INSPECTION, TESTING AND MAINTENANCE
GENERAL
22. Test loads shall not exceed 110% of the
manufacturer's load ratings.
23. Written reports shall be maintained showing
test procedures and confirming the adequacy
of repairs.
MAINTENANCE
PREVENTIVE MAINTENANCE
24. Before adjustment and repairs are started on a
crane, the following precautions shall be taken
as applicable:
A. crane placed where it will cause the least
interference with other equipment or
operations
B. all controls at the "off" position
C. starting means rendered inoperative
D. boom lowered to the ground if possible or
otherwise secured against dropping
E. relieve hydraulic oil pressure from all hydraulic
circuits before loosening or removing hydraulic
components
25. Warning or "OUT OF ORDER" signs shall be
placed on the crane controls.
26. After adjustments and repairs have been made,
the crane shall not be returned to service until
all guards have been reinstalled, trapped air
removed from hydraulic system (if required),
safety devices reactivated, and maintenance
equipment removed.
ADJUSTMENTS AND REPAIRS
27. Any hazardous conditions disclosed by the
inspection requirements shall be corrected
before operation of crane is resumed,
Adjustments and repairs shall be done only by
designated personnel.
28. Adjustments shall be maintained to assure
correct functioning of components, The
following are examples:
A. functional operating mechanism
B. safety devices
C. control systems
29. Repairs or replacements shall be provided as
needed for operation.
The following are examples:
A. critical parts of functional operating
mechanisms which are cracked, broken,
corroded, bent, or excessively worn
B. critical parts of the crane structure which are
cracked, bent, broken, or excessively corroded
C. crane hooks showing cracks, damage, or
corrosion shall be taken out of service. Repairs
by welding are not recommended
30. Instructions shall be provided by the
manufacturer for the removal of air from
hydraulic circuits.
LUBRICATION
All moving parts of the crane, for which
lubrication is specified, should be regularly
lubricated per the manufacturer's
recommendations and procedures.
ROPE INSPECTION
31. Frequent Inspection
A. All running ropes in service should be visually
inspected once each working day. A visual
inspection shall consist of observation of all
rope which can be in use during the days
operations. These visual observations should
be considered with discovering gross damage
such as listed below, which may be an
immediate hazard.
1. distortion of the rope such as kinking,
crushing, un-stranding, birdcaging, main
strand displacement, or core protrusion.
Loss of rope diameter in a short length or
unevenness of outer strands should be
replaced
2. general corrosion
3. broken or cut strands;
4. number, distribution and type of visible
broken wires. When such damage is
discovered, the rope shall either be
removed from service or given as
inspection.
