantee the welding strength and aesthetics to the maximum extent. At the same time, robot welding also greatly reduces the welding time of the whole vehicle and improves the production efficiency.

Let's take a look at the hidden position inside the girder. The weld seam is smooth and uniform, which indicates that the welding process of this skeleton trailer is the same inside and outside. The welding of the whole trailer is very good.

◼️  Unique design to ensure the strength of the weight reduction

In this skeleton trailer, we found a lot of lightweight design, although each one can not reduce the weight of a lot, but together into a tower, the overall weight reduction effect is obvious. According to the introduction of the manufacturer, the dead weight of this trailer is only 5.3 tons, while the same type of trailer of other manufacturers is basically above 5.6 tons, so it has obvious advantages in dead weight. If this trailer replace aluminum wheels, the weight can also be reduced by more than 200 kilograms.

What are the specific lightweight designs of SUNSKY TRAILER? Let's move on.

The webs of the trailer girder are designed with multi-channel stiffeners to increase the strength of the trailer girder. Different from other manufacturers, the stiffeners of this trailer are designed more rationally to ensure the strength of the girder while reducing the weight. In addition, there are notches at both ends of the stiffeners to release the stress during loading. Due to the large bearing capacity at the suspension leg, the suspension leg of the trailer is also equipped with reinforcing ribs to enhance the strength of the suspension girder.

Beam support contrast

This trailer of SUNSKY adopts variable cross section beam, and the support is made of high-strength steel plate. The round hole on it is to reduce the weight. Compared with the channel steel beam and channel steel support adopted by other manufacturers, the weight can be reduced on the premise of ensuring the lightness.

Suspension girder reinforcement comparison

Round hole stamping and reducing dead weight

In the suspension position of the trailer girder and the bridge, this trailer uses the lower wing plate and the web to strengthen the design, which can reduce the dead weight of the trailer girder under the premise of ensuring the strength. At present, the common skeleton trailer uses a layer of web to increase the strength of the girder, such a design can be said to be another highlight of SUNSKY skeleton trailer.

In the trailer beam at the leg, we found a flanged design. The advantage of this design is that there is no need to add additional beams to meet the strength requirements.

leg beam lowers its weight

In order to achieve the lightweight of the whole vehicle, this skeleton trailer uses a lot of aluminum accessories, the purpose is to reduce the weight of the trailer.

1. At both ends of the trailer, aluminum alloy guardrail is used, which reduces the weight and is more beautiful, and there is no corrosion.

2. There is an aluminum alloy toolbox on the right side, which is convenient to carry some tools with the trailer. There is an adhesive strip inside the toolbox, which can play a waterproof role.

3. Aluminum alloy air storage cylinder is used in the trailer, which can reduce the dead weight and guarantee the clean compressed air from being polluted, and ensure the normal operation of the valve and pump of the trailer brake system.

◼️  Keep improving on practicality and aesthetics

In the front beam, the circuit, gas road joint installation is close, looking to give a person a very neat feeling.

Angle contrast of end beam

The front and rear end beams of SUNSKY skeleton trailers are designed with rounded corners to ensure the strength of the lock base and avoid hurting others. In addition, such rounded corner design, the beauty of the trailer will be greatly enhanced. The two ends of the front and rear end beam of the common skeleton car are right-angle structure, which is not beautiful but also easy to hurt others.

In addition to the front and rear end beams, there are enclosures at the bottom of other beam locks, further enhancing the aesthetics of the vehicle. While other skeleton trailer for the lock directly leakage, lack of aesthetic.

joints

The parts where the lines pass through the beams are prone to wear. The layout of these easily worn lines is wrapped to prevent the lines from being worn. The details are well handled, which shows that SUNSKY has a very rigorous attitude towards vehicle building.

In the axle position, let's take a look at the layout of the circuit and gas path of this trailer. From the photos, we can see that all the circuits are tied together, and the layout of the circuit of this trailer is very neat.

rigorous circuit

In the trailer hanging balance beam, this trailer is galvanized balance beam, can prevent rust in the daily situation. In addition, the balance beam pin is also galvanized. According to the introduction, the SUNSKY TRAILER beam pin is designed to be maintenance-free.

The locks used to fix the containers are also galvanized to enhance the anti-corrosion ability. Spare tire frame, toolbox, guardrail, side lamp connection also use galvanized treatment, avoid future use of corrosion, prolong the service life.

◼️  Chassis stability is good, daily use is guaranteed

The above has mainly introduced the welding of the trailer in some details. Next, we will introduce the chassis part of the skeleton trailer.

Because it is a skeleton trailer, so the use of Fuwa brand trailer leg, for often need to pick hanging container transport, a good trailer leg more convenient for daily use.
