新型(xing)滾輪(lun)通(tong)過(guo)輪(lun)轂上的機械結構與彈性(xing)體固(gu)定的免(mian)粘膠設計 , 可 以防止彈性(xing)體脫落，提高了滾輪(lun)的 使用(yong)壽命(ming)，減少工(gong)作(zuo)人員對該(gai)電梯 用(yong)滾輪(lun)的拆解和(he)組裝工(gong)作(zuo)，節(jie)省人工(gong)成本，也減少維保人員在電梯井 道(dao)內停留(liu)時間，降低安全風(feng)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.
