Automatic Drum Brake (optional feature)
The automatic drum brake is a spring applied, air released, externally mounted brake which utilizes an air actuated, spring loaded cylinder to
automatically disengage the brake when the motor is operated. Air pressure in the cylinder overcomes spring pressure to release the brake.
When the control valve is placed in the neutral position, the air in the cylinder is vented allowing spring tension to automatically engage the
brake and prevent drum rotation. The cylinder clevis must be kept properly adjusted to hold the required load.
Manual Drum Brake (optional feature)
The manual drum brake operation is the same as described in 'Automatic Drum Brake' section with the exception that the brake is manually
engaged and released by an operator manually shifting the brake handle.
• All new, altered or modified equipment should be inspected and tested by personnel instructed in safety, operation and
maintenance of this equipment to ensure safe operation at rated specifications before placing equipment in service.
• Never use a winch that inspection indicates is damaged.
Frequent and periodic inspections should be performed on equipment in regular service. Frequent inspections are visual examinations
performed by operators or service personnel during routine winch operation. Periodic inspections are thorough inspections performed by
personnel trained in inspection of the winch. Inspection intervals depend upon the nature of the critical components of the equipment and the
severity of usage. Careful inspection on a regular basis will reveal potentially dangerous conditions while still in the early stages, allowing
corrective action to be taken before the condition becomes dangerous.
Deficiencies revealed through inspection, or noted during operation, must be reported to an appointed person. A determination must be made
as to whether a deficiency constitutes a safety hazard before resuming operation of the winch.
Records and Reports
Some form of inspection record should be maintained for each winch, listing all points requiring periodic inspection. A written report should
be made monthly on the condition of the critical parts of each winch. These reports should be dated, signed by the person who performed the
inspection, and kept on file where they are readily available for review.
Wire Rope Reports
Records should be maintained as part of a long-range wire rope inspection program. Records should include the condition of wire rope
removed from service. Accurate records will establish a relationship between visual observations noted during frequent inspections and the
actual condition of wire rope as determined by periodic inspections.
Frequent Inspection
On equipment in continuous service, frequent inspection should be made by operators at the beginning of each shift. In addition, visual
inspections should be conducted during regular operation for indications of damage or evidence of malfunction (such as abnormal noises).
1.
WINCH. Prior to operation, visually inspect winch housings, controls, brakes and drum for indications of damage. Do not operate the
winch unless the wire rope feeds onto the drum smoothly. Any discrepancies noted must be reviewed and inspected further by authorized
personnel instructed in the operation, safety and maintenance of this winch.
2.
WIRE ROPE. Visually inspect all wire rope which can be expected to be in use during the day's operations. Inspect for wear and damage
indicated by distortion of wire rope such as kinking, "birdcaging," core protrusion, main strand displacement, corrosion, broken or cut
strands. If damage is evident, do not operate winch until the discrepancies have been reviewed and inspected further by personnel
instructed in the operation, safety and maintenance of this winch.
• The full extent of wire rope wear cannot be determined by visual inspection. At any indication of wear inspect the wire rope in
accordance with instructions in "Periodic Inspection."
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 if the lever sticks,
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 by an authorized
service repair center.
6.
WIRE ROPE REEVING. Check reeving and ensure wire rope is properly secured to the drum. Do not operate the winch unless the wire
rope feeds onto the drum smoothly.
7.
LUBRICATION. Refer to the "LUBRICATION" section for recommended procedures and lubricants.
8.
PENDANT (optional feature). Ensure pendant operation is smooth and that winch is responsive to pendant control. Check that pendant
buttons return when pushed and released.
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.
