SUBSTANCE: shaft loading machine consists of radial telescopically extension-type frame of box construction, which consists of middle main part of inverted T-shaped construction and two telescopically extension-type side parts with extension hydraulic jacks arranged inside them. On flanges of middle main part there arranged is self-propelled truck to which telescopically extensible handle is attached with possibility of restricted angular turn by means of two control hydraulic jacks hinged to self-propelled truck and to telescopically extensible handle. Handle consists of main and telescopically extensible parts and connected to each other by hydraulic extension jack arranged inside telescopically extensible part. Controlled grab bucket is hinged on lower end of telescopically extensible part with possibility of angular turn. Self-propelled carriage of angular movement is located on annular monorail mounted on upper part of suspension downhole casing. Independent movement of machine in vertical plane separately from sinking platform is performed by means of two-drum small-size winch mounted on outer side of upper storey of sinking platform, and movable central axis.
