Key Features and Engineering Excellence

The trailer coupling is built to withstand extreme conditions, with its core components forged from high-grade 42CrMo material. This alloy steel undergoes quenching and tempering to achieve a hardness of HRC 28–32, ensuring exceptional strength and resistance to wear. The design incorporates a traction force of 280 kN, making it suitable for heavy-duty applications such as commercial trucking and logistics.

With a cylinder working pressure of 0.8 MPa, the coupling maintains consistent performance under high-stress scenarios. Its installation dimensions comply with European standards, ensuring compatibility with a wide range of towing systems. The air pipes feature an 8mm diameter, optimizing airflow efficiency and reducing the risk of pressure loss during operation.

Advantages of the Trailer Coupling

One of the standout advantages of this trailer coupling is its versatility. It is designed to accommodate various trailer types, including box trailer coupling and truck trailer coupling, making it a universal solution for industries such as construction, agriculture, and transportation. The coupling’s high tensile strength and corrosion resistance ensure long-term reliability, even in harsh environments.

The black trailer coupling variant, for instance, is ideal for applications where aesthetics and durability are equally important. Its matte finish not only enhances visual appeal but also provides additional protection against environmental factors. Additionally, the coupling’s compliance with European standards ensures seamless integration into global supply chains, reducing the need for custom modifications.
