During the use of the lifting platform, when the elevator rises to the high point of the equipment, it often appears some slight swaying, which is actually a normal phenomenon. Generally speaking, the swing range of the lifting platform will vary according to the height. Under the same conditions, the fixed lifting platform is stable, and the swing range of other equipment is also limited, which will basically not cause construction accidents.

当然，为了确保施工，在操作升降平台前，一定要做好这些检查事项：

Of course, in order to ensure construction safety, these inspection items must be done well before operating the lifting platform:

1、检查架体结构，应查看基础及标准节连接螺栓紧固情况，螺栓按规定设置双螺帽或弹簧垫；各部位焊缝完好无裂纹；附着杆件应按照说明书要求的材质、规格设置，不应任意更改。检查过程中发现，有用钢筋代替螺栓，钢筋两端分别焊个钢筋头代替螺帽的现象时，要注意了，这种做法是非常危险的。

1. Check the frame structure, check the fastening of the connecting bolts of the foundation and standard sections, and set double nuts or spring washers for the bolts as required; Welds at all parts are intact without cracks; The attached rods shall be set according to the materials and specifications required in the instructions and shall not be changed arbitrarily. In the process of safety inspection, it is found that the reinforcement is used to replace the bolt, and a reinforcement head is welded at both ends of the reinforcement to replace the nut. This practice is very dangerous.

2、检查升降平台基础部位是否有积水，是否有下沉迹象，检查过程中发现有装在一层楼板上的升降平台，检查地下室的顶撑系统及计算方案；检查接地系统是否符合要求；绶冲器(弹簧)应齐全有用；底笼围接严密无破损；升降机底层进出口应有防护棚。

2. Check whether there is ponding at the foundation of the lifting platform and whether there is any sign of sinking. During the inspection, it is found that there is a lifting platform installed on the first floor. Check the top support system and calculation scheme of the basement; Check whether the grounding system meets the requirements; The ribbon punch (spring) shall be complete and useful; The enclosure of bottom cage is tight without damage; There shall be protective shed at the bottom entrance and exit of the elevator.
