Fine copper bushing increases durability.
Due to the constant rolling friction between the crane bottom rollers and the flag of the crawler track shoes and to support the weight of the crawler crane body, the hardness, toughness and wear resistance of the track roller are necessary factors to ensure the service life. After precise overall quenching and tempering, the hardness of the entire bottom roller body conforms to the original technical standard. Through a series of inspections such as tensile tests, metallographic inspection, magnetic particle inspection, etc., the quality of each batch of lower rollers is guaranteed to be stable.
Use thickened high-quality copper bushings will inevitably increase some costs of crawler crane bottom rollers, but in the long-term use, it will be found that the wear resistance of the copper bushing and the shaft increases significantly, the possibility of oil leakage of rollers is greatly reduced, and the maintenance cost downtime period is reduced, the use benefits it brings far outweigh the increased costs. Good internal materials are easy to ignore when purchasing, but they are the core that affects the overall service life of track rollers. We firmly believe that details determine quality. Below are the available crawler crane bottom rollers: Hitachi bottom rollers, Sumitomo bottom rollers, Kobelco bottom rollers, IHI bottom rollers, Nippon Sharyo bottom rollers, Terex bottom rollers, American bottom rollers, Manitowoc bottom rollers, Demag bottom rollers, Link Belt bottom rollers, Liebherr bottom rollers, Sany, XCMG, Fuwa, Zoomlion bottom rollers.
