Crane operations typically involve lifting and moving heavy objects and cargo with tonnage sometimes weighing beyond 1,000 tons. While such operations are carefully planned and orchestrated, the machine elements are subjected to immense stress and need to perform flawlessly and with precise synchronization. The telescopic segments that form central part of the crane absorb extreme surface pressure during actual operations. Smooth movement of these telescopic tubular segments is directly related to the health of the lubricating film on the segments.

Given that Cranes mostly operate under dusty conditions as well direct exposure to weather conditions such as humidity, rain, temperature variations, the lubricating film should remain intact even after repeated movement. Any variation or break of the film on the sliding surface would result in jerks or erratic movement of the boom. This critical interface requires special lubricants.
