A combination horizontal and vertical rope-pulling device that uses a hydraulic braking assembly that is mounted on a vertical frame to support an endless rope that is placed over a number of pulleys. A pivoting boom is attached at the top of the frame. In the vertical mode, the rotating boom is positioned at an angle extending rearward from the vertical frame. The rope passes over a number of pulleys to simulate a vertical rope for climbing. In the horizontal mode, the rotating boom is rotated down so that it is parallel to the vertical frame. The rope follows the downward run of the boom and around the pulleys. In this way, the user can use the machine as a horizontal rope-pulling machine.
