Study of Holding Power of Wire Rope Clips in a Wire Rope Loop,

摘要

This report presents the results of tests performed on 3/8, 1/2, and 5/8 inch independent wire rope core (IWRC) wire rope, and 3/8, 1/2, and 5/8 inch fiber core wire rope. The test samples consisted of end-over-end wire rope loops held together with various numbers of clips. A 50,000 pound capacity tension tester was used to apply forces to a loop of wire rope that was affixed between a stake pocket and a shackle. The tension tester was used to apply a force to the wire rope loop until a predetermined displacement occurred between the wire ropes at the connection or until the wire rope broke. Instrumentation was used to measure the force into the wire rope loop, displacement between the wire ropes at the connection, and the displacement between the platens on the tester.
