Abstract: A load binder for securing a load, the load binder comprising an elongated threaded contraction expansion assembly including an elongated threaded member and opposing threaded end screws, with the elongated threaded member having opposing ends with opposite screw threading, wherein the threading in the elongated threaded contraction expansion assembly is constructed and arranged to provide common contraction or extension of the respective opposing threaded screws when the elongated threaded member is rotated one direction or another and the opposing threaded screws, a driven link chain sheave, a drive shaft, a primary link chain drive sheave, an external hex drive, and a link chain movably engaged with the driven link chain sheave and the primary link chain drive sheave, wherein the external hex drive can be rotated to turn the primary link chain drive sheave to either draw the ends of the threaded screws closer together or drive them further apart.

Abstract: A load binding tool for securing a load, the load binder including an elongated threaded contraction expansion assembly including an elongated threaded member having opposing ends with opposite screw threading, and having opposing engaging ends, and enabling common contraction or extension of the respective opposing engaging ends when the elongated threaded member is rotated one direction or another, and a driven sheave, a drive shaft, a primary drive sheave, and a closed loop of chain or other flexible coupler movably engaged with the driven sheave and the primary drive sheave, wherein the drive shaft can be rotated to turn the primary drive sheave and move the opposing engaging ends closer together or further apart. The drive shaft is can be coupled with an external drive coupling that can be engaged with a separate drive tool to rotate the drive shaft and operate the load binding tool.

Abstract: Embodiments herein relate to the general art of connector links, and to the particular field of coupling links for coupling to one or more chain links. Particular embodiments include coupling links having a body with a central portion that has an aperture passing therethrough, a closed first end that is integral, and a second end that has an opening, and a retaining member in the form of a removable, deformable, or pivotable member that may selectively provide a closure to the opening. Other embodiments include retaining members on both ends of the coupling link.
