3. On Catwalks fitted with a drive chain skate winch, inspect the drive chain for wear and possible
sprocket looseness. Ensure the chain master link is properly attached and the chain is well lubricated
and tensioned. The chain should have between 1/4” to 1/2” droop between sprockets on the slack
side.
4. Either before each tripping run or monthly, inspect the skate winch cable and drum for signs of wear.
Check for broken wire in the cable and excessive grooving in the drum.
5. Check the carrier lift winch cables for signs of wear. Check for broken wires in the cable. Ensure cables
are not crossed and are riding in the correct groove on the main winch drum.
6. Inspect the carrier lift winch motor and brake hydraulic lines for signs of wear and leaks. For detailed
information and maintenance on the carrier lift winch, refer to the Lantec
®
Manual.
