新型滾輪(lun)(lun)(lun)通過輪(lun)(lun)(lun)轂上的機械結構與彈(dan)性體固定的免(mian)粘(zhan)膠設計 , 可 以防止彈(dan)性體脫(tuo)落，提高(gao)了滾輪(lun)(lun)(lun)的 使用壽命，減(jian)少(shao)工作人員對該電梯(ti) 用滾輪(lun)(lun)(lun)的拆(chai)解和組裝(zhuang)工作，節省人工成(cheng)本，也減(jian)少(shao)維保人員在電梯(ti)井 道內停留時(shi)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.
