Boom Crane Grease

Importance of speciality greases for telescopic boom cranes

Formulated with ester as base oil, Berulub PAL 1 is highly viscous and extremely adhesive. The additive package includes the optimum combination of antioxidant additives, anti-wear and anti-corrosion additives.

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.

High performance greases for telescopic boom crane

Berulub PAL 1

Berulub PAL 1 is a high performance synthetic adhesive grease that is designed and recommended for heavy duty telescopic boom cranes.

Formulated with ester as base oil, Berulub PAL 1 is highly viscous and extremely adhesive. The additive package includes the optimum combination of antioxidant additives, anti-wear and anti-corrosion additives. Berulub PAL 1 also has a high dose of PTFE (Polytetrafluoroethylene) that provides continuous film for extended duration and thereby longer service life.

Recommended by Terex, Grove and Liebherr, Berulub PAL 1 is the preferred global choice of lubricant for telescopic tubes of heavy duty cranes.

Also recommended for lubrication and sealing of stop cocks, labyrinth seals, stuffing boxes and gland packings of applications in large kitchens. Also suitable for lubrication of threaded spindles in thermostat valves.
