新型滾輪(lun)通過輪(lun)轂上的機械結構與彈性(xing)體固定的免粘(zhan)膠設計 , 可 以(yi)防止(zhi)彈性(xing)體脫落，提(ti)高了滾輪(lun)的 使用壽命，減(jian)少工(gong)作人員(yuan)對該電梯(ti) 用滾輪(lun)的拆解和組裝(zhuang)工(gong)作，節省人工(gong)成(cheng)本，也減(jian)少維保人員(yuan)在電梯(ti)井 道內停留時間，降低安全(quan)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.
