Mobil Wire Rope Dressing

Mobil Grease, Canada


Product Description

Wire Rope Dressing is manufactured from high quality petroleum base stocks, carefully blended with selected soaps and additives. It is designed as a field dressing for drum hoist ropes and is equally recommended for rope lubrication on shovels and drag lines.

Features and Potential Benefits

Wire Rope Dressing is field tested in day-to-day service at operating mines demonstrated outstanding performance even in the most demanding service.


At ambient temperatures between -40 °C and +50 °C, wire ropes are protected by a tenacious film that adheres firmly to the rope. Fling-off and sling-off are virtually eliminated so lubricant consumption and housekeeping concerns are minimized. Wire Rope Dressing is formulated using non-asphaltic base stocks which minimize peeling, cracking and flaking off in cold weather. The formulation is also designed to ensure complete coverage of the rope while preventing excessive lubricant buildup.


Wire Rope Dressing is formulated using mineral base oils blended with molybdenum disulfide and solid graphite lubricant. Crown wires retain a tough, cohesive lubricant film even after passing over the sheave and idler wheels or the hoist drum. The cohesive nature of Wire Rope Dressing also contributes to reduced fling off and sling off while in service.

Corrosion Resistance

Unique additive packages included in the Wire Rope Dressing formulation protect wire ropes from rust and metal corrosion.

Water Resistance

Wire Rope Dressing offers exceptional water resistance. Moderate amounts of water can be absorbed by the grease with little or no change in NLGI penetration. In field tests, the majority of shaft water seen was in the form of beads on the surface of the lubricant.


Wire Rope Dressing is recommended for application either by split-box, pressurized canister or spray method onto hoist drum wire ropes in underground mining, dragline or electro-mechanical shovel operations. Always protect Wire Rope Dressing from contamination with dust.
