Since workers need to carry a certain amount of tools or items each time they go back and forth, rigid metal ladders are generally used for the ladders. When the current ladders are in use, the soles of workers' shoes can easily slip when they step on the crossbar, posing a great safety hazard.

[0003] In this regard, the Chinese patent application number is CN202221118467.2, which discloses an underground working ladder, including: two side rods, which are distributed in parallel and at intervals; a plurality of cross plates, which are arranged between the two side rods at intervals along the length direction of the side rods, the upper surface of the cross plate is flat, and the upper surface of the cross plate is provided with a drainage groove running through the upper and lower surfaces of the cross plate; wherein, when the ladder is installed, the upper surface of the cross plate is placed horizontally. The utility model increases the contact area between the workers' soles and the ladder by using cross plates with flat upper surfaces to replace the cross bars of the circular tube body, reduces the probability of the workers' soles slipping during the climbing process, and at the same time, a drainage groove is opened on the cross plate to timely drain the water on the cross plate, thereby ensuring the workers' climbing.
