At 5:14 a.m. today (August 9),

"The first ring in the world"

Officially delivered from Jinan,

"Over mountains and mountains",

It is expected to arrive at Weifang port wharf of Shandong port at 5 pm.

How to transport this big guy has always been a topic of most concern to netizens.

The "world No. 1 ring" belongs to the "non detachable" special large parts, which need to be transported by special vehicles for special large parts.

There are 106 wheels of special vehicles for transporting the "world's first ring", including 10 wheels of tractor and 96 wheels of flat car behind. The flat car can control the steering angle of different wheels and the overall height of the flat car through a separate control system. The "world first ring" shall be reinforced with special tooling before transportation, which is more than 3 meters above the ground. During transportation, it needs to occupy 4 lanes of the expressway.

In order to ensure the safety of passing through the north line of Jiqing during the transportation of the "world's first ring", and make every effort to prevent road traffic accidents and long-term and long-distance traffic congestion, the traffic police corps of Shandong Provincial Public Security Department has also taken temporary traffic control measures for the north line of Jiqing.

Since all kinds of traffic signs and traffic facilities on the road are made in accordance with national standards, it can be just higher than most of the traffic signs on the guardrail and lower than all kinds of hanging road signs and cameras, so it does not need to dismantle a large number of traffic facilities.

Some netizens wondered how such large goods passed through the toll station? Is it necessary to demolish the toll booths?

The answer is: No. Because an entrance is specially opened at one place of the guardrail, there is no need to enter the toll station, and the roadblocks along the way have also been partially removed.

After the traffic police and the expressway strictly confirm the safety, they drive into the expressway, and then they are escorted by the Shandong traffic police and drive all the way to Weifang. When driving out of the expressway, a general method is adopted to drive out from the side of the guardrail, without removing the toll gate.

In the previous article, we introduced that the special large cargo transport vehicle is a special vehicle for transporting out of gauge and heavy goods. Because of the huge volume, heavy and inseparable cargo, it exceeds the quality of ordinary trucks, and even exceeds the specified limits of highway alignment and bridge and culvert capacity. It needs to bypass, rebuild or even remove the obstacles encountered.

In general, special large transport trailers can be divided into three different overrun levels:

1. Super long and large piece.

The ultra long and large parts are the least difficult to transport among the three out of gauge levels, generally as long as they do not affect the turning of the vehicle. If the ultra long part affects the turning, on the premise of ensuring the rigidity of the goods, the hydraulic support arm can be used to erect or slant it, and with the cooperation of the team, it can pass through most of the bends and reach the destination through reasonable route planning.

2. Super wide large piece.

The transportation difficulty of super wide and large pieces is second. As long as the road width allows, there is basically no problem in driving. The most feared thing is to meet the upper limit wide pole or toll station. In contrast, the width limiting pole may be able to bypass, but there is generally no way to bypass the toll station. Of course, if it is a national emergency project, you may choose to dismantle the toll station or temporarily open a special entrance and exit for traffic.

3. Super high and overweight large parts.

High height and high center of gravity of ultra-high large pieces are one of the most dangerous large pieces of transportation. During transportation, a lot of steel wire ropes and contraction hinges are generally used to stabilize the goods to ensure transportation safety.

Overweight and large pieces are more complicated. The power and torque of trailers are limited. For transportation of several hundred tons, chassis with more powerful power performance is often used, equipped with remote control driving system, and hundreds of tires are used to reduce the pressure of goods on the ground. Generally, the maximum speed of the vehicle will not exceed 10km / h, and the technical condition and wear status of the vehicle must be frequently checked during the transportation.

Vehicles transporting special large pieces are generally three-line six axles, three-line six axles, four line eight axles, five line ten axles, six line twelve axles, etc. and so on. Two axles are installed in a row.

However, special vehicles will also be used in case of extra wide and overweight goods. For example, from the above, we can see that the flatbed truck transporting the "world's first ring" has 8 rows of axles, 96 wheels, and 12 wheels in one row. According to the calculation of 4 wheels per axle, 3 axles are installed in parallel in one row.

In order to ensure safety, in addition to the escort of front and rear police vehicles, police are on duty at all intersections along the road to ensure the safety of the masses. Finally, after arriving at the port, the "world first ring" will be transported to the ferry as a whole, reinforced and finally transported to Dalian for further processing.

The goods carried by special large transport vehicles are special, which requires higher performance of the vehicles. Especially, the chassis and axle directly determine the bearing capacity of the vehicles. It is necessary to select products with reliable quality and strict rigidity strength. Darong group is an enterprise specialized in R & D and production of commercial axles in Liangshan, Shandong Province. It has been deeply engaged in the axle industry for 20 years and is famous for its high cost performance. All the axles produced by Darong have gone through 15 high-precision processes. The comprehensive mechanical properties of the products are excellent, such as strength, toughness and ductility. In addition to the common disc axles, American axles, German axles, concave axles, special axles and three-line six axle axles in the market, the special axles can also be customized according to the actual needs of customers to meet the diversified needs of vehicle owners.
