How To Choose A Suitable Semi-trailer

1. Clarify the transportation needs

Cargo type

Different cargoes have different requirements for semi-trailers. For example, transporting heavy machinery and equipment may require a low-bed semi-trailer to ensure the stability and safety of the cargo; transporting bulk cargo may require a dump semi-trailer for easy unloading. For fragile cargo, it is necessary to choose a semi-trailer with good shock absorption performance to reduce damage to the cargo during transportation.

Transportation distance

Long-distance transportation requires consideration of the comfort and fuel economy of the semi-trailer. Choosing a semi-trailer with a good suspension system and low wind resistance design can reduce fuel consumption and improve transportation efficiency. Short-distance transportation can pay more attention to the flexibility and maneuverability of the semi-trailer so that it can travel on urban roads and narrow areas.

Transportation frequency

High-frequency transportation requires the selection of durable and reliable semi-trailers to reduce the time and cost of repairs and maintenance. Low-frequency transportation can consider leasing semi-trailers to reduce the initial investment cost.

2. Consider the performance parameters of the semi-trailer

Load capacity

Choose a suitable load capacity according to transportation needs. Too large a load capacity may cause overloading and affect transportation safety; too small a load capacity may not meet transportation needs and increase transportation costs.

Pay attention to the total mass and axle load distribution of the semi-trailer to ensure that it meets the requirements of road transport regulations.

Size

The size of the semi-trailer should be selected according to the size of the transported goods and the restrictions of the transport route. Semi-trailers that are too long or too wide may have difficulty driving on narrow roads and bridges, increasing transportation risks.

At the same time, the height of the semi-trailer should be considered to ensure that it can pass through height-restricted areas such as tunnels and overpasses.

Suspension system

A good suspension system can provide smooth driving performance and reduce vibration and damage to goods during transportation. Common suspension systems include leaf spring suspension and air suspension. Air suspension has better shock absorption performance and adjustability, but the price is relatively high.

Braking system

A reliable braking system is the key to ensuring transportation safety. Choose a semi-trailer with a high-performance braking system, such as disc brakes or drum brakes, and ensure that the brake system is easy to maintain and maintain.

Tires

Choose tires suitable for different road conditions and transportation needs. For example, for long-distance transportation, wear-resistant and low rolling resistance tires can be selected to reduce fuel consumption; for short-distance transportation, tires with strong grip can be selected to improve driving safety.
