5.3 Jib bending and deformation (1 mm = 3.93701 × 10-2 in)

Check for bending of the whole jib a ≤ 8.5 a ≤ 1.5 + L /1000

No significant bending in vertical and horizontal direction shall be found.

L = 7000 (jib full retraction)

IWY01-001007

Check for dents and other localized indentation or bending d ≤ 0.8 (for indentations with L ≥ 15 mm)

IWY01-0010E08

5.4 Wire rope (1 mm = 3.93701 × 10-2 in)

Criteria for wire rope replacement

1. Replace the wire rope if it is deformed or corroded.

2. Replace the wire rope if it is kink ed.

3. Replace the wire rope if 10% or more of the wires (except for filler wires) in a lay are broken.

4. Replace the wire rope if the diameter is reduced by more than 7% of the nominal diameter.

5. Replace the wire rope if it has been degraded by heat.
