On September 21, the new version of the over-limit overload management regulation was implemented to limit the total height of the vehicle to 4 meters, with the exception of the skeleton trailers for shipping international standard containers. As far as the current in-use vehicles are concerned, the saddle height is generally around 1.3 meters. Coupled with the height of the trailer's girder, the cargo space is compressed. In the face of increasingly stringent laws and regulations, a reasonable reduction of the chassis height is imperative.
â— How to lower the chassis height of domestic trucks is a problem
In accordance with the new version of GB1589 and the new version of the overload limit certification regulations. The total height is limited to 4 meters. This will lead to the delivery of ultra-high vehicles carrying international standard containers. Therefore, in GB 1589, the height of the tractor saddle for transporting international standard containers was restricted. The height of the saddle seat should not exceed 1320mm for transporting 2591 TEU containers, and 1110mm for transporting 2896 high cabinets. At present, domestic sales of trucks are usually relatively high in the chassis, most of which are around 1.3 meters. There is an ultra-high phenomenon when transporting high cabinets.
For retailers and logistics companies, the chassis height also affects an important factor in the volume of cargo, because your cargo cannot be heavy cargo. In LTL logistics, re-allocating foam is a common loading method and a high degree of restrictions. Undoubtedly, the volume of the bubble cargo was reduced. For the express delivery industry, the height of the chassis involves the size of the compartments. This is even more important for the express delivery industry, which focuses on light-bubbles. How to reasonably reduce the chassis height is the current problem.
â— further reduction of the tires on the chassis
In the traditional form of suspension, there is little hope of lowering the height. At present, the airbag suspension that can effectively reduce the height of the chassis has reached its limit, but the overall size is still high due to the size of the tire. In terms of suspension alone, basically there is no potential to dig. However, the current road conditions and weight restrictions have also begun to be strict. The feasibility of thinking on the tires has improved. In Europe, there is already such a low chassis tractor.
I also discovered this model when I was at the Hanover Motor Show last month. Other configurations have not changed, but I have adopted a small flat tire with 315/45R22.5. The height of the vehicle is adjusted by the airbag suspension. The saddle height The minimum is only 910mm. As a result, the cargo space is increased within a limited height. If equipped with a carrier-type trailer, meeting the needs of the express delivery industry is completely without problems.
Similarly for the LTL logistics, the lower chassis, together with the loaded car, can also get more cargo space and will also reduce its own weight. In China, for the express delivery business, some manufacturers have also introduced 6x2 vans equipped with small flat tires. It is difficult to say whether this change will be transferred to the LTL logistics, but it is reasonable to pursue the maximization of the load. The trend of the truck in the future.
â— Postscript
With the increasingly stringent laws and regulations, how to obtain more cargo space in the wired space will be the trend of future truck development. Trucks that reasonably lower the height of the chassis are also bound to reduce the vehicle's own weight, which will increase from the volume of the cabin to the weight of the load. Coupled with the promotion of dumping, exchange boxes, and multimodal transport, logistics will surely go in the direction of low cost and high efficiency.
Some people call seamless pipe as Seamless Steel Tubes, on the surface, we will not find weld seam. According to manufacture process, seamless pipe is divided into hot finish & cold drawn.
Specifications for seamless pipe
1. OD:Hot finish:2``-30``, cold drawn:0.875``-18``
2. WT:Hot finish:0.250``-4.00``, cold drawn:0.035``-0.875``
3. Length:Random length, fixed length, single random length (SRL), double random
length(DRL).
4. Surface treatment:Transparent oil, rust-proof black oil or hot galvanized Steel Pipe
