The invention provides a system configured to adjust a jaw gripping force of a pulling head. A locking nut is threadedly attached to the pulling head and defines an aperture which extends therethrough. A frame adaptor is at least partially positioned within the aperture of the locking nut. The frame adaptor further receives a portion of the pulling head and a piston of a power tool within an aperture thereof, with the portion and the piston engaging one another within the aperture of the frame adaptor. The portion of the pulling head is operatively associated with a jaw of the pulling head. An adjustment nut is threadedly attached to the frame adaptor. Rotation of the adjustment nut, with the locking nut in an unlocked position, causes the jaw gripping force of the pulling head to either be strengthened or weakened, depending on the direction of rotation.

Jaw grip force adjustment system for offset and 90 degree pulling heads

A pulling head that can be used with a wide range of fasteners and power tools having different stroke lengths and/or power ratings. The pulling head has a set of internal jaws which has serrations that are configured to grip a wide range of fastener types and sizes. The effective stroke of the pulling head is determined by the power tool to which it is engaged, rather than by the structure and design of the pulling head. The pulling head preferably has two jaws and a jaw follower with a leading surface which provides two beveled surfaces. As a result, the trailing surface of the jaws need not be conical, thereby providing that the jaws need not be machined after they are cast, thereby providing a very low cost manufacturing solution.
