新型滾輪(lun)通過輪(lun)轂上(shang)的機械結構與彈(dan)性體固定的免粘膠設計 , 可(ke) 以防止彈(dan)性體脫落，提高了滾輪(lun)的 使用壽(shou)命，減(jian)少工(gong)作人員(yuan)對(dui)該電梯(ti) 用滾輪(lun)的拆解和組裝工(gong)作，節省人工(gong)成本(ben)，也減(jian)少維(wei)保(bao)人員(yuan)在(zai)電梯(ti)井 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.
