Anchor Windlass
An anchor windlass is a machine (winch) that restrains and manipulates the anchor chain or rope on a vessel, allowing the anchor to be raised or lowered. Technically speaking the term “windlass” refers only to horizontal winches. Ver6cal designs are called capstans.Horizontal windlasses make use of an integral gearbox and motor assebly, with a horizontal shaP through the unit and wheels for chain and/or rope on either side.
Sha=’s fric?on bearing Lubrica?on -‐ Common Prac?ces
Common prac6ces involved in the lubrica6on of the fric6on bearings in windlasses are to use commercial heavy duty general purpose marine greases and to usually relubricate prior every use of the system. For tanker vessels this is usually been done at least two-‐four 6mes per month. Due to heavy shock loads and water contamina6on, lubricant starva6on, wear, rust & oxida6on are common problems, as seen in the pics below (housing opened aPer 6 months, lubricated at least twice per month, with a heavy duty commercial grease)

Almagard® 3752 -‐ Performance results
Almagard® 3752 is a heavy duty smooth and extremely tacky lithium complex grease, that stays put, will not wash off (fully waterproof), pound out or melt and run even in severe condi6ons. It will greatly extend relubrica6on intervals, reducing grease consump6on, wear and maintenance costs. Product shock load performance can be viewd in LE’s “moustrap demo”.
Almagard® 3752 has been tested in tanker’s anchor windlass systems with great performance results. In more detailed, shaP’s fric6on bearings were opened aPer 6 months of opera6on, having been lubricated only one 6me, during the first applica6on. As seen in the following photos, lubricant remained in place, providing a constant lubrica6on film in both the shaP & the housing. There is not any abnormal wear detected or rust and oxida6on as seen in the same housing with the commercial lubricants. Since relubrica6on frequency reduced from at least 12-‐32 6mes in 6 moths to just one ini6al applica6on, grease consump6on has been greatly reduced.

Cost Jus?fica?on -‐ Cost effec?veness
Although Almagard® 3752 costs more in a Kg per Kg comparison with commercial greases, the reduc6on of grease consump6on alone cost jus6fies the choise, reducing the cost needed for purchasing grease. Of great importance is of course the maintenance cost benefits, deriving by its performance results, reducing the cost needed for the maintenance of the windlasses.

Cost Jus?fica?on -‐ Cost effec?veness -‐ Case Study No 2
Following pictures shows windlasses’ shaPs & covers aPer 6 months of use, without any relubrica6on. Almost all grease remained in place and no lubricant starva6on observed.
Relubrica6on with previous lubricant took place once a week.
