Description

Technical Field

[0001] The utility model belongs to the technical field of lifting platforms, and particularly relates to an overhead traveling lifting platform. Background Art

[0002] This type of lifting platform is commonly used in occasions that require frequent vertical handling, such as on production lines in factories or in warehousing facilities where goods need to be lifted from the ground to different floors. When it rises to a certain height, it is not convenient for workers to pick up tools.

[0003] According to the authorized publication number CN217126863U, an overhead traveling lifting platform is disclosed. By setting a motor, the output end of the motor drives a winding disc to rotate, and then the winding disc drives a nylon rope through a driving pulley and an auxiliary pulley to play an auxiliary tool-picking effect through a hook, solving the problem that when forgetting to carry a certain tool after lifting, due to the lack of a structure for auxiliary tool-picking, it is necessary to lower the lifting platform to pick up the tool, which is not only troublesome but also time-consuming and laborious, achieving the effect of auxiliary tool-picking.

[0004] In the above patent, the lifting function and the function of picking up tools through a nylon rope are realized, but its bottom stability is not high. Workers will move back and forth in the working area during work, causing shaking and prone to accidents. It is not convenient for workers to pick up items. Moreover, when an item accidentally slides when lifted by a rope by a worker, the lack of a support structure and a braking structure is likely to cause safety accidents. For this reason, we propose an overhead traveling lifting platform. Summary of the Utility Model
