The choice of wire rope

According to the use of wire rope, the following principles should be followed:

(1) General lifting luffing rope: preferred to use 6-wire contact wire rope;

(2) Tensioning ropes and traction ropes for cranes: priority is given to the use of winding ropes;

(3) Support ropes for cable cranes or aerial ropeways: single ropes are preferred;

(4) Giving priority to galvanized steel wire ropes when working in corrosive environments;

(5) When working in an acid-resistant environment, lead-plated wire ropes are preferred;

(6) Cranes working in high temperature environments should use steel cords with extraordinarily ductile asbestos core wire ropes or steel cores;

(7) Lift ropes should be made of 8 strands of wire rope with resilience as special grade;

(8) A port crane or tower crane with a lifting ratio of 1/1 shall use 18 strands of non-rotating wire rope;

(9) The electric hoist hoisting rope is preferred to use point-contact wire strands of 37 wires each;

(10) Tether cords are preferred to use less stringent Class II cords.
