The adaptability of full trailers under complex road conditions is more complex. It has both unique advantages and some limitations. The following is a specific analysis:
Advantages
1. Better passability: The turning radius of full trailers is smaller than that of semi-trailers. On some poor road conditions, the vehicle has better passability. For example, in complex road conditions such as narrow streets and rugged mountain roads, it can turn and turn around more flexibly to avoid collisions with other vehicles or obstacles.
2. Strong independent load-bearing capacity: Full trailers can bear weight independently and maintain balance after being separated from the main vehicle, which makes it more convenient to load and unload goods, reduces the waiting time of the main vehicle during the loading and unloading of the trailer, and improves transportation efficiency. It is especially suitable for some complex scenes that require frequent loading and unloading of goods.
3. Wide range of applicable scenarios: Full trailers play an important role in closed transportation environments such as coal yards, docks, warehouses, mines, and stations. In addition, under rugged road conditions in agriculture, animal husbandry and other fields, they can also undertake some short-distance transportation or special operations, such as transporting large agricultural machinery and agricultural products.
Limitations
1. Difficulty in driving: Since the front axle of a full trailer generally has a steering function and is relatively independent of the steering system of the main vehicle, the tracking performance of the trailer is not as good as that of a semi-trailer. This is a test of the driver's skills and psychological quality, especially when reversing, the driving difficulty is even greater, and if you are not careful, you will lock yourself up, and only experienced drivers can do it.
2. Poor driving stability: The traction rod/traction frame of the full trailer can swing up and down, and can swing left and right, which enhances the flexibility of the full trailer, but also greatly affects the stability of the full trailer at high speeds, which is easy to cause dangers such as braking and tail swinging, so it is not suitable for high-speed transportation.
3. Unstable braking distance: The connection between the full trailer and the main vehicle is mainly through the traction rod/traction frame, and the gap in the middle is not fixed. The synergy of the trailer is not as good as that of the semi-trailer. Therefore, it is also a great test of the driver's skills and experience when braking. If the brakes cannot be stepped on in a timely and stable manner, it is easy for the vehicle to tail swing, and it is also easy to brake and slip in rainy and snowy weather, affecting traffic safety.
