[0001] The utility model relates to the technical field of tower crane ladders, in particular to a tower crane ladder for people to climb which is easy to climb. Background Art

[0002] Tower crane is a commonly used lifting equipment on construction sites. It can also be called a tower crane. It is used to lift construction materials such as steel bars, wooden slats, scaffolding pipes, etc. It is an indispensable equipment in construction. The height of the tower crane is determined by the standard section of the installed tower crane. Each standard section is equipped with a ladder so that workers can climb the ladder to reach the work room at the top of the tower crane.

[0003] The ladders currently seen on construction sites are often fixedly connected to the tower crane with a fixed inclination. A uniform ladder inclination may not be suitable for all climbers and cannot be adjusted as needed. At the same time, when climbing a multi-section tower crane, the climbers will rest on the rest platform in the standard section of the tower crane, but the rest platform can only be used for the climbers to stand. The climbers' legs and feet are still under stress and they cannot get an effective rest. There are certain safety hazards in continuing to climb the tower crane with an unrested body.
