as described in this subrule and Appendix B.  
Page 20  
(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.

R 408.11873 Operational tests.  
Rule 1873. (1) Before a new or modified crane is put into operation or if a crane has not  
been used in the past 12 months, the equipment shall be tested by a designated person to  
ensure compliance with this standard, including all of the following functions:  
(a) Hoisting and lowering.  
(b) Trolley travel.  
(c) Bridge travel.  
(d) Travel limiting devices.  
(e) Locking, limiting, and indicating devices, if provided.  
(2) The trip setting of a hoist limit switch shall be determined with an empty hook  
traveling in increasing speeds up to the maximum speed. The actuating mechanism of the  
limit switch shall be located so that it will trip the switch, under all conditions, in time to  
prevent contact of the hook or hook block with any part of the trolley.  
(3) When a crane is given a load test, the test load shall be not more than 125% of the  
rated load. The test reports shall be maintained on a file within the premises where the  
crane is located.  
History: 2002 AACS; 2005 AACS; 2018 AACS.  
R 408.11874 Rated load test.  
Rule 1874. Before initial use, all new, extensively repaired, and altered cranes shall be  
tested and inspected by or under the direction of a designated or authorized person and a  
written report which confirms the load rating of the crane shall be furnished by the person.  
The load rating shall not be more than 80% of the maximum load sustained during the test.  
Test loads shall not be more than 125% of the rated load, unless otherwise recommended  
by the manufacturer. The test reports shall be placed on file where readily available to  
appointed personnel.  
History: 2002 AACS.

R 408.11875 Maintenance.  
Rule 1875. (1) An employer shall maintain a crane and its accessories in a condition that  
will not endanger an operator or other employee. A preventative maintenance program  
shall be established and the program shall be based on the manufacturer's recommendations  
and for the application as reviewed by a qualified person.  
(2) An unsafe condition on a crane determined by an inspection shall be corrected by a  
designated trained employee or a qualified crane service company before the crane is put  
into operation. Designated repair personnel shall have a thorough background in either  
mechanical or electrical operating systems, or both, and shall also have a permit to operate  
the type of crane that is being serviced.  
(3) Before adjustments or repairs are commenced on a crane, all of the following  
precautions shall be taken:  
(a) A crane to be repaired shall be moved to a location where it will cause the least  
interference with other moving equipment on the track or rails and operations in the area.  
(b) Controllers shall be placed in the "off" position.  
(c) The main switch shall be placed in the "off" or "open" position and locked out, except  
where power is necessary to adjust or service the crane.  
(d) A warning sign or "out of order" sign shall be placed at the operator control station.  
(e) Illumination of not less than 15 footcandles intensity shall be provided while  
maintenance is performed on a crane.  
(4) If any other crane uses the same runway, then a protective device shall be used to  
prevent interference with the idle crane undergoing repairs. If the protective device is  
impracticable, then a signal person shall be placed at a visual vantage point to warn the  
operator of the active crane when it reaches the limit of safe distance from the idle crane.  
(5) A crane that has been adjusted or repaired shall not be returned to normal operation  
until all guards have been replaced, locks removed by those who installed them, or their  
supervisor, safety devices reactivated, and the maintenance equipment removed.  
(6) Manual lubrication on a crane shall comply with subrule (3)(c) of this rule.  
(7) An accumulation of dirt on a crane that would create a hazardous condition shall be  
removed.
