In China's road freight, in addition to gooseneck flatbed trailers suitable for diversified transportation, presumably more practical and more practical warehouse grid trailers have also made card friends full of praise. In particular, the current stringent over-limit and overload control measures have caused many card friends who are engaged in coal, agricultural products, and less-than-carload general cargo transportation to turn their attention to this model that focuses on lightweight design.
▎Mainstream warehouse grid type trailer type:
Beginning in 2018, the relevant domestic road transport policies began to implement the new 49-ton (6x4) and 46-ton (6x2) vehicle load standards for six-axle trailers, and the 13m barn-type trailers of major brands have successively adopted the improvement of lightweight materials. Designed to reduce the weight of the previous 8 tons to 6.5-7 tons.
● 13m straight beam type:
The biggest difference between the straight beam warehouse trailer and the ordinary 60 cm fence trailer is that the grid guardrail is installed above the fence, and the airtight soft canvas is installed in the later stage, which has stronger professionalism for transporting bulk cargo such as corn and wheat. At present, the weight of lightweight vehicles is controlled at around 6.5 tons.
● 13m gooseneck type:
The gooseneck trailer is a practical vehicle that is very popular among individual transporters at present. Its biggest feature is that the force of the three-axle tires is still even when the trailer is heavily loaded, which can increase the volume of 2m³ compared with the flatbed trailer when transporting bulk goods. The weight of the lightweight vehicle has been reduced from the previous 8.3 tons to 6.8 tons.
● 10m flat panel type:
Transportation companies and individuals in major coal producing areas such as Hebei, Shanxi, and Shaanxi usually choose a barn-grid trailer with a total length of 10m. The short-wheelbase design has better practicality for vehicles traveling on national roads throughout the year. .
Due to the lightweight warehouse grid design, the weight of the vehicle is 500 kg less than that of the semi-open type, which means that this type of vehicle will increase the transportation capacity by 1 ton for round-trip full-load transportation, thereby increasing transportation revenue.
"Grounding gas" has always been the driving force for the sustainable development of domestic commercial vehicles. The highly adaptable warehouse-type trailers are suitable for the strict over-limit and overload control policies currently implemented in my country, and have a promoting effect on the continuous development process. In addition to the four barn-grid trailers introduced above, the similar models to be introduced next will definitely open up the eyes of card friends.
▎Detailed explanation of 9.5m warehouse grid trailer:
Recently, I saw a 9.5m short-wheelbase warehouse-type trailer waiting to be licensed in a certain area in Shandong. This vehicle is a niche product compared to 13m models of the same type. In conversations with the owner, I learned that this area is the main producing area for vegetables such as cabbage and radish. This short-wheelbase semi-trailer vehicle can drive more flexibly in the fields.
This model adopts a gooseneck design with a more stable driving, which reduces the unstable situation of driving due to a high center of gravity of a full load. The vehicle has a length of 9.5m, a width of 2.55m, a maximum height of 3.9m, and a curb weight of 5.7 tons.
For such non-drop-and-trail vehicles, hand-cranked outriggers with higher economic efficiency and reliability are still appearing as the mainstream. Even with such a short wheelbase design, the middle position of the axle and the outriggers is still equipped with a horizontal guardrail that is convenient for the driver to get on and off the vehicle.
The edge of the railing box is equipped with a rope tightening device that is standard on the trailer, which is convenient for rotating and tightening the rope to ensure the tightness of the tarpaulin during driving; in addition to the open-down design of the railing box, the upper two sides of the warehouse fence The multi-layer and open-out design of the container is mainly designed to improve the efficiency of vegetable loading and unloading.
