Long head Semi trailer development opportunity Coming?

When it comes to long-headed semitrailers, many people first think of Western models, such as the well-known Optimus Prime Peterbilt 389, a typical long-headed semitrailer. In contrast, the market share of the long head semi trailer is relatively small, mainly the flat head semi trailer.

One of the most important reasons is the legal limit on the length of semi-trailers. In the past, regulations required the total length of the semi-trailer to be no more than 17 meters, of which the carriage accounted for 13 meters, leaving a maximum of 4 meters for the tractor, so the engine had to be moved under the cab.

However, with the introduction and implementation of the new national standard GB1589, the length limit of long-head hinged train is relaxed to 18.1 meters, 1 meter more than the original, which to a certain extent gives more space to the tractor of long-head semi-trailer, owners can use long-head semi-trailer to transport goods on the basis of not losing the length of the carriage.

Despite the "green pass", is a long-headed semi worth pursuing? This also starts from the advantages and disadvantages of the long head semi trailer itself.

Main advantages of long head semi trailer:

1, better safety performance: compared with the flat head semi-trailer, long head semi-trailer in front of the design of a "long nose", so more than 2 meters of buffer zone, if there is an accident, the cockpit is not easy to deformation, not easy to rollover, to protect the safety of the driver. This is one of the reasons why Chinese and foreign school buses all choose "long nose" models.

2. Better driving comfort: because the vehicle engine is changed from below the cockpit to the front of the cockpit, when the vehicle is running, the indoor noise is smaller, the vibration is smaller, and the driving comfort is stronger.

3, more fuel saving: the head design of the long head semi trailer is special, when driving can reduce air resistance, to a certain extent than the flat head semi trailer more fuel saving, especially in the current background of rising fuel prices, can help the owner to save a lot of money.

4, more convenient maintenance: long head semi trailer is more convenient to use maintenance, maintenance can open the hood, compared to the flat head semi trailer maintenance needs to flip the cab, much more convenient.

Every upside has its downside, and the long-headed semi is no exception. Next, let's talk about the disadvantages of the long-headed semi-trailer:

1. Poor driving vision: the driving vision of long head semi-trailer is not as good as that of flat head semi-trailer, especially for owners who have been used to flat head semi-trailer, if they change the model, they need an adaptation period.

2. Turning and turning is not flexible: the long head semi-trailer is more flexible because of the longer traction front, so the turning radius is larger, so when turning or turning, it is not as flexible as the flat head semi-trailer, and there is a higher driving difficulty. Especially in our country, the traffic condition is relatively crowded, like in southwest area, the road is relatively narrow, which is not suitable for the use of the long-head semi trailer. This is also the reason for the large share of flat head semi-trailers in China and European countries.

3. Higher body weight: the length of the tractor of the long-head semi-trailer is longer, so its own weight is heavier, which is also a fact. Under the premise of the total weight limit of the transport vehicle, it is also not a small constraint.

4. Higher price: In terms of manufacturing cost, the price of long-head semi-trailer is higher than that of flat-head semi-trailer, and the change of model means more input cost.

To sum up, although GB1589 has relaxed the length of long-head hinged trains, the development prospects of long-head cars still need to be analyzed and understood objectively and comprehensively. In the state of road transport in China, flat-head cars are more suitable for the basic situation in China, and the development of long-head cars still has a long way to go.

No matter what kind of semi-trailer the owner chooses, it is necessary to pay attention to the selection and screening of the trailer axle. DARO Group is one of the earliest trailer axle enterprises in China, and also one of the earliest mass production enterprises of all-in-one trailer axle in Liangshan special vehicle production base. With reliable quality and real price, it helps car owners to save energy and increase efficiency.
