新型滾(gun)輪(lun)通過輪(lun)轂(gu)上的(de)機械結構與(yu)彈性體固定的(de)免粘膠設計 , 可(ke) 以防止(zhi)彈性體脫(tuo)落，提(ti)高(gao)了滾(gun)輪(lun)的(de) 使用(yong)壽命，減(jian)少(shao)工(gong)(gong)作(zuo)人員對該電梯 用(yong)滾(gun)輪(lun)的(de)拆解(jie)和組裝(zhuang)工(gong)(gong)作(zuo)，節省人工(gong)(gong)成本(ben)，也減(jian)少(shao)維(wei)保(bao)人員在電梯井 道內停留時間，降低安(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.
