First of all, let's take a look at what is a centre-axle trailer. As the name implies, a centre-axle trailer is a trailer with an axle in the middle. The trailer we often see now is the semi-trailer with the axle at the rear. The axle in the middle of the trailer is a centre-axle trailer. If the axle is at both ends of the trailer, it is a full trailer. Because the axle of the centre-axle trailer is in the middle, the balance of the trailer cannot be maintained, and the trailer leg is required to maintain the balance.First of all, let's take a look at what is a centre-axle trailer.

Due to the different design of vehicles, the towing position of the centre-axle trailer is different from that of the semi-trailer. The full trailer is connected to the main vehicle through the towing hook installed on the main vehicle frame, while the towing hook connected to the main vehicle by the central axle trailer is located under the frame.

Semi-trailers need to be connected with the main vehicle through the tractor bridge, and the main vehicle needs to bear the weight of the trailer. Because the axle of semi-trailers is generally only in the rear half of the trailer, the weight of the front half of the trailer must be borne by the tractor.

There are many types of semi-trailers, most of which are in the form of special vehicles, such as ordinary railings, semi-trailers of warehouse railings, semi-trailers of coal haulage, semi-trailers of dump trucks, semi-trailers of low platform, semi-trailers of container platform, semi-trailers of container container frame type, semi-trailers of van type and special semi-trailers.
The centre-axle trailer is not suitable for heavy load transportation of goods. The axle is in the middle of the trailer. If the weight of the goods pulled by the trailer is too large, the centre-axle trailer is not easy to maintain balance.
The main advantages of semi-trailer are its strong heavy-load capacity, ability to pull heavy goods, good high-speed driving stability, easy to match with tractor, and the driving difficulty is much lower than that of mid-axle trailer.
Middle-axle trailers are more common in foreign countries than in China, and the road freight environment in foreign countries is very good compared with that in China, which can be used on any road. In some countries, the number of full trailers is even the same as that of semi-trailers. Most of the domestic mid-axle trailers are used in caravans or small trailers. In terms of freight transport, semi-trailers are mainly used.
The latest GB1589 stipulates that the length of the mid-axle car can reach 22 meters. This action will promote the development of the mid-axle car in China.
The tonnage that a trailer can carry depends mainly on the axle of the trailer. If the axle is of good quality, it can carry more goods. The American-style axle manufactured by Hongkai mechanical parts is designed to be simple in structure and durable. Hongkai Machinery Parts Manufacturing Co., Ltd. has built 22000 ㎡ standardized workshop, laid the industry-leading automated intelligent production line, introduced the latest high-precision quality inspection instruments, and strictly implemented the IATF16949 quality system standard. Check the product quality at all levels to ensure that each axle is qualified.
