PROBLEM TO BE SOLVED: To provide an endless sling readily formable in a short time even in the case of a long inner perimeter or a large diameter, having high flexibility and good operation efficiency in cargo hanging operation, difficult to afford a preform such as deformation into a flat state or bending and having a long life. SOLUTION: The endless sling is formed as follows. A temporary core rope is formed into a loop state and a wire rope is wound around the temporary core rope while being twisted together and turned a prescribed number of times. A part of the temporary core rope is then cut off and the residual part of the wire rope instead is inserted as a rope core while taking out the temporary core rope. COPYRIGHT: (C)2007,JPO&INPIT
