In 2001, a quarry site commissioned a new material handling installation featuring two large stackers. Each machine included numerous moving components such as conveyor drum bearings, rollers, and pivot shafts. Altogether, each stacker required lubrication at 84 different points. Given the scale and mechanical complexity, establishing a reliable and efficient lubrication system from the start was essential for long-term performance and maintenance efficiency.
MEMOLUB HPS
Rimelig automatisk smøring for 84 kritiske stablelager.
Context
Problem
While a centralized dual-line lubrication system was initially considered, budget limitations quickly ruled it out. The cost per lubrication point exceeded €250, making it financially unviable for the project. Manual lubrication was also deemed impractical due to the number of points, their locations, and the frequent servicing required. Relying on manual greasing would have made maintenance labor-intensive, inefficient, and difficult to standardize across machines.
Solution
To meet both technical and budgetary needs, the site adopted MEMOLUB HPS automatic lubricators. Each stacker was equipped with 18 systems in total—16 GIGA and 2 MEGA units—configured in a mix of single-point and progressive distributor setups depending on the application. The lubricators were filled with LT 2 lubricant and programmed for reliable, consistent delivery to all required points without technician intervention.
Resultater
MEMOLUB-løsningen muliggjorde en fullt automatisert smøreprosess til en betydelig redusert kostnad. Den totale installasjonskostnaden ble under 100 euro per smørepunkt – mer enn 60 % lavere enn det sentraliserte alternativet med to linjer. Systemet sikret regelmessig og nøyaktig smøring av alle komponenter, eliminerte behovet for manuell smøring og gjorde at det nye utstyret kunne operere med økt pålitelighet og lavere vedlikeholdskrav.
