Periodic Inspection - Ingersoll Rand MLK Serie Manual De Instalación Y Operación

7. CHAIN (ref. Dwg. MHTPA0102). Examine each of the
links for bending, cracks in weld areas or shoulders, traverse
nicks and gouges, weld splatter, corrosion pits, striation
(minute parallel lines) and chain wear, including bearing
surfaces between chain links. Replace a chain that fails any
of the inspections. Check chain lubrication and lubricate if
necessary. See "Load Chain" under "LUBRICATION."
•
The full extent of chain wear cannot be determined by visual inspection. At any indication
of chain wear inspect chain and load sheave in accordance with instructions in "Periodic
Inspection."
•
A worn load chain may cause damage to the load sheave.
8. LOAD CHAIN REEVING. Make sure welds on standing links are away from the powered chain
sheave. Reinstall chain if necessary. Make sure chain is not capsized, twisted or kinked. Adjust
as required.

Periodic Inspection

Frequency of periodic inspection primarily depends on the severity of usage:
NORMAL
yearly
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 rivets, capscrews, nuts, cotter pins and other fasteners on hooks, hoist
body and chain bucket, if used. Replace if missing and tighten or secure if loose.
2. ALL COMPONENTS. Inspect for wear, damage, distortion, deformation and cleanliness. If
external evidence indicates the need for additional inspection return hoist to your nearest
Ingersoll-Rand service repair center.
3. HOOKS. Inspect hooks for cracks. Use magnetic particle or dye penetrate to check for cracks.
Inspect hook retaining parts. Tighten or repair, if necessary.
4. LOAD CHAIN WHEELS. Check for damage or excessive wear. Replace damaged parts.
Observe the action of the load chain feeding through the hoist. Do not operate a hoist unless the
load chain feeds through the hoist and hook block smoothly and without audible clicking or
other evidence of binding or malfunctioning.
5. MOTOR. If performance is poor, contact your nearest service repair center for repair
information.
6. BRAKE. Raise a load equal to the rated capacity of the hoist a few cms (inches) off the floor.
Verify hoist holds the oad without drift. If drift occurs, contact your nearest service repair center
for repair information.
7. SUPPORTING STRUCTURE. If a permanent structure is used inspect for continued ability to
support load.
8. TROLLEY (if equipped). Refer to manufacturers instructions for installation and service
information.
9. LABELS AND TAGS. Check for presence and legibility. Replace if necessary.
