新型滾(gun)輪通過輪轂上的(de)機械結構與彈性體固定的(de)免粘膠(jiao)設計 , 可 以(yi)防止彈性體脫落，提高了滾(gun)輪的(de) 使用(yong)(yong)壽命，減少工(gong)作人員對該(gai)電梯(ti)(ti) 用(yong)(yong)滾(gun)輪的(de)拆解(jie)和組裝(zhuang)工(gong)作，節省人工(gong)成本，也減少維保人員在電梯(ti)(ti)井(jing) 道內(nei)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.
