What is the special large transport trailer?

Trailer is the backbone of the current logistics transportation industry, special large transport trailer refers to the special transport of over limit, heavy goods trailer. Due to its huge volume of cargo, heavy and indivisible, so the quality of more than the ordinary truck, even more than the highway alignment and bridge culverts through the capacity of the prescribed limits, need to detoured, reconstruction or even removal of obstacles encountered.

In general, special bulky transport trailers can be mainly divided into three different over-limit levels:

1. Super long and large pieces.

Super long and large pieces are the relatively smallest of the three over the limit levels of transportation difficulty, generally as long as it does not affect the vehicle can turn. If the extra long part affects the turning, on the premise of ensuring the stiffness of the cargo, it can be raised or slanted with a hydraulic support arm. Together with the cooperation of the team, it can go through most of the turns and reach the destination through reasonable route planning.

2, super wide parts.

Super generous transportation difficulty, as long as the road width allows, driving basic no problem, the most afraid is to meet the upper limit of the wide pole or toll station. In contrast, the limit bar may still be able to bypass, but the toll booth is generally no way to bypass. Of course, if it is a national emergency project, it may choose to remove the toll station.

3. Super large and overweight large pieces.

High height, high center of gravity, is one of the highest risk of large transport work, in the transport will generally use a lot of steel wire rope and shrinkage hinges to stabilize the goods to ensure transportation safety.

The heavy parts are more complex, the trailer power and torque is limited, this hundreds of tons of transportation, often use more powerful chassis, equipped with remote control driving system, and then through hundreds of tires to slow the pressure of the goods on the ground, the highest speed will not exceed 10km/h, but also frequent inspection of the technical condition and wear state of the vehicle. Sometimes it takes several months or even half a year to transport a large piece of heavy weight, which shows the difficulty.

So, what are the common special large transport trailers?

1. Classification by trailer length:

It can be divided into 9.5 meters, 13 meters, 15 meters, 16 meters, 16.5 meters, 17.5 meters, 18 meters, 20 meters and 22 meters.

2. Classification by trailer type:

Mainly can be divided into flat car, ladder car, groove car.

3. Classification by trailer axle:

It can be divided into three lines three axes, three lines six axes, four lines eight axes, five lines ten axes, six lines twelve axes.

Because the cargo carried by the special large transport trailer is special, the performance requirements of the vehicle are higher, especially the chassis axle, which directly determines the bearing capacity of the trailer. It is necessary to choose the products with reliable quality and strict standards of stiffness and strength. DARO Group is a company specializing in the development and production of trailer axles in Liangshan, Shandong Province. It has been deeply engaged in the axle industry for 20 years and is known for its high cost performance. All the trailer axles produced by DARO go through 15 high precision processes, and the comprehensive mechanical properties of the products are excellent, such as strength, toughness, ductility, etc., which can be customized according to the actual needs of customers to meet the diversified needs of owners.
