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.

Lubrificazione automatica a prezzi accessibili per 84 cuscinetti critici del trasloelevatore.
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.
Risultati
La soluzione MEMOLUB ha consentito un processo di lubrificazione completamente automatizzato a un costo notevolmente ridotto. Il costo totale di installazione è stato inferiore a 100 € per punto di lubrificazione, oltre il 60% in meno rispetto all’alternativa centralizzata a doppia linea. Il sistema ha garantito una lubrificazione regolare e accurata di tutti i componenti, ha eliminato la necessità di lubrificazione manuale e ha consentito alle nuove apparecchiature di funzionare con maggiore affidabilità e minori esigenze di manutenzione.
