ABSTRACT:
A climbing device for climbing columns such as girders having flanges. The devices are worn in pairs on the feet of the climber and each is equipped with a gripping member having spaced apart jaws adapted to grip the column flange. The gripping member on each device is mounted on the foot-attached or base member for selective swinging between two positions, one a climbing position in which each pair of jaws extends laterally inwardly of the respective foot and the other a retracted position in which the jaws extend laterally outwardly and behind the heel of the climber's foot so as to be out of the way when not used for climbing. Means is provided for selectively locking the gripping member to the base member in either of said positions.
