1. The socket should be smooth and flat, and there should be no cracks, flaws, sharp edges and uneven surface roughness that damage the wire rope. The tip of the loop should fit freely and shorten the tip to half the depth of the groove.

2. The surface of the socket should be hot-dip galvanized, and the surface should be smooth and flat, and there should be no defects such as missing plating, zinc particles, bubbles, cracks, etc. The galvanized layer should have sufficient adhesion strength during normal application.

3. The material of the socket can be A3 steel or 15,35 high-quality carbon steel.

4. The safety load of the loop should not be less than 32% of the minimum breaking force of the wire rope.

5. When in use, the selection of the socket should be consistent with the specifications of the wire rope (Attached Table 5), and the diameter of the shaft pin used should not be less than twice the diameter of the wire rope.
