Track-laying inspection vehicle for inspecting tunnel-like ducts

摘要

Track-laying inspection vehicle for inspecting tunnel-like ducts, gangways or shafts. The track-laying inspection vehicle is divided up into two individual track-laying units (1, 2), the front one (1) being steered. Control voltages (Ur1, Ur2) are produced from the constellation of the coupling parts (6, 7) and act on travel speed and direction of the rear individual track-laying unit (2) in such a way that it follows the travel movement of the front individual track-laying unit (1) to an optimum degree.
