In the world of semi-trailers, landing gear is often overlooked but is an extremely crucial component. Today, let's take a deep dive into the role, types, and importance of semi-trailer landing gear during the transportation process.

Firstly. The Role of Semi-Trailer Landing Gear
Semi-trailer landing gear mainly serves to support the semi-trailer. When the semi-trailer is separated from the tractor, the landing gear can firmly support the front part of the semi-trailer, preventing the vehicle from tilting or collapsing. This is crucial for the safe loading and unloading of goods as well as the parking of the vehicle.

In addition, in some special situations, such as when the semi-trailer needs to be repaired in the wild or is waiting for rescue, the landing gear can ensure that the vehicle remains stable and provides a safe working environment for operators.

Secondly. Types of Semi-Trailer Landing Gear
1. Built-in Landing Gear
Built-in landing gear is a supporting device installed inside the semi-trailer. It is usually divided into fast and slow gears. When the tractor and trailer are uncoupled, the built-in landing gear can quickly support the front half load of the semi-trailer.
The advantage of built-in landing gear is that it does not occupy external space, making the appearance of the semi-trailer neater. At the same time, since it is installed inside, the built-in landing gear is relatively safer and less likely to be damaged by external collisions.
2. External Landing Gear
External landing gear uses a screw lifting mechanism and is divided into high and low gears. It has a steel ball positioning mechanism and a sliding shifting mechanism. The high-speed gear is fast and time-saving when unloaded, and the low-speed gear is easy to operate and labor-saving when loaded.

The advantage of external landing gear is that it is more convenient to operate. The driver can easily adjust the height of the landing gear outside the vehicle. In addition, the support force of external landing gear is usually relatively large and can adapt to heavier semi-trailers.

Thirdly. The Importance of Semi-Trailer Landing Gear
1. Ensuring Cargo Safety
The stable support of semi-trailer landing gear can ensure that the goods will not be damaged due to the tilting of the vehicle during the loading and unloading process. Especially for some fragile and valuable goods, the role of landing gear is even more important.
2. Improving Transportation Efficiency
Stable semi-trailer landing gear can reduce the time for loading and unloading goods and improve transportation efficiency. At the same time, during the transportation process, if the semi-trailer breaks down and needs repair, the landing gear can also provide a stable working platform for maintenance personnel and speed up the repair progress.
3.  Ensuring Driving Safety

During driving, if the landing gear of the semi-trailer malfunctions, it may lead to dangerous situations such as vehicle tilting and cargo scattering. Therefore, regular inspection and maintenance of semi-trailer landing gear to ensure its normal operation is crucial for ensuring driving safety.

Lastly. How to Choose and Maintain Semi-Trailer Landing Gear
1. Choose the Appropriate Landing Gear Type
When choosing semi-trailer landing gear, you need to select the appropriate type according to your actual needs and usage situations. If you have high requirements for space, you can choose built-in landing gear; if you need more convenient operation and greater support force, you can choose external landing gear.
2. Pay Attention to the Quality and Brand of Landing Gear
Choosing reliable quality and well-known brand semi-trailer landing gear can ensure its stable performance and long service life. At the same time, when purchasing landing gear, also pay attention to checking the product quality certification and after-sales service.
3. Regularly Inspect and Maintain Landing Gear
To ensure the normal operation of semi-trailer landing gear, it needs to be inspected and maintained regularly. Inspection contents include whether the appearance of the landing gear is damaged, whether the screw lifting mechanism is flexible, and whether the steel ball positioning mechanism is normal. If any problems are found, they should be repaired or replaced in time.

In conclusion, although semi-trailer landing gear is a small component, it plays a crucial role. When choosing and using semi-trailer landing gear, we need to fully consider its role, types, and importance, select the appropriate landing gear type, and regularly inspect and maintain it to ensure the safe and stable operation of semi-trailers.
