Additionally, a detailed inspection of the winch line must be performed as described in Section 7.2.4 (for wire rope winch
lines), or 7.2.5 (for synthetic rope winch lines) and the results recorded on the Winch Line Inspection Log sheet.
IMPORTANT: Be sure to review any previous inspection records to be aware of existing winch line concerns and to allow for
re-inspection of any potential problem areas. Cumulative findings may lead to the need for winch line replacement when
looked at together.
7.2.3 SNAP HOOK INSPECTION
Inspect the condition of the Overload Indicator on the snap hook as outlined in Section 7.1.3. A winch which has been
overloaded MUST BE removed from service and returned to a factory authorized service center for repair.
Inspect the condition of the snap hook (Figure 6a) for any mechanical damage, bent, missing, or corroded parts. Any winch
with a damaged snap hook MUST BE removed from service and sent to a factory authorized service center for repair.
Check the function of the locking mechanism for free operation, and make sure that the gate cannot be opened without
first depressing the keeper. Lubricate the mechanism with light oil as instructed in Section 8.2.3. If the locking mechanism
does not operate freely after lubrication, the winch MUST BE removed from service and sent to a factory authorized service
center for repair.
Ensure that the swivel rotates freely and lubricate with light oil as instructed in Section 8.2.3. If the swivel does not operate
freely after lubrication, the winch MUST BE removed from service and sent to a factory authorized service center for repair.
Inspect the thimble, ferrules, and winch line forming the eye holding the snap hook for any wear, cuts, fraying, broken
wires, or other damage. If there is any damage to the connecting hardware, or there is any winch line damage adjacent to
the eye, the winch MUST BE removed from service and sent to a factory authorized service center for repair.
7.2.4 WIRE ROPE WINCH LINE INSPECTION
If the winch you are inspecting is equipped with a wire rope winch line, inspect the wire rope as follows and document the
findings in the Rope Inspection Log.
