新型滾(gun)(gun)輪(lun)通過輪(lun)轂(gu)上的(de)機械(xie)結構與彈性體固定(ding)的(de)免粘膠設計 , 可 以(yi)防(fang)止彈性體脫(tuo)落，提高了滾(gun)(gun)輪(lun)的(de) 使用壽命，減少工(gong)作人員(yuan)對該(gai)電梯(ti) 用滾(gun)(gun)輪(lun)的(de)拆解(jie)和組裝工(gong)作，節省人工(gong)成本，也減少維保人員(yuan)在電梯(ti)井(jing) 道內停留時間，降(jiang)低(di)安全風險(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.
