ABSTRACT:
A rope pulling machine is convertible into a walking machine, and has a machine frame composed of a pulling station movable back and forth and a gripping station connected to the pulling station via a main cylinder/piston arrangement, the pulling and gripping stations each having an auxiliary cylinder/piston arrangement for a gripper, and the two grippers are linked via bearing shafts to the auxiliary cylinder/piston arrangement. The grippers have clamping jaws aligned in a rope direction and linked via bearing shafts to the pulling and gripping stations, respectively. The bearing shafts are designed as detachable shafts, making the grippers exchangeable with walkers having the same bearing points and bearing shafts and which form a walk station and a slave station. The walkers have pawls engaging a rack alternately, and running gears guided on the rack. In the course of converting a rope pulling machine into a walking machine and vice versa, the machine frame, the cylinder/piston arrangements, and control device provided therefor remain intact and unchanged.
