Introduction of 40ft Side Curtain Semi Trailer
Side curtain trailer is the main logistics and transportation tool in many countries. Especially in the past 20 years, the development speed of the vehicle product and accessories technology has been very fast and has become very mature.
40ft side curtain semi trailers have been introduced to China for more than a decade, but have not been too popular. It’s mainly due to misunderstanding of the product performance and application from logistics companies as well as concerns about their safety from government regulatory departments.
Development and Evolvement of 40ft Side Curtain Semi Trailer
Similar to the development of semi trailers in China, flatbed trailers and side wall trailers used to be the most used types of trailers in Europe.
In 1920, a German company invented the side wall trailer. In the 1930s and 1940s, it was mainly flatbed trailers and side wall trailers.
In 1930s, full-trailers were also the main model in transportation in Europe.
During 1950s and 1960s, side wall trailers and fence trailers had become widely used.
The use of canvas to cover the goods when transporting goods and ropes around the canvas for fixation is basically the same as how we now use fence trailers to transport ordinary goods.
By the 1970s and 1980s, the most popular logistics vehicles in continental Europe were still the side wall trailers covered with canvas to transport goods as well as fence trailers transporting goods in a similar fashion.
This is the stage that lightweight design of semi trailers started, while the application of aluminum alloy side wall trailerszhege.
In 1969, a German company Edrichsha invented sliding top technology. After nearly 10 years of research by the European trailer factory Schmitz, the first 40ft side curtain semi trailer with a sliding roof was finally developed between 1980 and 1990.
Structure of 40ft Side Curtain Semi Trailer
The trailer has sliding columns on the sides, wooden retaining crossbars between the three sliding columns and the front and rear walls. The side cords can slide forward and backward.
When loading, the side cord can be opened and slid to the front or rear of the semi-trailer. The retaining railing can be removed. The sliding column can also be slid to the front or rear of the semi-trailer for side loading and unloading.
The development of trailers is closely related to the development of the logistics industry. It can be seen from the history of the development of European trailers that European trailers are developed from flatbed trailers and side wall trailers to fence trailers, and then to 40ft side curtain semi trailers.
This evolution of European trailer products is directly related to the development of the logistics industry on loading and unloading efficiency requirements, cargo quality requirements and cargo fixation requirements.
Advantanges of 40ft Side Curtain Semi Trailer
It is easier and safer to cover and secure the 40ft side curtain semi trailer with canvas after loading than to use a flatbed trailer. The container plate of the fence trailer is higher to allow higher dimension goods so the volume is larger, more convenient to fasten goods, and provides better water resistance with the canvas as rain cover.
The performance of the side curtain trailer is even better. The sliding roof can be opened for loading. Heavy goods such as steel coils can be lifted into the side curtain car by the crane, and then secured.
Both sides of the 40ft side curtain semi trailer can be loaded and unloaded at the same time, and the loading and unloading efficiency is much higher than that of the side wall or fence trailer.
Therefore, the side curtain trailer is an upgraded model of the side wall and the fence trailer. It is the product of the technological progress of the trailer product and the modernization of logistics equipment.
