Detailed explanation of low bed semi-trailer: a comprehensive guide from standard to special vehicle models

Low bed semi-trailer, as a member of the semi-trailer family, occupies an indispensable position in the transportation field due to its unique cargo loading characteristics. Its tabletop design is relatively low, allowing it to adapt to a wider range of heights when transporting large goods, thus winning widespread favor. Whether it's earthmoving machinery, agricultural machinery, building materials, or industrial raw materials, low bed semi trailers can easily handle them and become a star model in the transportation industry.

Regarding the relevant standards for low bed semi trailers, the current reference is JT/T 1284-2020 "Technical Specification for Low bed Semi trailers" issued by the transportation industry. Since its release on February 28, 2020, this standard has been implemented since April 1, 2020, providing comprehensive guidance for the design, production, inspection, and use of low bed semi trailers. The standard specifies in detail the general technical requirements, special requirements, test methods, inspection rules, as well as requirements for identification, on-board documents, and storage of low bed semi trailers, ensuring the quality and safety of low bed semi trailers.

In addition, low bed semi trailers are further divided into two types in the JT/T 1284-2020 standard: low bed dedicated semi trailers and low bed enhanced semi trailers. Among them, the low bed enhanced semi-trailer is based on the low bed dedicated semi-trailer, and further enhances its carrying capacity through structural strengthening and functional expansion. This type of semi-trailer not only has the basic functions of a low bed semi-trailer, but can also be used for the transportation of special large objects such as ultra wide and overweight, meeting more complex and demanding transportation needs.

In addition, there are different classifications of low bed semi trailers in foreign countries. They usually divide common low bed semi trailers into two categories: Step pack Trailers and Lowboy Trailers. Among them, the loading platform of the Step pack Trailer is in a stepped shape, with the head platform higher than the rear complete loading platform, which facilitates the loading and transportation of auxiliary components of the main body. Lowboy Trailer, on the other hand, pays more attention to the height and weight restrictions of the cargo. Its loading platform height is generally lower than the height of the trailer tires, making it suitable for transporting heavy goods.

The height of its loading plane is designed to be quite low, almost equal to the axis height of the trailer axle, presenting a goose neck style feature. When loading goods, it is usually necessary to separate the gooseneck part of the front of the vehicle from the trailer body at the rear in order to carry out loading operations from the front. In addition, to drive the hydraulic system of the trailer itself, an independent power source will be equipped above the gooseneck. Compared to the "Step pack" semi-trailer, the loading platform height of the Lowboy Trailer is lower, making it particularly suitable for the transportation needs of ultra wide and ultra high special large objects.

Detailed explanation of key parameters for low bed semi-trailer

When choosing a low bed semi-trailer, the configuration of key parameters is the key factor determining its quality. Next, we will delve into several core parameters that affect the quality of low bed semi trailers.

Firstly, the overall dimensions of the vehicle are the fundamental indicators for measuring the performance of a low bed semi-trailer, including length, width, and height parameters. Generally speaking, the length range of a low bed semi-trailer is set from 13 meters to 13.75 meters, the width is maintained at 3 meters, and the height is 1.75 meters. This size design not only meets transportation needs but also ensures driving safety.

Secondly, the specification of longitudinal beams is an important basis for measuring the load-bearing capacity of low bed semi trailers. It is determined by multiple parameters such as height, upper wing plate, lower wing plate, and web plate. There will be significant differences in the load-bearing capacity of longitudinal beams of different specifications, mainly reflected in the thickness of the upper and lower wing plates and web plates.

In addition, other configurations of the semi-trailer, such as legs, synchronizing valves, leaf springs, axles, and tires, also have a significant impact on the overall quality of the semi-trailer. When choosing, these configurations can be flexibly selected according to personal needs and budget.

At the same time, we should also pay attention to avoiding the situation of "picking sesame seeds and losing watermelon" in configuration selection. Good vehicle configurations are often complementary, for example, high-quality axles can significantly reduce long-term tire wear, while lightweight configurations such as aluminum alloy wheels can save considerable costs in daily transportation.

Finally, we will provide a detailed presentation of different types of low bed semi trailers, including gooseneck low bed semi trailers and special low bed semi trailers, while also exploring the load capacity of low bed semi trailers with different axle numbers and tire sizes.
