High-strength fibre rope for hoisting equipment such as cranes

A high-strength fibre rope for hoisting equipment, comprising:

• a rope core comprising high-strength synthetic fibres or strands;
• and
• a sheathing surrounding the rope core and optically indicating wear,
• wherein the sheathing comprises at least one sheath layer made up of at least two textile subunits of a first hierarchy level, which are braided with each other,
• wherein the sheathing comprises an outermost sheath layer and a further sheath layer arranged underneath the outermost sheath layer,
• wherein textile subunits of the first hierarchy level of the outermost sheath layer differ in textile structure from that of the further sheath layer, and thereby exhibit different wear resistances, and
• wherein textile subunits of a lowermost hierarchy level of the rope are not dispersed in a resin matrix in the outermost sheath layer and are not dispersed in a resin matrix in the further sheath layer arranged underneath the outermost sheath layer.
