新型滾輪通過(guò)輪轂上的機(jī)械結(jié)構(gòu)與彈性體固定的免粘膠設(shè)計(jì) , 可 以防止彈性體脫落，提高了滾輪的 使用壽命，減少工作人員對(duì)該電梯 用滾輪的拆解和組裝工作，節(jié)省人工成本，也減少維保人員在電梯井 道內(nèi)停留時(shí)間，降低安全風(fēng)險(xiǎn)。 

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.
