新型滾(gun)輪(lun)(lun)通過(guo)輪(lun)(lun)轂上的(de)機械結構與彈(dan)性體固定的(de)免粘膠設(she)計(ji) , 可 以防止彈(dan)性體脫落，提高了(le)滾(gun)輪(lun)(lun)的(de) 使用(yong)壽命，減少(shao)工(gong)作人員(yuan)對該電梯 用(yong)滾(gun)輪(lun)(lun)的(de)拆(chai)解和組裝工(gong)作，節省人工(gong)成本，也減少(shao)維保人員(yuan)在電梯井 道內停留時(shi)間，降(jiang)低(di)安(an)全風險(xian)。 

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.
