What kind of semi-trailer is used to pull coal?

Our country is the coal production and consumption big country, coal transportation has always been one of the source of freight of northern trailer, especially to heating season, the demand of coal also increases accordingly, some owners seemed to see a business opportunity, want to join them, but to the transport vehicle of each of the models is made difficult: After all which kind of semi-trailer is more suitable to transport coal?

Under normal circumstances, pulling coal semi trailer needs to have excellent bearing capacity and driving force, and the tractor chooses the double drive type more. As for semi-trailer, the general requirements to prevent dumping, easy loading and unloading, summed up is "loading + unloading", currently mainly divided into self-unloading type and van type:

1. Self-dumping semi-trailer.

Especially suitable for coal, ore, building materials and other goods transportation. In terms of structure, the self-dumping semi-trailer usually adopts the rollover and back-rollover self-dumping mode, which can improve the transportation efficiency of scattered goods. Its frame and carriage rail have the advantages of high strength and strong lifting force, which can not only undertake engineering transportation tasks, but also undertake the transportation tasks of light and medium loose goods.

2. Van semi-trailer.

Coal can also be transported by van semitrailers. Compared with dump semitrailers, the biggest advantage of van is the closure of the carriage, which can reduce the impact of the goods due to the environment or weather. The top has closed, push and pull open, open, open to tarpaulin rod type, can meet different transportation needs.

Although there are no special requirements for coal trailers, as cargo vehicles, load-bearing, braking and other safety performance must be fully up to standard. Especially with the increasing competition in the coal transportation industry, the vehicle maintenance cycle must also be taken into consideration.

At present, most of the domestic tractor-trailer engine maintenance mileage can reach 100,000 kilometers, transmission maintenance cycle can reach 200,000 kilometers, drive axle maintenance mileage of 100,000 kilometers, basically can meet the needs of owners, but with the tractor, the semi-trailer walking unit maintenance cycle many still stay in 20-30,000 kilometers, and the tractor maintenance cycle is seriously mismatched, Even if the tractor is in good condition, the trailer will be out of service once it is maintained.

As an important part of trailer walking unit, trailer axle upgrade is urgent. DARO Heavy Industry Group is the first Liangshan began mass production of integrated shaft tube enterprises, with 20 years of industry experience, in the trailer axle lightweight design, heavy load enhancement and maintenance cycle extension and other fields have made great progress, DARO Group production of trailer axle compared to the traditional products reduce the weight of 15-20%, maintenance cycle can be extended to 2 years or 50,000 kilometers, durable and resistant, Strong load, with excellent quality and high cost performance in the industry has accumulated a good reputation.
