INSPECTION, TESTING AND MAINTENANCE
GENERAL
INSPECTION CLASSIFICATION
1. Initial inspection. Prior to initial use, all new,
altered, modified or extensively repaired cranes
shall be inspected by a designated person to
insure compliance with provisions of this
standard.
2. Regular inspection. Inspection procedure for
cranes in regular service is divided into two
general classifications based upon the intervals
at which inspection should be performed. The
intervals in turn are dependent upon the nature
of the components of the crane and the degree
of their exposure to wear, deterioration, or
malfunction. The two general classifications are
herein designated as "frequent" and "periodic"
with respective intervals between inspections
as defined below.
A. frequent inspection - daily to monthly intervals
B. periodic inspection - one to twelve intervals or
as specifically recommended by the
manufacturer
FREQUENT INSPECTION
3. Inspection shall be performed by designated
personnel.
A. control mechanisms for maladjustment
interfering with proper operation - daily, when
used
B. control mechanisms for excessive wear of
components and contamination by lubricants or
other foreign matter
C. safety devices for malfunction
D. all hydraulic hoses, particularly those which flex
in normal operation of crane functions, should
be visually inspected once every working day,
when used
E. hooks and latches for deformation, chemical
damage, cracks, and wear. Refer to
ANSI/ASME B30.10
F. rope reeving for compliance with crane
manufacturer's specifications, if optional winch
is used
G. electrical apparatus for malfunctioning, signs of
excessive deterioration, dirt and moisture
accumulation
H. hydraulic system for proper oil level and leaks
daily
I. tires for recommended inflation pressure, cuts
and loose wheel nuts
J. connecting pins and locking device for wear and
damage
PERIODIC INSPECTION
4. Deformed, cracked or corroded members in the
crane structure and carrier
5. Loose bolts, particularly mounting bolts.
6. Cracked or worn sheaves and drums.
7. Worn, cracked, or distorted parts such as pins,
bearings, shafts, gears, rollers and devices.
8. Excessive wear on brake and clutch system
parts and lining.
9. Crane hooks inspected for cracks.
10. Travel steering, braking, and locking devices,
for malfunction.
11. Excessively worn or damaged tires.
12. Hydraulic and pneumatic hose, fittings, and
tubing inspection.
A. evidence of leakage at the surface of the
flexible hose or its junction with metal and
coupling
B. A. blistering, or abnormal deformation to the
outer covering of the hydraulic or pneumatic
hose
C. A. leakage at threaded or clamped joints that
cannot be eliminated by normal tightening or
recommended procedures
D. A. evidence or excessive abrasion or scrubbing
on the outer surface of a hose, rigid tube, or
fitting. Means shall be taken to eliminate the
interference of elements in contact or otherwise
protect the components
