PERIODIC INSPECTION
Periodic inspections are to be performed by a qualified designated
person. Inspection intervals vary by class of service. For Class D
Service crane, they are to be performed annually at a minimum.
Frequency of this inspection may have to be increased based on
the severity of the duty cycle and environmental conditions the
crane is subjected to. A written, dated and signed inspection report
shall be provided and maintained on file. All worn, damaged or
malfunctioning parts are to be repaired or replaced to maintain a
SAFE operational crane. Refer to the typical Inspection Schedule
and Maintenance Report found elsewhere in this manual.
Items to be inspected include but are not limited to:
1. All functional operating mechanisms for
misadjustment interfering with crane operation.
2. Operating parts for excessive wear.
3. All safety devices for malfunction.
4. All connections and mountings for loose bolts, nuts
and other fasteners for tightness.
5. All structural members and welds for deformation,
cracks or corrosion.
6. All electrical apparatus, including control contactors,
limit switches, push button stations for signs of
pitted contact points, wear or deterioration.
7. All hoists and trolleys installed on the crane in accordance
with the manufacturer’s recommendation.
ALWAYS LOCK MAIN SWITCH IN THE OPEN POSITION (OFF)
BEFORE INSPECTION.
NOTICE
CRANES THAT HAVE BEEN SITTING IDLE FOR SIX MONTHS
OR GREATER SHALL RECEIVE A COMPLETE PERIODIC
INSPECTION PRIOR TO ITS USE.
MAINTENANCE
GENERAL
Maintenance services required on top running cranes are, for the
most part, simple periodic inspections and adjustments. Procedures
for lubrication, routine adjustments and replacement of parts, if
required, are described in the following paragraphs.
LUBRICATION
AXLE BEARINGS
Axle bearings on the 7.9" (200 mm) and 10.2" (260 mm) diameter
wheels require periodical lubrication. To access grease fittings,
remove the rail sweep. Fitting is located on the pilot diameter of
each bearing cage, four total per endtruck as shown in figures 3
& 4. Lubricate with NLGI #2 General Purpose Grease, every three
months. Replace rail sweep upon completion. Using a torque
wrench, tighten all bolts to 72 ft. lbs. torque for all size end trucks.
Frequency of and type of lubrication used may be adjusted based
the severity of the duty cycle and operating environment.
