新型(xing)滾輪(lun)通過輪(lun)轂上的機械結構(gou)與彈性體固定的免(mian)粘(zhan)膠設計 , 可 以防止(zhi)彈性體脫落(luo)，提高了滾輪(lun)的 使用壽命，減少工作人(ren)員對該電(dian)(dian)梯(ti)(ti) 用滾輪(lun)的拆解和組裝工作，節(jie)省人(ren)工成(cheng)本(ben)，也減少維保人(ren)員在電(dian)(dian)梯(ti)(ti)井 道內停留(liu)時間，降低安全風險。 

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.
