During the use of the crane, the moving parts will inevitably wear, loose connectors, oil deterioration and corrosion of metal structure, which will reduce the technical performance, economic performance and safety performance of the crane to varying degrees. Therefore, in order to prevent and eliminate hidden dangers and ensure that the crane is always in good condition, the crane shall be maintained before the wear of crane parts has reached the degree that affects the failure of the crane.
做好起重机的维护和保养，能起到如下作用。
The maintenance of the crane can play the following roles.
1、保证起重机经常具有良好的技术性能，是各个机构工作正常可靠，提高其完好率、利用率等管理指标。
1. To ensure that the crane often has good technical performance is the management index for each mechanism to work normally and reliably and improve its integrity rate, utilization rate and so on.
2、保证起重机具有良好的使用性能，加强结构件的保护，保持连接牢靠、电液元器件动作与功能正常，避免因机电因素产生异常震动，满足起重机正常使用要求。
2. Ensure that the crane has good service performance, strengthen the protection of structural parts, maintain firm connection, normal action and function of electro-hydraulic components, avoid abnormal vibration due to electromechanical factors, and meet the requirements for normal use of the crane.
3、保证起重机的安全使用。
3. Ensure the safe use of the crane.
4、符合国家及部门规定的有关环保标准。
4. Comply with relevant environmental protection standards stipulated by the state and departments.
5、合理、有效地延长起重机使用寿命。通过对起重机的维护保养，有效地延长起重机或机构的修理间隔时间，包括大修周期，从而延长起重
