Focusing on the pain points of heavy-duty working conditions in engineering machinery track walking systems, we have completed the technical deepening and process upgrading of track plate bolt products. Through the full chain technical polishing of material properties, thread design, and heat treatment processes, we have significantly improved the comprehensive performance of product anti loosening, wear resistance, and fatigue resistance, providing reliable connection technical support for various types of engineering machinery walking systems.

In response to the operational characteristics of track shoes being subjected to alternating loads, vibration impacts, and sediment erosion for a long time, the company has carried out targeted optimization from the technical source. High strength alloy structural steel is selected as the material, which combines high tensile strength and excellent impact toughness after precise quenching and tempering heat treatment. It can withstand continuous impact loads during equipment walking and operation, effectively reducing the risk of fracture; Optimize thread profile design and high-precision machining process, strictly control thread fit clearance, improve meshing tightness and self-locking anti loosening performance, and reduce the risk of loosening and slipPing under long-term vibration conditions; At the same time, it can be equipped with various surface anti-corrosion and wear-resistant treatment processes to enhance the product's ability to resist rust and abrasive wear, and adapt to complex operating environments such as mines, construction sites, and wilderness.

Relying on a mature technology system, the company's Track plate bolts can be widely adapted to connect track assemblies of excavators, bulldozers, and other models of global mainstream construction machinery brands such as Caterpillar, Komatsu, Volvo, Daewoo, Shengang, Hyundai, and Liebherr. At the same time, corresponding specification Nuts are supplied to meet customers' one-stop procurement needs. In addition to standard specifications, the company also has the ability to customize non-standard technical specifications, and can customize product parameters according to special machine models and working conditions.

In terms of quality control, the entire series of Track shoe bolts are strictly produced in accordance with the ISO9001-2000 quality management system standard, and a full process quality traceability mechanism covering raw material verification, production process control, and finished product performance testing is established. Key indicators such as dimensional accuracy, mechanical properties, and surface quality are strictly verified batch by batch to ensure stable and consistent technical performance of the products leaving the factory. With self operated import and export rights, the company's track plate bolt products have been exported to dozens of countries and regions such as Europe, the United States, Canada, Australia, etc., and have gained wide recognition and praise from customers at home and abroad with reliable quality.

Ningbo Yiteng Engineering Machinery Co., Ltd. has always adhered to the business principle of "quality first, customer first, reasonable price, and reputation first", and continuously cultivated the core technology of specialized fasteners. In the future, the company will continue to promote the technological upgrading of core products such as track shoes and bolts, continuously expand product application scenarios and global market territory, steadily move towards modern management, enterprise scale, and brand internationalization, and provide more valuable connection technology solutions for the global construction machinery industry.
