In Europe, special goods such as prefabricated parts and glass are transported by special trailers.
However, in China, the transportation vehicles of these goods are no different from ordinary goods.
A 17 meter 5 low flat plate or 13 meter column plate car can be transported with an A-frame.
However, with the transformation of the domestic logistics market, the degree of trailer specialization is bound to be higher and higher.
In view of this trend, Sany Heavy Industry first launched the first special semi-trailer for prefabricated parts in China.
It is estimated that many friends have never seen such a trailer.
Let’s have a look.
As early as last autumn, this model sy9400tyc prefabricated semi-trailer has been released and appeared in the 13th China International Housing Industry Expo.
It is announced that Sany group will fully enter the PC (precast concrete) industry in the construction field.
The biggest feature of this prefabricated semi-trailer is that all three axles are in the form of independent suspension.
In order to ship the whole prefabricated parts, the trailer adopts the form of independent suspension, which effectively reduces the body height.
The interior of the trailer adopts the design form of cavity.
There are slide rail shaped brackets on both sides above the bottom frame, which are used to carry special prefabricated parts brackets.
The axle suspension adopts hydro pneumatic suspension (that is, our Changshu hydraulic suspension), which reduces the bounce during driving and avoids the damage of goods during transportation.
The size of the loading space is 9.5mx 3.75m high x 1.5m wide.
The design allows a total weight of 40t, a rated load of 29.5t and a curb weight of 10.5t.
Sy9400tyc semi-trailer adopts 385 / 65r22 520pr wide base single tire.
The advantage of using this size of tire is to reduce the dead weight and control the body size (if the form of combined double tire is adopted, the width will increase and the cargo space will be reduced).
The goods are loaded in the form of special pallets for prefabricated parts, and the loading and unloading of pallets is realized with the help of hydraulic lifting device, which is convenient for unloading and improves the efficiency of transportation.
It is worth noting that the traction pin of such prefabricated semi-trailer is relatively high.
In order to match the trailer, the manufacturer specially adopts the hydraulic rod to reduce the height of the traction pin, so as to achieve the best transportation height.
Although such a special semi-trailer for prefabricated parts is very attractive, the high price is still an obstacle to its popularization.
It is understood that the price of this Sany Heavy Industry precast slab semi-trailer is more than 700000.
It seems that it will be a non mainstream Trailer product for a long time, but with the development of the domestic market, such specialized semi-trailer is bound to be more and more.
