Frequent Inspection
On trolleys in continuous service, frequent inspection should be
made at the beginning of each shift. In addition, visual inspections
should be conducted during regular service for any damage or
evidence of malfunction.
1. OPERATION. Operate the trolley so that it travels 3 feet
(1 metre). During the 3 feet (1 metre) of travel, check for
visual signs or abnormal noises which could indicate a
problem. Check for smooth operation. Do not operate the
trolley until all problems have been corrected.
Periodic Inspection
Frequency of periodic inspection depends on the severity of usage:
NORMAL HEAVY SEVERE
yearly semiannually quarterly
Disassembly may be required for HEAVY or SEVERE usage.
Keep accumulative written records of periodic inspections to
provide a basis for continuing evaluation. Inspect all the items in
“Frequent Inspection.” Also inspect the following:
1. FASTENERS. Check retainer rings and nuts. Replace if
missing or damaged and tighten if loose.
2. ALL COMPONENTS. Inspect for wear, damage, distortion,
deformation and cleanliness. If external evidence indicates
the need, disassemble. Check shafts, wheels, bearings and
side plates. Replace worn or damaged parts. Clean and
reassemble.
3. SUPPORTING STRUCTURE. Check for distortion, wear
and continued ability to support load.
4. TROLLEY. Check that the trolley wheels track the beam
properly and total clearance between each wheel and beam
equals 1/16 to 1/8 in. (1.6 to 3.2 mm). Check side plates for
spreading due to bending. Replace as necessary.
5. LABELS. Check for presence and legibility. Replace if
necessary.
MAINTENANCE
WARNING
• Never perform maintenance on the trolley while it is
supporting a load.
• After performing any maintenance on the trolley, test trolley,
as described in the “OPERATION” section, before returning
trolley to service.
Trolley wheel bearings are sealed and require no lubrication. If
trolley wheel rotation is rough or noisy, replace trolley wheel
bearing.
Threaded components on this trolley are metric. Verify and match
thread sizes before assembly.
Trolley Wheel Removal
1. Remove retainer ring (10) from side plate stud.
2. Remove wheel (1) and wheel bearing (4).
3. Remove retainer ring (5) and bearing (4) from wheel (1).
Trolley Wheel Assembly
1. Install new wheel bearing (4) in wheel (1) and secure with
retainer ring (5).
2. Place wheel on side plate stud.
3. Install retainer ring (10) on side plate stud.
4. Check wheel for smooth and quiet operation.
5. Check operation of trolley according to the instructions in the
“INSPECTION” and “OPERATION” sections.
Hand Chain Adjustment or Replacement
• When cutting the weld side of a hand chain link, do not cut or
nick the opposite side. A damaged link must be replaced to
prevent premature failure. A falling hand chain can injure
personnel.
NOTICE
• Proper use, inspections and maintenance will increase the life
and usefulness of your Ingersoll
Rand equipment. During
assembly lubricate gears, nuts, bolts and all machined threads
with applicable lubricants. Use of antiseize compound and/or
thread lubricant on capscrew and nut threaded areas prevents
corrosion and allows for ease of disassembly of component.
1. To create a “C” link, cut the welded side of the link with a
hack saw. Clamp one side of the “C” link in a vise and bend it
open by using pliers to grip the exposed part of the link.
2. If you are replacing the hand chain, disconnect it at the “C”
link and carefully remove the hand chain.
