新型滾(gun)輪通(tong)過(guo)輪轂上的機械結構與彈(dan)性(xing)體(ti)固(gu)定(ding)的免粘膠設計 , 可 以防止彈(dan)性(xing)體(ti)脫落(luo)，提高了滾(gun)輪的 使(shi)用(yong)(yong)壽命，減少工作人員對該電(dian)(dian)梯 用(yong)(yong)滾(gun)輪的拆解和組裝(zhuang)工作，節省人工成本，也減少維保人員在電(dian)(dian)梯井(jing) 道內(nei)停留時間，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.
