The invention provides an adjustable steel ladder, and belongs to the technical field of crawling ladders. The device comprises a starting platform, two boundary beams, pedals and a connecting base, the two boundary beams are symmetrically arranged, the starting platform and the connecting base are arranged at the two ends of the boundary beams respectively and rotationally connected with the two ends of the two boundary beams respectively, the pedals are evenly arranged between the two boundary beams at intervals, and the middles of the two ends of the pedals are in threaded connection with rotating bolts. According to the steel ladder, the use safety of the steel ladder is effectively improved, the application range of the steel ladder is expanded, the steel ladder is convenient to use, the service life of the steel ladder is prolonged, the service life of the steel ladder is prolonged, the service life of the steel ladder is prolonged, and the service life of the steel ladder is prolonged. And the device is simple in structure, convenient to mount and dismount and high in overall structural strength, and the production, use and maintenance cost of the steel ladder is effectively reduced.
本发明提供一种可调节钢梯，属于爬梯技术领域。本发明包括起步平台、两根边梁、踏板以及连接座，两根边梁对称设置，起步平台和连接座分别设置在边梁两端，起步平台和连接座分别与两根边梁两端转动连接，若干个踏板均匀间隔设置在两根边梁之间，踏板两端中间螺纹连接有旋转螺栓，旋转螺栓两侧对称设置有调节螺栓，边梁表面对应设置有与旋转螺栓相配合的连接孔，连接孔两侧对称设置有与调节螺栓相配合的弧形调节孔，边梁下方设置加强组件，本发明有效提高了钢梯使用的安全性，扩大了钢梯的适用范围，且装置结构简单，安装拆卸方便，整体结构强度高，有效降低了钢梯的生产使用及维护成本。
