Mich. Admin. Code 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.
