by Event review: Recently, in Taicang, Jiangsu, near the 346 National Highway and Liuxiang Highway.
A semi trailer truck loaded with goods suddenly rolled over while turning, and the loaded cement facilities fiercely pressed against the sedan on the side.
Multiple passengers emerged from the smashed car one after another.
In the accident, the front parts of the two sedans were severely damaged, but fortunately no passengers were injured inside.
It is not difficult to see in the video that a concrete prefabricated component transport vehicle overturned.
If prefabricated concrete components are damaged during storage, transportation, lifting, and other processes, it will be difficult to repair, which not only delays the construction period but also causes economic losses.
Therefore, the storage tools and logistics organization of large prefabricated concrete components are very important.
We interviewed Hunan Sany Kuai’eju Residential Industry Co., Ltd.
and Nanjing Renchuang Mold Technology Co., Ltd.
regarding the safety transportation of prefabricated concrete components to hear their opinions.
How to safely and efficiently transport prefabricated concrete components? Prefabricated Building Network: What is the development status of logistics and transportation for prefabricated components in China? What are the main transportation methods used? What is the difference compared to foreign countries? Sany: In recent years, with the gradual increase of national support for prefabricated building, 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 components are generally large in size and weight, and belong to the category of heavy transportation.
Currently, semi trailers are the main means of heavy transportation in the transportation market.
Semi trailers are also favored by customers due to their mature technology and strong cargo carrying capacity, and have a large market share.
Therefore, the vast majority of prefabricated components in China still use semi trailers for transportation.
The specific method is to install transportation fixtures on the semi trailer loading platform, including vertical and inclined fixtures, prefabricated parts placed on the fixtures, and fixed with ropes.
This transportation method has a high center of gravity of the entire vehicle, poor driving stability, and is prone to safety accidents.
Moreover, during loading and unloading, 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, dedicated transport vehicles are used for the transportation of prefabricated parts, with a usage history of over 30 years.
Compared to ordinary semi trailers, specialized transport vehicles have self loading and unloading functions, using hollow body, semi axle suspension, and specialized fixtures for fixing prefabricated parts.
During loading and unloading, there is no need for lifting equipment to assist, and a single person can complete the operation within 10 minutes.
The efficiency is extremely high, and during normal driving, the loading plane is only about 0.4 meters from the ground (ordinary semi trailers are generally more than 1 meter), greatly reducing the center of gravity of the entire vehicle after loading, and driving stability is higher
