3.
AIR SYSTEM. Visually inspect all connections, fittings, hoses and components for indication of air leaks. Repair any leaks or damage. Check
and clean filters if equipped.
4.
CONTROLS. During operation of winch, verify response to control is quick and smooth. If winch responds slowly or movement is
unsatisfactory, do not operate winch until all problems have been corrected.
5.
BRAKES. During winch operation test brakes. Brakes must hold load without slipping. Automatic brakes must release when winch motor
throttle is operated. If brakes do not hold load, or do not release properly, the brakes must be adjusted or repaired.
6.
WIRE ROPE REEVING. Check reeving and ensure wire rope is properly secured to the drum.
7.
LUBRICATION. Refer to the "LUBRICATION" section for recommended procedures and lubricants.
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 items listed in "Frequent Inspection." Also inspect the following:
1.
FRAMES and UPRIGHTS. Check for deformed, cracked or corroded main components. If external evidence indicates the need for additional
inspection return winch to your nearest Ingersoll-Rand service repair center.
2.
FASTENERS. Check retainer rings, split pins, capscrews, nuts, and other fasteners on winch, including mounting bolts. Replace if missing
or damaged and tighten if loose.
3.
DRUM AND SHEAVES. Check for cracks, wear or damage. Replace if necessary.
4.
WIRE ROPE. In addition to Frequent Inspection requirements, also inspect for the following:
a.
Build-up of dirt and corrosion. Clean with steam or a stiff wire brush to remove dirt and corrosion if necessary.
b.
Loose or damaged end connection. Replace if loose or damaged.
c.
Check wire rope anchor is secure in drum.
d.
Verify wire rope diameter. Measure the diameter of the wire rope from crown-to-crown throughout the life of the wire rope. Recording
of the actual diameter should only be done with the wire rope under equivalent loading and in the same operating section as accomplished
during previous inspections. If the actual diameter of the wire rope has decreased more than 0.4 mm a thorough examination of the wire
rope should be conducted by an experienced inspector to determine the suitability of the wire rope to remain in service. (Refer to Dwg.
MHP0056).
5.
ALL COMPONENTS. Externally inspect for wear, damage, distortion, deformation and cleanliness. Clean, replace or lubricate components
as required.
6.
BRAKE. Test brake to ensure proper operation. Brake must hold a 125% rated load with full drum without slipping. If indicated by poor
operation or visual damage, return winch to a authorized service center for repair. Check all brake surfaces for wear, deformation or foreign
deposits. If brake lining thickness appears to be worn , contaminated or damaged brake band should be replaced. Clean and replace components
as necessary.
7.
FOUNDATION OR SUPPORTING STRUCTURE. Check for distortion, wear and continued ability to support winch and rated load. Ensure
winch is firmly mounted and that fasteners are in good condition and tight.
8.
LABELS AND TAGS. Check for presence and legibility of labels. Replace if damaged or missing.
Winches Not in Regular Use
1.
Equipment which has been idle for a period of one month or more, but less than six months, shall be given an inspection conforming to the
requirements of "Frequent Inspection" before being placed in service.
2.
Equipment which has been idle for a period of over six months shall be given a complete inspection conforming with the requirements of
"Periodic Inspection" before being place in service.
3.
Standby equipment shall be inspected at least semi-annually in accordance with the requirements of "Frequent Inspection". In abnormal
operating conditions equipment should be inspected at shorter intervals.
