【 摘 要 】

The landing doors are quite important to the safety of the passengers during waiting and using lifts. In order to know the safety situation of the lift landing doors after China's new regulations issued, the type test results of 647 landing door samples are summarized and analysed, including thickness analysis, static strength test analysis and impact test analysis. The result shows that the maximum elastic deformation can be fitted to have proportional relationship with the applied force, and the protrusion clearance into well after impact test of 89% doors are below half of the given limit in regulations.
