、硬化層壓碎和點蝕。車輪的材料一般采用ZG430-640鑄鋼。為了提高車輪表麵的耐磨強度和壽命，踏麵應進行表麵熱處理，要求表麵硬度為HB300-350，淬火深度不少於20mm。起重機車輪組:起qi重zhong機ji運yun行xing機ji構gou車che輪lun的de水shui平ping偏pian斜xie值zhi是shi起qi重zhong機ji重zhong要yao的de技ji術shu參can數shu，偏pian斜xie值zhi超chao差cha會hui造zao成cheng啃ken軌gui，增zeng大da運yun行xing阻zu力li

、工藝措施也相對簡單的設計結構是:將車輪裝配到支架上組成車輪組，例如角型軸承箱車輪組和台車式45°剖分軸承箱車輪組，在起重機主結構上，安裝調整車輪水平偏斜合適後固定。
