It is strongly recommended that rear axles of any trailer tractors transporting dangerous goods with a total mass greater than or equal to 12000kg, all semi-trailers for transport of dangerous goods, and three-axle fence trailer and side wall trailers should be equipped with air suspension. With the clear support of the policy in China, what are the advantages of air suspension? Below are some advantages of air suspension for side wall semi-trailers.
Advantages of Air Suspension for 3 Axel 80t Side Wall Trailer
The biggest advantage of air suspension is that it can reduce the impact of carried goods on the trailer body inner surface in bumps in terms of protecting freight Safety. It can also reduce tire wear, reduce fuel consumption, etc.
In China, domestic use of air suspension has accumulated plenty practical experience. With the development of technology, air suspension has become an indispensable standard equipment for heavy trucks and special vehicles.
Absobing Impact from Small Range of Bumps
The adjustment of the air spring can ensure the constant height of the trailer, reduce impact on the trailer side board during bumps, protect the safety of freight, and improve the service life of the trailer.
Using air suspension can effectively reduce tire wear and fuel consumption. According to statistics, under the same road conditions and loading conditions, the fuel consumption per 100 kilometers is reduced by more than 1.2 liters for trailers equipped with air suspension.
Enhance Protection of Accessories
The air suspension system can absorb the vibration caused by the bumpy road more effectively, reduce the distortion and impact of the vehicle during driving, and thus have smaller amojut of impact on axle parts, tires, frames, boxes, etc.
The air suspension transportation is more stable. While equipped with air suspension, the center of gravity of the trailer is almost unchanged when travelling, which means the axial and radial stability are good and it is safer and more reliable. The braking system is adopted to effectively avoid the forward impact of the vehicle during emergency braking.
Policy of Air Suspension on 3 Axel 80t Side Wall Trailer
The new "GB7258" stipulates that the rear axle of a dangerous goods transport truck with a total mass greater than or equal to 12000kg shall be equipped with air suspension for all dangerous goods transport semi-trailers. It is understandable since most of the goods loaded by these trailers are inflammable and explosive liquids or gases. The more stable the trailer travels during transportation, the safer it is for everyone and everything on the road. Compared with the traditional steel plate suspension, the air suspension has better shock absorption effect, which makes truck and trailer with air suspension more stable. Now many cold chain, hazardous chemicals, and glass transport vehicles are already using air suspension. The use of air suspension on dangerous goods transport vehicles is indeed a high priority for safety. The danger in the transportation of dangerous goods is friction and bumps during the transportation of dangerous chemicals. With air suspension, the bumps and friction coefficients of dangerous goods can be reduced. ,safer.
Disadvantages of Air Suspension on 3 Axel 80t Side Wall Trailer
It is not only the standard air suspension for dangerous goods transport vehicles, but the new regulations also stipulate that the three-axle fence type and side wall semi-trailer should be equipped with air suspension. To say that the use of air suspension for dangerous goods transport vehicles is to ensure the stability of the transportation of dangerous goods, then the three-axle fence type and side wall semi-trailer of Lapucar should also be equipped with air suspension as standard, which means one size fits all. At present, domestic retail semi-trailers are mainly fence type and side wall type. The use of air suspension can indeed improve the stability and comfort of the vehicle, but the cost of a trailer equipped with air suspension is much higher than that of ordinary suspension. Taking the BPW axle trailer as an example, depending on the configuration, the air suspension for the three axles is tens of thousands of yuan more expensive than the steel plate suspension. This means the cost of a trailer could be tens of thousands of yuan higher than the steel plate suspension with drum brake version.
