How much weight is the light semi trailer?

With the increase of the national control of overload and the implementation of the weight charge policy, the heavy semi trailer has gradually deviated from the development trend of the industry, especially after the introduction of GB1589, the carrying weight of the semi trailer has changed a lot, from the original 55t to 46-49t, in order to achieve more cargo under the premise of not overload, the vehicle lightweight is the key.

The lightweight semi trailer is a product of the lightweight trend. Light semi-trailer refers to a lightweight semi-trailer, the most important difference with ordinary semi-trailer is the weight, in the case of load, model and size, light semi-trailer can be more than 15% lighter than the same specification of semi-trailer.

Although the weight has been reduced, the cargo capacity has not changed. Take the 13-meter semi-trailer as an example. Ordinary semi-trailers generally have a dead weight of 6.8t and can carry 34t of cargo, while light semi-trailers have a dead weight of 5.3t-6.3t and carry the same amount of cargo as ordinary semi-trailers. It can reduce the weight of the vehicle without affecting the safety performance of the vehicle, which is one of the reasons for the emergence of light semi-trailer. Less weight, more cargo, less fuel consumption, and more economic benefits for the owner of a light semi.

What are the main means to achieve weight reduction of light semi trailer?

1, reduce the thickness of the plate: the use of high standard steel, high strength, good toughness, fatigue resistance, low weight.

2, reduce the rear axle weight: the trailer axle plus suspension is close to two tons, by reducing the rear axle weight can also reduce the weight.

3. Replace the suspension: replace the steel plate suspension with air suspension.

4. Reduce the weight of accessories: use lightweight vehicle accessories.

5, the suspension rear axle: when not in use can be lifted to reduce self weight.

Thus, it can be seen that the selection of a lightweight axle and suspension is a common way to achieve weight reduction of light semi-trailer, such as the disc axle with air suspension. The main product of DARO Heavy Industry Group is 13t disc axle, which is the representative of lightweight axle. In terms of raw materials, low-alloy seamless steel pipe is selected, and the mechanical properties of castings are fully activated by the integrated heat treatment of shaft tube + one-time cold thrust square technology. In terms of appearance, shaft tube adopts square design, and local reinforcement treatment, wear resistance, crack resistance and high strength bearing capacity. Mechanical performance is greatly improved, with DARO's air suspension, can provide safer and more stable protection, to help owners adapt to the strict transportation environment of weight charging and double control.
