We are a manufacturing enterprise dedicated to R&D, manufacturing and trading of construction machinery parts. We produce a complete set of spare parts for bulldozers and excavators. We not only provide personalized customized raw materials according to customer needs, but also provide personalized customized models of construction machinery parts, oem heavy equipment parts.
Yintai Machinery has rich experience in manufacturing engineering machinery parts, and our construction machinery parts products have won a good reputation all over the world for their high quality and excellent service. We are an excellent construction machinery parts suppliers. In order to ensure excellent product quality and price competitive advantages, from raw materials to production, technology and management, we have been constantly innovating and improving our construction machinery parts.
Designed for high-impact and high-loading applications, such as mining, demolition, heavy constructionans waste disposal, PPR track link assy is an exclusive design that mechanically locks the link to the pin. Increases joint sealability in applications where end-play growth can exceed the capacity of the seal. It helps maximize the undercarriage wear life and minimize the operating costs.
Advanced Germany KUKA automatic machining center, horizontal and vertical CNC machining ensure the accuracy of assembly dimensions of our rollers. This is to maximize the life span of each component and minimize production cost. Each roller shell is carefully heat treated to ensure long wear life and stress resistance. Shaft uses high-quality manganese steel, quenched and tempered, high-frequency processing, it can meet the needs of high-intensity operations. Panasonic automatic welding robot from Japan makes sure we have steady and good welding quality.
The Excavator undercarriage is composed of sprocket, track link assy, idler, track roller, carrier roller and so on. Sprocket is a profiled wheel with teeth or cogs, that mesh with a chain, track or other perforated or indented materials. Professional quench-tempering processes guarantees excellent mechanical properties, high strength and superior wear resistance avoid bending and breakage. Strict quality management ensures the effective and stable products.
Idler is an important part of Excavator and Bulldozer undercarriage. It guides the track in and out of the track rollers. Our professional tempering and medium frequency quenching treatment ensure the sufficient hardness of the core and abrasion resistance of external surfaces.High-quality material guarantees the quality and consistency of our idler.
One important part of the undercarriage is carrier roller, it can support the conveyor belt and the weight of the material. The quality of carrier rollers will influence the working life of Excavator and Bulldozer.We have complete production line and professional designers and working team.Panasonic automatic welding robot from Japan, making sure we have steady and good welding quality. We can also produce any requested parts according to your blue print or samples.
Grader blade and side cutter complement each other to carry out the soil cutting, scraping, leveling delivery operations, shaping and maintenance of the gravel road, topsoil, scraping slope, leveling and help prevent damage.We offer a wide selection of blades and side cutters manufactured from several grades of high carbon and boron steel.Through professional quench-tempering processes to guarantee excellent mechanical properties, high strength and superior wear resistance to avoid bending and breakage.Meet OEM and industry standard for earthmoving machinery and equipment.Strict quality control system complying with the stringent ISO System.35 years' experience in Excavator & Bulldozer spare parts manufacturing.Available dimensions for all standard grader blades or customized dimensions.
The segments compose a sprocket rim, which is a profiled wheel with teeth or cogs that mesh with a chain, track or other perforated or indented materials.Professional quench-tempering processes guarantees excellent mechanical properties,high strength and superior wear resistance to bending and breakage. Reliable and long life-time guarantee, develop and manufacture follow or even exceed original ones.
Our Bucket Teeth is casting from wear-resistant alloy steel. Its wear resistance is four or five times as high as that of common high manganese steel teeth. It has high toughness and is not easy to break in the impact process. We offer a wide variety of tip shapes and sizes, ensuring we have what you need for your specific application.Through professional heat treatment processes to guarantee excellent mechanical properties,high strength and superior wear resistence to bending and breakage.Hardness 48-53HRC for reduced wear and longer life.Our quality control department is equipped with the first-class testing and inspection facilities, such as spectorometer imported from Germany, Optical metallographic microscope, Hydraulic universal tensile strength machine, Low temperature impact testing instrument, Bush hardness tester and magnetic particle inspector.OEM number and maritime logistics guidance services.
We manufacture Grade 10.9, 12.9 of track bolt and nut, plow bolt and nut, segment bolt with nut, rolelr bolt and nut and so on. If you have a mass of count products with new type, we also can develop the new one for you. Please give us the particular information of the type you want, and we’ll do our best to help you.
Our track shoe adopt precision processing and professional heat treatment technology to reach best resistance and maximum extent loading capacity as well as anti-cracking. 30+ years' experience in Excavator & Bulldozer spare parts manufacturing shows our strong experience in machining procession and quality control.
The quality and working life of oil links depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. We take strict quality management from raw materials to packing. Strict detecting system and advanced inspection equipment ensures the high quality of our track links.Professional mesh belt furnace heat treatment makes our products have good combination mechanical properties. Additional medium frequency heat treatment makes the surface of our links enhanced.
Track roller is an important part of undercarriage, it has two kinds of welding methods, one is traditional and the other is friction-welding. Friction-welding track roller is better in the wear-resistance and has a longer working lifetime. Roller bodies of traditional track roller are connected by the welding rod, but the friction ones are connected by the friction between rollers' bodies. So the friction-welding roller will be added more raw material to make sure the roller is perfect to the standard size after welding. For the traditional rollers, the welding is done after two processes of machining, so the size of the inner parts is not so precise as friction-welding ones. For the friction-welding ones, after the welding, there is one more precise machining with concentric locating to make sure the conformity of inner size, this means the inner parts are more precise with a higher standard.
