Proper grease coverage on the foundation anchor bolts is essential for the longevity of the rods, nuts and washers and for maintaining proper tension on the bolts. However, we have often found that it is difficult to distribute the grease thoroughly on the rod, particularly in the minors of the threads. Greasing the rods by hand is messy and often result in injury to personnel from metal slivers.
NTC Wind Energy has developed a tool to make greasing the rods safe, quick and efficient. Simply attach the grease applicator to a drill, add about a half ounce of grease to the upper side of the rod and slowly spin the applicator down the rod and back up again. The interchangeable rollers inside the applicator provide even and complete grease coverage without leaving grease on the tower wall.
