What is the length of ultra-low flat semi-trailer?

Low plate semi-trailer is specially used for the transport of heavy vehicles, rail vehicles, mining machinery, forestry machinery, construction machinery and other non-removable large goods vehicles, commonly known as "big plate" in the industry, the structure is trailer axle generally concave beam type, the front section is gooseneck, the middle section is the cargo platform, the rear section is the wheel frame, and there is no fence around.

Compared with the ordinary semi-trailer, the center of gravity height of the low plate semi-trailer is lower, on the one hand, it can facilitate the loading and unloading of goods, on the other hand, it can reduce the height of the vehicle as much as possible, improve the smoothness of transportation and the passing of the vehicle on the height limit.

In fact, in addition to the low plate, there is also an ultra-low plate, as the name suggests, the height of the platform of this vehicle is shorter than that of the ordinary low plate, almost to the extent of sticking to the ground, in the words of netizens: with a speed bump can be used to waste, if you encounter the sedimentation section, is not it directly with the chassis friction road?

Such a model is relatively rare in the country, which is also determined by the complex transportation road conditions in the country, but in some very special conditions, such as the transportation of some ultra-high and ultra-large construction industrial equipment, ultra-low plate will come in handy.

This type of trailer in Europe is known as "multi-axle low flat trailer", generally by a fixed or removable front neck, middle splint and rear axle composition, the biggest feature is that the distance between the cargo platform and the road is very short, so can achieve the maximum effective loading height.

At the same time, the cargo platform of this type of model has been "double drop" height design, that is, the height of the goose neck and the rear end tire has been lowered, which can further reduce the height of the cargo platform, so that the center of trailer axle gravity of the goods is lower, and the transportation is safer, suitable for all kinds of heavy, ultra-long and oversized goods.

In addition, the number of axles, load factor, body size and even composition of this type of vehicle can be deeply customized according to the actual transportation needs.

The common ultra-low flat semi-trailer can be mainly divided into three categories:

1. Fixed gooseneck type

As the name suggests, refers to the goose neck fixed design of ultra-low flat transport vehicle, is also relatively common in China, the structure is simple, light weight, the tail with more lifting ramps, loading and unloading of goods is more convenient, some large excavators, bulldozers, mining equipment, etc., generally choose this model for transportation.

2. Detachable Gooseneck

This model is characterized by the gooseneck structure with mechanical locking function, which can achieve the removal of gooseneck, some models of the cargo platform also with hydraulic lifting function, after the tractor towed the gooseneck from the trailer, the heavy equipment with its own power can move directly from the front of the cargo platform to the delivery platform, to achieve rapid loading and unloading. There are some models trailer axle do not have hydraulic lifting platform, but the front ladder is designed, which can form a small Angle ramp with the road surface, and can also achieve the same loading and unloading function.

3, the cargo platform can be retractable

This type of model is characterized by the "#" structure of the cargo platform part can be realized, and it is more suitable for the transportation of ultra-long goods.
