摘要

Low weight swing bolt for heavily loaded structures, including: a main bolt or internal bolt (1) and an external bolt (2) that acts as redundant in the event of failure, a locking nut (3) that prevents the exit of the external bolt (2) once installed on the main bolt (1), a system for adjusting the length between the mooring points maintaining the orientation of the said points and controlling the longitudinal displacements by means of a regulating ring (4) ) threaded on its outside and inside with opposite threads so as to prevent the exit of the external bolt (2), characterized in that the interior of the main bolt (1) has a large diameter axial channel where one piece (6) is included whose constitution and longitudinal arrangement requires the grease lubricating the interior to flow from the injector (3) to the axial outlet channels (8) through a series of radial channels.
