新型滾輪通過輪轂上的機械結構(gou)與彈(dan)性(xing)體固(gu)定的免粘(zhan)膠(jiao)設計(ji) , 可(ke) 以防止彈(dan)性(xing)體脫落，提高了滾輪的 使用壽命(ming)，減少工作(zuo)人員(yuan)(yuan)對該(gai)電(dian)梯 用滾輪的拆解(jie)和組裝工作(zuo)，節省人工成(cheng)本，也(ye)減少維保人員(yuan)(yuan)在電(dian)梯井 道內停留(liu)時間(jian)，降(jiang)低安全風險。 

New roller can prevent elastomer fall off by means of the mechanical structure and elastomer fixed wheel surface viscose design,improve the lifetime of roller,reduce operator disassembly and assembly to save labor cost,also reduce the staying time inside of the elevator shaft and reduce the risk.
