Mich. Admin. Code R. 408.11872 - Frequent and periodic inspections

Rule 1872.

(1) Inspections shall be made as designated in this subrule and Table 3.

(a) An employer shall establish an inspection schedule based on usage and classification as described in this subrule and Appendix B.

(b) The inspection procedure for cranes in regular service is divided into 2 general classifications based upon the intervals at which inspection should be performed. The intervals in turn are dependent upon the nature of the critical components of the crane and the degree of its exposure to wear, deterioration, or malfunction. The 2 general inspection classifications are designated as frequent and periodic, with respective intervals between inspections as specified in this rule.

(c) Each crane designed and manufactured prior to January 1, 1971 shall be inspected at least monthly. The inspection schedule may be modified based on documented inspection and repair history and a qualified person's recommendations.

(2) Frequent inspection includes examinations by a designated person who makes required records, as follows:

(a) Monthly to quarterly (class C) or at intervals of 100 hours of use, whichever comes first. Frequent inspection includes observations during operation and of items listed in Table 3.

(b) A designated person shall determine whether conditions found during the inspection constitute a hazard and whether a more detailed inspection is required.

(3) Periodic inspection includes inspection of the equipment in place by a designated person who makes records as listed in Table 3 and as follows:

(a) Annually or at intervals of 500 hours of use, whichever comes first. Periodic inspections include observations during operation and of items listed in Table 3.

(b) Conditions of extreme duty cycle, heat, and corrosive or climatic extremes indicate a need for more frequent inspections before use.

(c) Cranes with multiple service classifications shall be inspected in accordance with the highest rated duty classification.

(d) A designated person shall determine whether conditions found during an inspection constitute a hazard and whether disassembly is required for additional inspections.

(4) A crane which is used in infrequent service, that is, which has been idle for a period of 1 month or more, shall be inspected before being placed in service.
