新型(xing)滾(gun)輪(lun)(lun)通過輪(lun)(lun)轂上的(de)機械結構(gou)與彈性體(ti)固(gu)定的(de)免(mian)粘膠設(she)計 , 可 以防止彈性體(ti)脫(tuo)落，提高了滾(gun)輪(lun)(lun)的(de) 使用壽命，減少工作人(ren)員對該(gai)電梯 用滾(gun)輪(lun)(lun)的(de)拆解和組裝工作，節省人(ren)工成本(ben)，也減少維保人(ren)員在電梯井 道內停留時間，降低(di)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.
