The invention discloses a Z-shaped aluminum alloy crawling ladder. The crawling ladder comprises a second supporting plate and handrails, wherein one handrail is arranged on each of the left side and the right side of the upper end of the second supporting plate, the second supporting plate and the handrails are fixed in a spot welding mode, one side plate is arranged at each of the front end and the rear end of the right side of the lower end of the second supporting plate, stepping plates are arranged in the side plates on the two sides, first supporting plates are arranged at the lower ends of the side plates on the two sides. According to the ladder, a mode that handrails are fixed through welding or bolts is changed to an existing mode that when a supporting rod is subjected to an acting force, the borne acting force can be buffered to a certain extent through a buffer piece in the supporting rod, so that the handrails are not in direct contact with a user, and the problem that the palm of the user is injured due to large force when the user presses the handrails is solved; and four supporting rods in each handrail are all provided with buffer pieces, so that direct rigid contact is avoided during use, and the problem that the crawling ladder is inconvenient to use due to the gravity action is effectively relieved.
本发明公开了一种Z形铝合金爬梯，包括第二支板与扶手，所述第二支板上端左右两侧各设置有一个扶手，所述第二支板与扶手点焊固定，所述第二支板下端右侧前后两端各设置有一根侧板，两侧所述侧板的内部设置有踏板，两侧所述侧板下端设置有第一支板，本发明中通过将扶手采用焊接或者螺栓固定的方式更改为现有的在支杆受到作用力时，可以通过支杆内部的缓冲件使得受到的作用力可以进行一定的缓冲，不会使得扶手与使用者直接接触，避免了使用者在压动扶手时由于力道较大使用者手掌出现损伤的问题，而且在扶手内部四根支杆均设置有缓冲件，这样在使用时不会出现直接的硬性接触，从而有效的缓解了由于重力作用导致该爬梯使用不方便的问题。
