2. What is the purpose of the sidewall semi trailer?

The sidewall semi trailer is evolved on the basis of the container flatbed trailer, and the loading part has a sidewall design structure. Because of its complete functions, strong adaptability and simple operation, it has become the first choice for road freight trailers. 40 ton bulk transport trailer, 60 ton sidewall semi trailer, and 80 tons dropside cargo trailer can be used to transport a wide variety of products or materials, from wooden boxes to other bulk cargos. The sidewall of the trailer can be flexibly opened or disassembled, which is convenient for loading and unloading large cargo.

3. Main components of YUHANG sidewall trailers

1. Sidewall semi trailer frame: the frame is the main and important part of the vehicle’s load-bearing, consisting of main beams (welded I-beams), supporting beams, connecting beams, side beams and inclined brackets.

2. Sidewall structure: the sidewall is divided into straight or vertical corrugated boards. Vertical corrugated boards are a typical style with relatively high compressive strength. The sidewalls are generally detachable, and if we want to be stronger, we can also directly weld the sidewalls and the frame as a whole.

3. King pin of the sidewall trailer: the king pin is an important part connecting the sidewall trailer and the tractor. The king pin is generally forged from chrome alloy steel, and there are 50# and 90# king pin.

4. Suspension system: it is mainly used to support the load and reduce the vibration energy when the vehicle is heavily loaded. There are three commonly used suspensions: leaf spring suspension, single-point suspension, and air suspension. Among them, leaf spring suspension is more common and the cost is relatively low.

5. Axle and tire: the axles are connected to the suspension system through leaf springs, and most of the force during the driving process of the vehicle needs to be borne by the axles and tires. The axles we are currently using are FUWA or BPW brand.

6. Electrical system: the electrical system of the dropside trailer consists of seven-core sockets, cables, air circuits, and various lamps, which are used for lighting, safety warnings, and air supply for brakes.

7. Landing Gear: it is mainly used to support when the sidewall semi trailer is separated from the tractor. There are single-action and linkage types landing gears for you to choose.

8. Braking system: the triaxle sidewall semi trailer adopts a two-line pneumatic braking system and is equipped with ABS to ensure that there will be no problems during driving.

9. Protection device: the protection device is composed of side protection and rear protection, which can protect the safety of pedestrians and other vehicles, and can also reduce the air turbulence on both sides during driving, and play a role in reducing wind resistance.

10. Sidewall trailer accessories: other accessories include toolbox, spare tire rack, rope tensioner, and rope hook, which can be selected according to your own requirements.

4. Specifications and load capacities of sidewall cargo trailers

The loading capacity of the sidewall cargo trailer is very important, which is related to whether your transportation business can be carried out normally. The easiest way is to look at the weight of the sidewall cargo semi trailer. The heavier the weight, the better the quality and the stronger the trailer’s carrying capacity.

1. The thickness of the main girder of the YUHANG sidewall cargo trailer is 14/8/16mm according to the international standard. The steel plate in the middle of the beam is made of Q345B manganese steel with a thickness of 8mm. Many unreliable suppliers will choose a steel plate with a thickness of 6mm to save costs, which will greatly reduce the bearing capacity of the main beam.

2. The bottom plate of the YUHANG sidewall trailer adopts the international standard 3mm thick anti-slip and wear-resistant pattern plate, which will ensure that our cargo transport trailer is more durable and has a longer service life.

3. The height of the side door can be 600mm, 800mm, 1000mm, which will also affect the loading capacity of the trailer.

All in all, our dropside trailers can carry 20-100 ton bulk cargos, which is very easy to do. If you have more transportation requirements, you can tell us the properties of the goods to be transported and the local road conditions, and we will provide you with professional advice or design and customize sidewall cargo trailers.

11. Precautions during use of sidewall semi-trailer

1. Oil replacement knowledge

How often should the oil be changed? How much oil should be changed each time? We pay special attention to the replacement cycle and consumption of engine oil. Generally speaking, the replacement cycle of engine oil is 5,000 kilometers. The specific replacement cycle and consumption should be judged according to the relevant information of the cargo transport trailer. When replacing the engine oil, it is necessary to replace the oil filter together.

2. Knowledge of antifreeze application

Antifreeze is used throughout the year. In addition to the function of antifreeze and cooling, antifreeze also has the functions of cleaning, rust removal and anticorrosion, which can reduce the corrosion of the water tank and protect the engine. Note that the color of antifreeze should be selected accurately and not mixed.

3. Knowledge of brake fluid application

The function of the brake system is closely related to the brake fluid. When checking and replacing hardware such as brake pads and brake discs, don’t forget to check whether the brake fluid needs to be increased or replaced.

4. Transmission oil

In order to ensure that the car turns sensitively, it is necessary to check the transmission oil frequently. Whether it is gear oil or active transmission oil, pay attention to the type of oil.

5. Further maintenance of lubrication system

The primary function of the lubrication system is to effectively lubricate the various components of the sidewall trailer engine and prevent excessive wear. Clean the sludge and other accumulations inside the engine, prevent the oil from oxidizing and thickening at high temperature, reduce the wear of engine parts, prolong the life of the engine and increase the power of the engine.

12. Post-maintenance tips for cargo trailers:

Safe driving is the top priority. In order to prevent problems before they happen, drivers should be diligent in maintaining and checking the sidewall cargo trailers. Here are some maintenance tips:

1. Visually inspect the tire pressure, check whether the tire is deflated or leaking, and then check whether the wheel hub is deformed or cracked.

2. Check the tightness of the tire screws. Don’t bother with this detail. You should check whether each screw is tight to avoid safety accidents.

3. Make sure the landing gears are normal. To check the landing gears, shake them up and down a few times to see if there are cracks in the welding.

4. Check the box boards, lock rods, reach out and touch the box board hinges, box hooks, stakes, container twist locks and other small parts to see if there are any cracks or breaks.

5. Check all lamps and reflective markers and electrical circuit systems.

6. Check the braking system, listen to the sound of air leakage, and test the braking effect.
