While performing a pre-use check, the operator must check the wire rope system for all of the following EXCEPT?

When conducting a pre-use check of a crane's wire rope system, the operator's primary focus is on the integrity and condition of the wire rope itself as well as its associated components. The selection that indicates the size and grade of the wire rope is not typically included in pre-use checks, as it is typically established during the initial installation and selection phase.

Excessive corrosion, damage of any kind, and proper sheave movement directly affect the safety and functionality of the crane during operation. Corrosion can weaken the wire rope, compromising its load-bearing capacity. Any signs of damage can indicate potential failure points, making it critical to assess these factors in regular inspections. Proper sheave movement ensures that the wire rope travels smoothly without undue friction or wear, which is essential for maintaining the effective operation of the lifting system. Thus, while size and grade are significant for the selection and specification of wire rope, they fall outside the scope of the daily pre-use checks that assess ongoing operational safety and functionality.
