The end of a single wire rope is bent back along the rope to form the eye, and strands are hand-tucked into the body of the rope in what is called a Wallis Splice. This splice is tapered and concealed by tucking strand ends into the rope, making a sling that is easily pulled through narrow spaces; there are no rough ends to snag hands. Hand Splice Eye The Wallis Splice utilizes tension in the rope body to secure strands where they are tucked back into the rope. Needs no metal sleeve to assure firm anchoring. When “tapered and concealed”, ends of strands are tucked inward and concealed inside the rope. WARNING: Hand-spliced slings should not be used in lifts where the sling may rotate and cause the wire rope to unlay. HOW TO ORDER: For a single leg hand spliced sling with loop on each end, with rated capacity of 1.8 tons vertical, 12 ft. long. ORDER: One 1/2″ diameter type HS-1-1, 12 ft. long. RATED CAPACITY – Tons* Rope Diam Vert. Choker Hitch U

Introduction The article will focus on the significance of the ASTM-A-931 test involving the tensile testing of wire ropes and strands, the way the test is done and in which industries this test applies and also highlight issues faced by users. The types of extensometry currently used for performing the test will be discussed, concluding with how to use Imetrum’s UVX non-contact video extensometer to more accurately and efficiently carry out the test. ASTM A-931 Test and Methodology ASTM A-931 encompasses the tensile testing of steel wire strands and ropes at room temperature. The test purpose is to determine the yield strength, breaking force, modulus of elasticity and elongation. The test is done till the load drops below the maximum and at this point strands can be heard breaking. The test speed must be below 0.032mm/min for each mm of specimen length (i.e. 910mm specimen should be tested at a max speed of 28mm/min). According to the standard, determining the modulus requires spec
