新型滾輪(lun)通過輪(lun)轂上(shang)的機械結構(gou)與彈性體固定的免粘(zhan)膠設計 , 可 以(yi)防止彈性體脫落，提高了滾輪(lun)的 使用壽命，減(jian)少工作人(ren)員(yuan)對該電梯(ti) 用滾輪(lun)的拆(chai)解和組(zu)裝(zhuang)工作，節省人(ren)工成本，也(ye)減(jian)少維保人(ren)員(yuan)在電梯(ti)井(jing) 道內停(ting)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.
