Product Introduction
As a standardized industrial product, GB crane rails not only stipulate physical and mechanical performance indicators, but also clarify surface quality requirements. For example, the working surface of the rail head must not have cracks, scars, folds, or indentations or scratches with a depth exceeding 0.5mm; the edge of the rail bottom must not have burrs, flash, and other defects. Through strict surface quality inspections, the smoothness of the contact area between the rail and the wheel is ensured to avoid wheel-rail damage or operational failures caused by surface defects, thereby ensuring the safe and reliable operation of lifting machinery.
The high-hardness GB QU120 crane rail has become the core support for heavy-duty lifting operations with its excellent hardness performance. The large size and heavy-duty design lays a physical foundation for the high hardness characteristics. In terms of material selection, U75V material is often used, which makes the rail have high strength and toughness. After quenching, tempering and other heat treatment processes, the surface hardness is greatly improved, which can effectively resist the friction loss and impact stress caused by frequent rolling and braking of crane wheels.
Product Specifications
Product Application
The high hardness gives the QU120 crane rail strong wear resistance and deformation resistance, so that it can significantly reduce the wear rate and reduce the risk of failure such as surface cracks and crushing in heavy-duty scenarios such as port container lifting, steel plant billet transfer, and mine ore loading and unloading, even in the face of overweight loads and harsh working conditions. , thereby extending the service life of the track, reducing maintenance costs, and ensuring the long-term stable operation of large-scale lifting equipment.
In the field of crane rail manufacturing and export, GNEE RAIL has become an industry benchmark with its professional technical strength and reliable product quality. The company's products are widely used in various heavy lifting equipment, with excellent fatigue resistance and wear resistance, and can adapt to high-intensity working environments. Through continuous technological innovation and process optimization, GNEE continues to improve product performance to meet the international market's demand for high-quality rails. GNEE insists on being customer-centric, providing flexible customized services and efficient logistics support to ensure that customers can obtain satisfactory products in a timely manner and help global infrastructure construction.
