Gooseneck Plate Semi-trailer

Flatbed semi-trailer transport truck

The Gooseneck Disc Brake Semi-trailer is a heavy-duty transportation equipment specially designed for efficient and safe cargo transportation. Leveraging its core configurations of the unique "gooseneck-type connection structure" and "disc brake system", it balances the stability of traction transmission and braking safety. It is suitable for scenarios such as long-haul trunk line transportation, heavy equipment transfer, and transportation of bulk goods like building materials and coal. The product offers multiple options for core specifications including size, load capacity, and axles, which can flexibly meet the cargo transportation needs of different industries. Meanwhile, it is equipped with well-known brand kingpins, landing gears, and high-quality suspensions, ensuring durability and operational convenience. It is an optimal choice for modern freight enterprises to improve transportation efficiency.

II. Product Details

1. Gooseneck Disc Brake Semi-trailer: Size Specifications Adapt to Diverse Cargo Scenarios

In terms of size design, this model focuses on the combination of "versatility and specificity". For length, two conventional options (13,500 mm and 14,000 mm) are available to meet the transportation needs of most standard goods. For extra-long equipment (such as construction machinery and large pipes), a detachable gooseneck low-bed version can also be provided, with a maximum length of up to 17,150 mm, allowing flexible adjustment of the vehicle structure during loading and unloading. In terms of width, the basic specification is 2,500 mm, which matches the width of mainstream freight lanes. If it is necessary to transport overwidth goods (such as large prefabricated parts and special machinery), models with a width of 3,000 mm or more can be customized. Among them, the low-bed series can have a maximum width of 3,500 mm, enabling the transportation of goods without additional disassembly. For height, the conventional overall height of the vehicle is approximately 4,200 mm, which complies with the road height limit requirements. The working platform height of the low-bed variant is only 850-1,200 mm, which greatly lowers the threshold for loading and unloading heavy goods, and is especially suitable for loading and unloading with the assistance of equipment such as forklifts and cranes.

2. Gooseneck Disc Brake Semi-trailer: Load Capacity Specifications Cover Full Range of Light, Medium and Heavy Needs

In terms of load-bearing performance, the product covers a full range of rated load capacities from 30 tons to 150 tons. Conventional models mainly have specifications of 38,500 kg (38.5 tons) and 50,000 kg (50 tons), which can meet the daily transportation of medium and heavy goods such as building materials, coal, and general machinery. For large construction equipment (such as excavators and road rollers) and bulk heavy materials (such as steel coils and castings), a customized large detachable gooseneck low-bed version can also be provided, with a rated load capacity of up to 100 tons or more, easily handling the transportation of overweight goods. In terms of gross vehicle weight (GVW), the vehicle strictly complies with road transportation regulations, generally not exceeding 49,000 kg (49 tons). Specifically, it can be flexibly adjusted according to the number of axles and the load level of tires, ensuring load capacity while avoiding exceeding the road traffic load limit.

3. Gooseneck Disc Brake Semi-trailer: Axle and Tire Configurations Ensure Driving Stability

The axle configuration focuses on "load-bearing capacity and driving smoothness". Common basic models include 2-axle and 3-axle versions, with single-axle load capacities of 13 tons, 16 tons, or 18 tons respectively, which can meet the transportation needs of most medium and heavy goods. For transportation scenarios involving overweight and overwidth goods, 4-axle, 5-axle, or multi-axle models can also be provided. By distributing the load through multiple axles, the pressure on a single axle is reduced, and the service life of the axles is prolonged. The tires adopt two mainstream specifications: 12R22.5 and 315/80R22.5, both of which are all-steel heavy-duty tires with wear-resistant, puncture-resistant, and high-temperature-resistant properties. The number of tires matches the number of axles: conventional 2-axle models are equipped with 8 tires, 3-axle models with 12 tires, and multi-axle models can have an increased number of tires according to the configuration. This ensures stable vehicle support and reduces the risk of jolting and unbalanced loading during driving.

4. Gooseneck Disc Brake Semi-trailer: Detailed Specifications Enhance Durability and Operability

The product uses high-quality industry-brand key components. The kingpins come in common specifications of 2 inches and 3.5 inches, with the cooperative brand being the world-renowned JOST. They feature high connection strength, smooth insertion and removal, and no easy loosening or wear after long-term use, ensuring stable connection with the tractor. The landing gears also adopt the JOST brand, with a rated lifting capacity of 30 tons and a maximum static lifting capacity of 80 tons. Even when carrying fully loaded goods, they can stably support the vehicle body, facilitating the separation or docking operation between the tractor and the semi-trailer. The suspension system is configured with air suspension as standard, which has good shock absorption effect, can effectively buffer road jolts, and reduce the risk of cargo collision damage. At the same time, mechanical suspension is available as an option, suitable for scenarios sensitive to cost or short-distance high-frequency transportation. Both types of suspensions have undergone durability tests and can have a service life of more than 8 years.
