Apparatuses and methods for facilitating fastening of a fastener are provided. In one example, the apparatus includes a body portion that extends distally from a body proximal portion to a body distal portion. A head portion extends distally from the body distal portion. A first prong that extends distally from a first prong proximal section that has a first thickness to a first prong distal section that has a second thickness that is less than the first thickness. A second prong that extends distally from a second prong proximal section that has a third thickness to a second prong distal section that has a fourth thickness that is less than the third thickness. The second prong is spaced apart from the first prong to define a gap therebetween that is configured to receive the fastener.

A method for erecting a wind turbine tower is disclosed. A tower section (8) comprising a lower flange (9) and an upper flange (10), and a plurality of stud bolts (6) and nuts (7) are provided. The tower section (8) is oriented in an upright position with the lower flange (9) below the upper flange (10), and stud bolts (6) are positioned in bolt holes (12) in the lower flange (9) with nuts (7) arranged on an upper side of the lower flange (9). The tower section (8) is lifted to a mounting position on top of another tower section (13), and a flange combination is formed by aligning the bolt holes (12) formed in the lower flange (9) of the tower section (8) with bolt holes (15) formed in an upper flange (14) of the other tower section (13), while advancing the stud bolts (6) through the bolt holes (12, 15). The invention further provides a socket tool (16) for screwing nuts (7) onto stud bolts (6) in a manner which positions the stud bolts (6) correctly with respect to a flange (9).

The invention relates to a robot for tightening bolt nuts on a vehicle chassis, the robot comprising a polyarticulated arm at the end of which is a nut tightening tool. A sleeve-shaped centering member is fixed around the nut tightening tool and comprises a frustoconical surface which makes it possible, on contact with a nut, to reposition the nut tightening tool automatically in the axis of the nut.

A screw tensioning device for tensioning or loosing tensionable screw connections comprises a fixation element to be connected to a screw, a support element moveable relative to the fixation element. The support element is arranged moveable relative to the fixation element to apply tension to or remove tension from the screw. A piston is positioned and movable within the fixation element. A volume containing a hydraulic fluid is defined at least partly by the piston, the fixation element or the support element. The movement of the piston manipulates the volume and thereby moves the fixation element with respect to the support element.

A system for installing multiple fasteners to a substrate comprising; a chassis having a frame and a transverse member; a plurality of fastener heads mounted to the transverse member; a fastener feed system; a fastener head actuator to move two or more fastener heads in simultaneous movement; and a control system having a processor configured to control movement of the fastener head actuator.

A method of operating a fastening apparatus includes: a fastening apparatus preparing step of preparing a fastening apparatus including n fastening tools; a first workpiece disposing step of disposing a first workpiece having m fastening holes at one side of the fastening apparatus; a first fastening tool disposing step of disposing each of the n fastening tools above any one of the m fastening holes; and a first storage step of storing, in a control unit, positions of the n fastening tools in the first fastening tool disposing step, in which m is larger than n, and a plurality of first fastening tool disposing steps and a plurality of first storage steps are alternately performed.

A fastening system including a frame, a movement control assembly, a fastener drive assembly and a collar presenting assembly. The frame can be coupled to an outside structure, for example, with a part that is to be coupled with a fastener attached to the frame. The movement control assembly is configured to controllably move the fastener drive assembly relative to the frame and the part so as to grasp the collar of the fastener, engage the threaded pin of the fastener and to threadedly engage the two structures together. The collar presenting assembly presents a collar of a fastener to the fastener drive assembly.
