description The utility model discloses a ladder for moving up and down in a cable channel, comprising a main ladder and a subordinate ladder, wherein a plurality of fixing holes are symmetrically arranged on a main ladder leg between transverse rods on proper heights of the main ladder; clamping sleeves are clamped on positions in correspondence with the fixing holes, and the clamping sleeves are fixedly connected with the fixing holes through screws; supporting iron sheets are welded at the top end of the subordinate ladder; the supporting iron sheets are hinged in the openings of the clamping sleeves through hinged shafts; and a telescopic leg is respectively sleeved in two supporting legs of the subordinate ladder. The ladder for moving up and down in the cable channel disclosed by the utility model is rational in structure, convenient in use and easy in regulation, and is capable of guaranteeing the security of the constructors to move up and down in the cable channel for construction, and protecting the cable proce
