Zusammenfassung:An apparatus for inserting a shut-off device 9 laterally into a pipe via a branch 48 which is inclined at an obtuse angle to the pipe, comprises a housing 1 for connection at one end to the branch and containing a first carriage 6 which is movable relative to the housing to a forward position projecting from the housing into the pipe and includes a receptacle for the shut-off device and a guide member 8 for guiding the shut-off device out of the receptacle, a second carriage 10 which is movable relative to the first carriage and is connected to the shut-off device by an insertion jack 13, and displacement means for first moving the first carriage to its forward position, the second carriage moving with the first carriage, and for then moving the second carriage relative to the first carriage to move the shut-off device out of its receptacle further into the pipe, the insertion jack finally being operated to move the shut-off device into position in the pipe.
