Claim:
An extractor for removing an anchorage, said anchorage being installed in the ground and said anchorage having a longitudinal axis, said extractor comprising: a. a main body; b. a rack slidingly mounted to said main body; c. a shaft rotatively mounted to said main body; d. a sprocket fixedly mounted to said shaft, said sprocket engaging said rack; e. a driving wheel fixedly mounted to said shaft; f. a housing rotatively mounted to said shaft, said housing being rotatable in a first direction and in a second direction; g. a first lever mounted to said housing for rotating said housing in said first and second directions; h. a first lever-lock slidingly mounted to said housing, said first lever-lock being configured to drivingly engage said driving wheel in only one of said first and second directions in which said housing can be rotated; i. a connector configured to engage said anchorage, said connector being connected to said rack; j. a base connected to said main body, said base being configured to be in contact with said ground; k. an elongated guiding member connected to said main body and extending substantially parallel to said main body, said guiding member comprising a plurality of positioning holes, each of said positioning holes corresponding to a different angular position of said main body; l. a sliding structure slidingly mounted to said guiding member, said sliding structure comprising a locking member for selectively engaging one of said positioning holes; m. a pivoting member pivotally connected to said, sliding structure and to said base; wherein when said housing is rotated in said only one of said first and second directions, said first lever-lock drivingly engages said driving wheel and causes said shaft and said sprocket to rotate, and wherein the rotation of said sprocket drives said rack and said connector upwardly, thereby pulling said anchorage from said ground.
