Inspect the condition of the winch line snap hook as described in Section 7.2.3, and record the results on
the Winch Inspection Log sheet.
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.
7.2.4.1 Introduction to Wire Rope Terminology
Before discussing wire rope inspection criteria you need to understand the basic construction of wire rope
and the terms used to describe it (see Figure 9). Wires (a) are the individual elements that make up a
wire rope. A number of wires are laid together to form strands (b), and then a number of strands are laid
together around the core (c) to form the wire rope (d).
