1. What is a lowbed semi-trailer, and how does it differ from a regular semi-trailer?
A lowbed semi-trailer, also often called a low-bed trailer or low-bed truck, is a type of semi-trailer specifically designed for transporting heavy machinery, construction equipment, and extra-high cargo. Its most distinctive feature is its cargo bed (i.e., load surface) that is very low to the ground. Compared to regular semi-trailers, lowbed semi-trailers have a lower center of gravity, making them safer and more stable when transporting extra-high and extra-heavy cargo.

2. What cargo are lowboy semi-trailers primarily used to transport?
Lowbed semi-trailers are primarily used to transport cargo that cannot be transported using regular trucks or containers due to size or weight restrictions. Common cargo types include:
Large construction machinery, such as excavators, bulldozers, loaders, and road rollers.
Agricultural machinery: such as large combine harvesters and seed drills.
Industrial equipment: such as transformers, large boilers, and generator sets.
Special vehicles: such as crawler cranes and large drilling rigs.

3. How do I choose the right lowbed semi-trailer?
When choosing a lowbed semi-trailer, consider the following key factors:
Load Capacity: Choose the appropriate load capacity based on the maximum weight of the cargo you intend to transport.
Dimensions: The length, width, and height of the cargo bed must be able to accommodate your cargo.
Number of Axles: The more axles, the greater the load capacity and the less pressure on the road. Choose a model with two, three, four, or more axles depending on the cargo weight.
Suspension System: Common suspension systems include mechanical and air suspension. Air suspension provides better shock absorption and is more suitable for transporting precision equipment.
Loading and Unloading Method: Consider the ease of loading and unloading cargo. Some lowbed semi-trailers feature a gooseneck design that can be detached from the front, making it easier for equipment to be loaded and unloaded.

4. What technical specifications should I consider when purchasing a lowbed semi-trailer?
In addition to the above factors, you should also pay attention to the following technical specifications:
Main Beam Material: High-quality, high-strength steel (such as Q345B) ensures the strength and durability of the frame. Tire Type and Quantity: Select the appropriate tire size and ply rating, as well as the number of spare tires, based on load requirements.
Braking System: Ensure the braking system is reliable and meets safety standards.
Electrical System: Check that the lighting and wiring meet standards to ensure safe nighttime driving.
Optional Features: Choose hydraulic ladders, retractable features, side guardrails, and other features as needed.

5. Are there any special requirements for operating a lowbed semi-trailer?
Operating a lowbed semi-trailer requires an A2 or higher driver’s license. Due to the vehicle’s large length, width, height, and weight, drivers must be experienced and exercise extreme caution when turning, reversing, and maneuvering in narrow roads. Furthermore, transporting oversized cargo may require an overweight transport permit.
