by Event review recently, Taicang, Jiangsu, near National Highway 346 and Liuxiang highway.
A semi-trailer truck loaded with goods suddenly rolled over when turning, and the loaded cement facilities pressed hard against the car on the side.
A number of passengers came out of the smashed car.
In the accident, the front parts of the two cars were seriously damaged.
Fortunately, no passengers in the car were injured.
It is not difficult to see in the video that a concrete precast component transport vehicle overturned.
If the precast concrete components are damaged in storage, transportation, hoisting and other links, it will be difficult to repair, which will not only delay the construction period, but also cause economic losses.
Therefore, the storage tools and logistics organization of large precast concrete components are very important.
For the safe transportation of precast concrete components, we interviewed Hunan Sany kuaerju Housing Industry Co., Ltd.
and Nanjing Renchuang Mold Technology Co., Ltd.
to listen to what they said.
How to transport precast concrete components safely and efficiently? Prefabricated building network: what is the development status of logistics and transportation of prefabricated components in China? What are the main modes of transportation? Compared with foreign countries, what is the difference? In recent years, with the gradual increase of national support for prefabricated buildings, the prefabricated parts market shows 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, belonging to the category of heavy transportation.
At present, semi-trailer is the main means of heavy transportation in the transportation market.
Semi-trailer is also favored by customers because of mature technology and strong cargo carrying capacity.
There is a large market stock.
Therefore, most prefabricated parts in China are still transported by semi-trailer.
The specific method is to install transportation tooling on the semi-trailer loading platform, including vertical tooling and inclined tooling, and the prefabricated parts are placed on the tooling and bound and fixed with ropes.
This transportation mode has high center of gravity and poor driving stability, which is easy to cause safety accidents, and the vehicles need to wait in place during loading and unloading, which is inefficient.
In foreign countries, such as Europe, America, Japan and other countries with relatively mature precast parts market, precast 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 adopts hollow body, semi-axle suspension and special fixture for the fixation of prefabricated parts.
During loading and unloading, it does not need the assistance of hoisting equipment.
A single person can complete the operation within 10 minutes, which is very efficient, and when driving normally, The loading plane is only about 0.4m from the ground (the common semi-trailer is basically more than 1m), which greatly reduces the center of gravity of the loaded vehicle and improves the driving stability.
The strong compartment structure on both sides of the vehicle body is not only used to carry all the load, but also can be used as a reliable protective device, which can effectively prevent additional accidents and losses even if the components fall during transportation.
(for details, see the special transport vehicles for prefabricated parts in foreign countries, enough at a 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 assembled housing in China is still relatively not so popular.
It mainly adopts rail flat car transportation and flat trailer transportation.
Compared with foreign professional transport vehicles The domestic vehicles are relatively simple.
Prefabricated building network: how to transport prefabricated components safely? How do you think to prevent such safety accidents from happening again? Sany live fast: at present, the key factor for the 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.
Tooling and rope are generally used for fixing, but there is no unified standard for the design and binding of tooling, and human factors have a great impact on transportation safety.
In addition, overload is also a great threat to transportation safety, and overload is common.
Foreign mature transportation experience is in sharp contrast to domestic inefficient and dangerous transportation modes.
Therefore, to completely solve the safety problem of prefabricated parts transportation, firstly, the specialization of transportation means is the only way and inevitable trend; Secondly, the state should give support at the policy level and vigorously promote the special means of transportation for prefabricated parts.
Sany express started the research and development of special transportation equipment for prefabricated parts as early as 2014, aiming to provide professional transportation tools, improve transportation efficiency and reduce customer equipment investment.
So far, the products have been highly praised by customers.
Nanjing Renchuang: how to transport components safely? We believe that first, overload transportation is not allowed; Second, the steel wire rope should be fixed tightly; Third, the wooden side of the shelf shall 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 live fast: at present, many customers run away from the price of professional preform transport vehicles because the price of special preform transport vehicles is several times that of ordinary flat cars.
Due to the immediate temporary investment, they put safety aside from the first place, but ignore the economic value generated by its efficiency and safety.
It is estimated that the use cost of the special preform transport vehicle is much lower than that of the ordinary semi-trailer, and its income is much higher than that of the ordinary semi-trailer.
(with 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.
