The new type hydraulic prop reduces the accidents due to the seal leaking by using seal-compensation and seal-swelling, and reduces seal change times and maintenance times. 新型液壓支柱採用密封補償和密封脹緊等密封方式,可減少因密封泄漏而造成的冒頂等事故隱患,減少密封更換次數及維修次數。
Hidden failures can be early found and maintenance cost can be cut through the monitoring of machine status and the use of failure diagnostic technique. 通過對機器狀態的監測及故障診斷技術的應用,可以及早地發現事故隱患,減少維修成本。
