1.6w (19) is a Valentin type steel wire rope. 6 round strands, 19 steel wires per strand.

2.Φ13.5 is the nominal diameter of the steel wire rope, the unit is millimeters

3.155 refers to the nominal tensile strength, the unit is kilogram force/mm2. Equivalent to the 1570MPa level in the current standard.

4. Smooth steel wire rope

5. Right cross, which means that the twisting method is right cross twisting. The more commonly used twisting method.

6 The minimum breaking tension of this kind of steel wire rope is 94.4KN (hemp core steel wire rope) or 101.8KN (steel core steel wire rope).

In other words, when the safety factor is 4, a single wire rope can lift 2.4t (hemp core wire rope) or 2.6t (steel core wire rope).
