Advantages:

• Good shock absorption effect: It can effectively absorb the vibration and impact of the road, provide excellent driving stability and comfort for trailers and trucks, and greatly reduce the risk of damage to goods during transportation.
• Height adjustability: The height of the vehicle body can be flexibly adjusted according to different road conditions and cargo conditions, such as raising the vehicle body when passing through rugged roads, and lowering the vehicle body to improve stability when driving at high speeds.
• Strong adaptability to the road surface: It can better adapt to various complex road conditions, such as raising the vehicle body when empty or with less cargo, saving fuel consumption and damage to the trailer.

Disadvantages:

• High cost: Compared with mechanical suspension, the initial installation and maintenance costs of air suspension are relatively expensive.
• Complex system: Once a fault occurs, it is difficult to repair. Application scenario: Air suspension is often used in occasions with high requirements for transportation quality, such as transporting precision instruments, fragile items, etc., and is also common in the field of high-end logistics and transportation.

Whether it is air suspension or mechanical suspension, they play an indispensable role in the operation of semi-trailers. When choosing, users need to consider a variety of factors, such as transportation needs, budget, and road conditions. If you focus on high quality and comfort in transportation and have sufficient budget, air suspension may be a better choice; if you value cost and simplicity and reliability, mechanical suspension can meet basic requirements. Of course, many customers will also choose a combination of air suspension and mechanical suspension. For example, for a 4-axles flatbed trailer, the first axle is air suspension, and the rest are mechanical suspension. This can not only effectively reduce shock, but also be able to calmly deal with heavy cargo transportation.
