起重机在使用中，各运动部件不可避免的会产生磨损、连接件松动、油液变质、金属结构产生腐蚀，从而引起起重机的技术性能、经济性能和安全性能不同程度的降低。因此，在起重机零件磨损尚未达到影响起重机产生故障程度之前，为预防和消除隐患，保证起重机经常处于良好的状态，应对起重机进行维护和保养。
In the use of crane, the moving parts will inevitably produce wear, loose connections, oil deterioration, metal structure corrosion, which will cause the technical performance, economic performance and safety performance of the crane to reduce in varying degrees. Therefore, in order to prevent and eliminate the hidden danger and ensure that the crane is always in good condition, the crane should be maintained and maintained before the wear of crane parts has reached the extent of affecting the fault of the crane.
做好起重机的维护和保养，能起到如下作用。
Do a good job of crane maintenance, can play the following role.
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. Ensure that the crane often has good technical performance, is the normal and reliable work of each mechanism, improve its intact rate, utilization rate and other management indicators.
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 performance, strengthen the protection of structural parts, keep the connection firm, electro-hydraulic components operate and function normally, avoid abnormal vibration due to mechanical and electrical factors, and meet the requirements of 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. In line with the relevant environmental protection standards of the state and departments.
5、合理、有效地延长起重保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 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，从而延长起重机使用寿命。
5. Reasonable and effective extension of crane service life. Through the maintenance of the crane, effectively extend the repair interval of the crane or mechanism, including the overhaul cycle, so as to extend the service life of the crane.
