Jumping elevator and jumping method thereof

According to the jumping elevator and the jumping method thereof, the highest service floor of the jumping elevator is the top of a steel platform, operators on the steel platform can directly reach the highest operation plane, so that the operators on the steel platform can directly reach the top of the steel platform safely, quickly, efficiently and conveniently, and the operation difficulty in actual engineering can be solved; moreover, parts on the top of the hoistway, such as the limit position switch, can be naturally moved to a new position along with the jumping of an elevator machine room, and additional moving and mounting work is not needed, so that the elevator stopping time during the jumping period of the elevator is effectively shortened; in addition, after the top of the building is sealed, a jumping elevator machine room can be reserved to serve as a final machine room of a formal elevator, materials are saved, and the construction period is shortened. 本发明公开了一种跃升电梯及其跃升方法，其最高可服务楼层就是钢平台顶部，钢平台上的
