Masters, help. I want to buy a semi-trailer.

Run high speed, good road conditions, pull the standard load, and be elected as Tianlong tractor. Tianlong Cummins engine runs fast and saves fuel, and can put 120 mph or more. Now it has a Renault engine.

The weight of the car body is about 8.5 tons, and the 340-horsepower dual-drive 275,000 Renault engine after Tianlong will do.

My friend just ordered one. Single-drive uphill climbing is not as powerful as double-drive climbing.

Only the distribution is selected as13m lightweight warehouse column, and there is no 13.5 as you said.

As the name implies, an ultra-light semi-trailer is a much lighter car than an ordinary car. How much lighter? The definition in the industry is that cars with the same weight, the same size and the weight less than 15% are defined as ultra-light.

There are several things that semi-trailers can do to reduce weight:

1. Reduce the thickness of the plate. This can be made of high-grade steel. High strength standard steel, high strength, good toughness and fatigue resistance.

2. Reduce the weight of the rear axle. Axles and suspensions are now close to two tons, as well as light bridges, disc brakes, four leaf springs and new ones.

T-type lifting lug, vacuum tire and single tire are all effective methods.

3. Change the suspension. Only airbag suspension is needed, which is rarely used.

4. Reduce the weight of accessories. Reduce the weight of bumper, side guard net, mesh spare tire rack, tool box, tarpaulin rack, etc.

There is also a suspended rear axle, which is called the last bridge that can be hoisted when not in use.

At present, the most commonly used method is to use high-strength (domestic advanced) steel to reduce self-weight. High-strength steel semi-trailer is lighter than ordinary carbon steel light semi-trailer. Using high-strength steel imported from Sweden to optimize the design of semi-trailer can reduce the self-weight of semi-trailer by more than 1.3 tons without changing the carrying capacity of semi-trailer, and effectively improve the vehicle efficiency.

Advantages and characteristics of ultra-light semi-trailer

Compared with "integral" cars, semi-trailers can improve the comprehensive economic benefits of road transportation. The transportation efficiency can be improved by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced by 20-30%. More importantly, the use of ultra-light semi-trailer can also promote the organizational form of logistics in China to a certain extent! It has provided better help for the sustainable development of the economy.

Especially now, ZF has adjusted the transportation industry. The total weight of vehicles and goods driven by two wheels shall not exceed 55 tons, and the goods driven by one wheel shall not exceed 5 1 ton.
