by Event review Recently, Taicang, Jiangsu Province, near the 346 National Highway and Liuxiang Highway.
A semi-trailer truck loaded with goods suddenly rolled over when turning, and the loaded cement facilities pressed the car on the side.
Many passengers came out of the smashed car.
In the accident, the front part of the two cars was seriously damaged.
Fortunately, no passengers in the car were injured.
It is not difficult to see in the video that a concrete prefabricated component transport vehicle overturned.
If precast concrete components are damaged in storage, transportation, hoisting and other links, it will be difficult to repair, which will delay the construction period and cause economic losses.
Therefore, the storage tools and logistics organization of large prefabricated concrete components are very important.
With regard to the safe transportation of prefabricated concrete components, we interviewed Hunan Sany Kuai’erju Housing Industry Co., Ltd.
and Nanjing Renchuang Mold Technology Co., Ltd.
to hear what they said.
How to transport precast concrete components safely and efficiently? Prefabricated building network: How is the logistics and transportation development of prefabricated components in China? What are the main modes of transportation? Compared with foreign countries, what is the difference? Sany is fast and fast: in recent years, with the gradual increase of the state’s support for prefabricated buildings, the prefabricated parts market has shown an explosive growth trend, the total production of prefabricated parts is increasing, and the demand for transportation is also increasing.
Prefabricated parts are generally large in size and weight, and belong to the category of heavy transportation.
At present, the heavy transportation vehicles in the transportation market are mainly semi-trailers.
Semi-trailers are also favored by customers because of their mature technology and strong cargo carrying capacity.
The market holds a large number.
Therefore, most of the prefabricated parts in the country are still transported by semi-trailers.
The specific method is to add transportation tooling on the semi-trailer loading platform, including vertical and inclined tooling, prefabricated parts placed on the tooling, and fixed with ropes.
This mode of transportation has a high center of gravity of the whole vehicle, poor driving stability, and is easy to cause safety accidents.
In addition, during loading and unloading, the vehicles need to wait in place, which is inefficient.
In foreign countries, such as Europe, America and Japan, where the prefabricated parts market is relatively mature, the prefabricated parts are transported by special transport vehicles, which have been used for more than 30 years.
Compared with the ordinary semi-trailer, the special transport vehicle has the function of self-loading and unloading.
It uses hollow body, semi-axle suspension, and special fixture to fix the prefabricated parts.
During loading and unloading, without the assistance of lifting equipment, a single person can complete the operation within 10 minutes, with high efficiency.
In normal driving, the loading plane is only about 0.4 meters from the ground (the ordinary semi-trailer is basically more than 1 meter), which greatly reduces the center of gravity of the whole vehicle after loading, and has higher driving stability.
The strong car body structure on both sides of the car body is not only used to bear all the loads, but also can be used as a reliable protective device.
Even if the component topples during transportation, it can effectively prevent additional accidents and losses.
(For details, see the special transport vehicles for prefabricated parts on the top of foreign countries.
You can see it at one time!) Nanjing Renchuang: The development of logistics and transportation of prefabricated components in China is still relatively backward compared with that in foreign countries.
At present, the development of prefabricated housing in China is still relatively not so popular.
Rail flat car transportation and flat trailer transportation are mainly used.
Compared with foreign professional transport vehicles, domestic vehicles are relatively simple.
Prefabricated building network: how to transport prefabricated components safely? How do you think to avoid the recurrence of such safety accidents? Sany is fast and fast: At present, the key factor of frequent transportation accidents of prefabricated parts in China is the high center of gravity and unreliable fixation.
The high center of gravity is determined by the ordinary semi-trailer itself and cannot be changed.
Fixing generally adopts tooling and rope coordination, but there is no uniform standard for the design and binding of tooling, and human factors have a great impact on transportation safety.
In addition, overloading is also a great threat to transportation safety, and overloading is widespread.
The mature foreign transportation experience is in sharp contrast with the inefficient and dangerous domestic transportation modes.
Therefore, to thoroughly solve the safety problem of prefabricated parts transportation, first of all, the specialization of transportation means is the only way and the inevitable trend; Secondly, the state should give support at the policy level and vigorously promote the special transportation tools for prefabricated parts.
As early as 2014, Sany Kuaiju started the research and development of special transportation equipment for prefabricated parts, aiming to provide professional transportation tools, improve transportation efficiency and reduce customer equipment investment.
The product has been highly praised by customers since it was launched into the market.
Nanjing Renchuang: How to transport components safely? We believe that first, overload transportation is not allowed; Second, the wire rope should be fixed tightly; The third is that the wooden shelf should be placed on the vehicle and checked; Fourth, drivers should maintain good driving habits.
What is the transportation cost of using professional prefabricated component transport vehicles? Sany is fast and fast: now, many customers run away from the price of professional prefabricated transport vehicles because the price of special prefabricated transport vehicles is several times of that of ordinary flatbed vehicles.
Due to the temporary investment at present, safety is put aside from the first place, but the economic value generated by its efficiency and safety is ignored.
It is estimated that the use cost of the special prefabricated unit transport vehicle is far lower than that of the ordinary semi-trailer, and the income it brings is also far higher than that of the ordinary semi-trailer.
(Attach economic benefit analysis) Nanjing Renchuang: compared with ordinary logistics vehicles, the cost of using professional prefabricated component transport vehicles is lower, the loading rate is higher, and the utilization rate is more reasonable.
