Manual lubrication of wire ropes via the drip, brush, spatula or rubber glove method has always been a difficult and time consuming maintenance task. Typically messy asphaltic or “blackjack” type products are employed which have coating abilities but very little lubrication or penetration properties – the core of the rope is therefore not lubricated. The GREASE SAFE Wire Rope Lubricator eliminates the slow and labor intensive task of manual lubrication and provides fast and effective one pass lubrication of wire ropes from 5/16″ (8mm) to 2-5/8″ (67mm) in diameter at speeds up to 3,333 feet (1,000 meters) per hour. At the same time achieving more thorough results by forcing lubricant under high pressure right through to the core of the wire rope. The result is a fully lubricated wire rope with a smooth minimal film of lubricant on the outer strands and lubricant forced through to the inner strands expelling water and other matter in the process.
