  • Device for inspecting, sampling or extracting at a precise spot beneath a slab
    Patent number: 6951442
    Abstract: A tool (7) for sampling or extracting the contents of a pit (4) is suspended from a cable (8) passing through a narrow opening (3) in a slab (2) covering the pit. A crosspiece (13) hooked to guide cables (11) which converge on it makes it possible to displace the lifting cable (8) under the slab (2) according to different movements imposed by winches (10). Thus it is possible to move the tool (7) to the desired point with great precision and without having to descend into the pit (4).
