Abstract

1. Apparatus for the pulling of bore hole tubes (5, 6) from a bore hole and the release of the screw coupling (breaking) by means of a fluid-operated working piston/cylinder unit (cylinder), characterised by a pulling cylinder (1) operating, together with the breaking device, in the axial direction of the bore hole tubes (5, 6), supported, at its ends, on the one hand on a base plate (11) and on the other hand on a breaking device (17), gripping jaw units (18, 19) arranged axially one after another, rotatable radially in opposite senses and comprising two gripping cylinders (34, 35) by means of which the bore hole tubes (5, 6) are gripped, and a release cylinder operable in the peripheral direction in relation to the bore hole tubes (5, 6) and supported on each of the gripping jaw units.
