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. 新型液壓支柱采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(guò)對機器狀態(tài)的監測及故障診斷技術(shù)的應用，可以及早地發(fā)現事故隱患，減少維修成本。
