The technical specifications of container transport trailers center primarily on load-bearing capacity; the rated gross weight generally ranges from 30 to 80 tons, depending on the number of axles and the structural design. Common three-axle skeletal trailers typically have a rated load capacity of 30 to 45 tons, whereas four-axle or reinforced models can exceed 60 tons, making them suitable for heavy-duty or long-haul transport.
Regarding dimensions, these trailers are usually around 12 meters long and 2.5 meters wide, complying with international road transport standards. The container locking mechanisms on the chassis are arranged according to standardized layouts, accommodating 20-foot, 40-foot, and some 45-foot containers. Wheelbase and track width are optimized based on load requirements to ensure vehicle stability during high-speed travel and cornering.
Specifications for powertrain and braking systems are also critical components. Braking systems typically utilize a dual-circuit pneumatic setup with an operating pressure range of approximately 0.6 to 0.8 MPa, ensuring reliable braking response under various operating conditions. Suspension systems fall into two categories-leaf spring and air suspension-with air suspension generally offering superior shock absorption and height adjustment capabilities. Additionally, tire specifications commonly include 11.00R20 or 12R22.5 sizes to meet the demands of heavy loads and long-distance operations.
