Abstract (en)
[origin: EP0320445A2] For pulling down walls, use is made of a C-shaped pulling-down implement having two tips (15, 16) lying coaxially opposite one another. One tip body (18) contains a hydraulically actuable piston (36), by means of which the tips are pressed into the masonry structure until it cracks. The implement body (1) is of lightweight design and can be carried by one man. High-pressure fluid is supplied through hoses from a remotely arranged high-pressure source. <??>As a result, it is possible to create a portable pulling-down implement which can be operated without lifting gears. <IMAGE>
