Hydraulic lift cargo elevators are fixed transportation equipment that lifts items from one height to another. Due to the large weight and volume of most lifted objects, the equipment of guide rail hydraulic lift cargo elevators manufacturers is safe and stable. Therefore, they belong to a special form of high-altitude work lifting platform and should be classified as lifting machinery. The correct maintenance methods for the equipment of the guide rail hydraulic elevator manufacturer are as follows:

非电气人员不得随意拆装电器，以防触电或误接；

Non electrical professionals are not allowed to disassemble electrical appliances at will to prevent electric shock or incorrect connection;

需要进入升降平台下面检修时，必须吊住升降台工作平台，以防升降台突然下降，造成人员伤亡；

When it is necessary to enter the lower part of the lifting platform for maintenance, the working platform of the lifting platform must be suspended to prevent sudden lowering of the lifting platform and causing casualties;

非人员不得任意调整溢流阀，液压系统中的每个元件都是在规定压力下工作时，任意调整溢流阀后，可能会造成液压系统非正常运转，对人机物都会有不必要的损伤；

Non professional personnel are not allowed to adjust the overflow valve arbitrarily. When each component in the hydraulic system is working under the specified pressure, arbitrarily adjusting the overflow valve may cause abnormal operation of the hydraulic system and unnecessary damage to human, machine, and objects;

卸液压系统任何部位之前，必须卸压，以免压力油喷出，工作台突然下滑；

Before unloading any part of the hydraulic system, pressure must be relieved to prevent pressure oil from spraying out and the workbench from suddenly sliding;

相应运动部件间均加注一些润滑油，延长轴承使用寿命；

Add some lubricating oil between the corresponding moving parts to extend the service life of the bearings;

检查液压油的油质和油位，升降货梯全程升起在这位置时，液压油面应高出箱底四十到五十毫米，液压机是否变暗发粘或有砂砾等异物，如有发现应及时更换120#液压油。

Check the oil quality and level of the hydraulic oil. When the cargo elevator is fully raised at this position, the hydraulic oil level should be forty to fifty millimeters higher than the bottom of the box. Check if the hydraulic press is dark, sticky, or has foreign objects such as gravel. If any, replace the 120 # hydraulic oil in a timely manner.

升降平台的正确使用方法，加上良好的维护保养以及施工的使用规范，可以帮助广大用户更好的发挥升降平台的作用，在保证工程质量的同时，提高工作效率，保障操作人员的！

The correct use of the lifting platform, coupled with good maintenance and safe use regulations during construction, can help users better play the role of the lifting platform, improve work efficiency, and ensure the safety of operators while ensuring engineering quality!
