Side curtain trailers are the main logistics transportation tools in many European countries. Especially in the past 20 years, they have developed rapidly. The vehicle product technology and accessory technology are very mature.

Curtain side trailers have been introduced to China for more than ten years, but they have not been developed. There are standard problems. There are logistics companies’ understanding of the product performance and product application. There are also government regulatory agencies that do not have a deep understanding of the safety performance of the model.

▎Similar to the development in China, European trailers have long been mainly hung on flatbed trailers and side wall trailers

In 1920, a German company invented the side wall trailer, and in the 1930s and 1940s, it was mainly flatbed and pallet truck.

In the 1930s, the full trailer was also the main model of European transport.

Wait until the last century 50s and 60s,side wall trailer and the warehouse trailer has been popular application.

When transporting goods, canvas is used to cover the goods, and ropes are used to fix the canvas around, which is basically the same as when we use the warehouse trailer to transport ordinary goods.

In the 1970s and 1980s, the most popular logistics vehicles in continental Europe were still pallet trailers with canvas covered to transport goods, or warehouse trailers with canvas to transport goods.

It is only at this stage that the lightweight design of the trailer has been opened, and the application of aluminum alloy fences has begun.

In 1969, a German company Edscha invented the sliding roof technology. After nearly 10 years of research by Schmitz, a European trailer manufacturer, it finally developed a side curtain semi-trailer with a sliding roof in 1980-1990.

This trailer has a sliding column on the side, between the three sliding columns, and between the sliding column and the front and rear walls, there are wooden cargo crossbars, and the side curtains can slide back and forth.

When loading, the side curtains can be opened and slid to the front or rear of the semi trailer, the cargo barrier can be removed, and the sliding column can also be slid to the front or rear of the semi-trailer to facilitate side loading and unloading.

▎ The development of trailers in Europe is closely related to the logistics industry

From the development history of European trailers, it can be seen that European trailers have developed from flatbed type trailers and pallet trailers to pallet and warehouse grid trailers, and then to side curtain semi-trailers.

The evolution of European trailer products is directly related to the requirements of logistics industry development on loading and unloading efficiency, quality and fixation of goods.

It is easier and safer to use canvas to cover and fix the fence trailer than to use a flatbed trailer. The warehouse-grid type trailer has a higher height and a larger volume, and it is more convenient to fix the goods. It is easier and safer to use the canvas to cover the rain Better performance.

The side curtain trailer has better performance. The sliding roof can be opened for loading, and heavy goods such as steel coils can be hoisted into the side curtain vehicle by a crane and then fixed.

The two sides of the side curtain trailer can load and unload goods at the same time, and the loading and unloading efficiency is much higher than that of the fence or side wall trailer.

Therefore, the side curtain trailer is the upgrading model of the pallet trailer and the warehouse grid trailer, and it is the product of the technological progress of the trailer products and the modernization of logistics equipment.
