Idler is undercarriage part of Crawler Crane, also is called Guide Wheel or Guide Roller, it is made of 35CrMo or 35CrNiSiMo, under casting and heat treatment. Our Idlers use good hardenability steel, so that the crawler crane could reduce the wear of the idler, that is important to ensure high-quality work and high efficiency, and has good impact toughness, a certain depth of quench layer and transition layer to improve the bearing capacity, wear resistance and resistance to contact fatigue. Through whole quenching & high temperature tempering, then the integral key surface quenching. We take advanced equipment and technology, and carry out strict tests to ensure the quality, such as chemical composition, hardness, impact toughness, precision, function, and so on. The products mainly have these processing methods: casting or forging, machining, heat treatment such as tempering, quenching, medium frequency quenching, harden.
