Abstract: A mast-climbing robot has first and load-bearing assemblies, at least one linear actuator connected between the assemblies for changing their vertical spacing, and a respective clamp on each load-bearing assembly that can secure the respective load-bearing assembly on the mast and release the respective load-bearing assembly therefrom. Each clamp has two bearing points on the respective load-bearing assembly, at least one flexible belt that extends between the two bearing or attachment points and circumferentially around the mast, and at least one clamping actuator with which the length of the at least one belt can be increased and decreased between the bearing or attachment points to tighten lock the respective belt about the mast and thereby lock the respective assembly on the mast.

Abstract: The invention relates to a climbing robot for masts/towers (1), in particular for wind turbines, comprising at least one first load-bearing device (5) and at least one second load-bearing device (6), wherein the distance between the load-bearing devices (5, 6) can be changed in the vertical direction by means of at least one linear drive (7, 8), and each load-bearing device (5, 6) comprises at least one clamping device (9, 10, 11) by means of which the respective load-bearing device (5, 6) can be clamped firmly on the mast/tower (1) and released from the mast/tower (1), in which at least some of the clamping devices (9, 10, 11), preferably each of the clamping devices (9, 10, 11), comprises at least one band element (9), which extends between two contact or fixing points (10, 11) arranged on the load-bearing device (5, 6) and can be placed in a flexible manner around a mast/tower (1) in the circumferential direction and against the circumferential surface of the latter and comprises at least one clamping driv
