Belzona® Brings Excavator Back To Service In 1 Day



Mining and Quarrying (MINQ)



Mechanical Power Transmission (MPT)


Customer Location:

Salt mine, Germany.


Application Date:

November 2009


Application Situation:

Excavator shovel at salt mine



The severe conditions of corrosion and abrasion in the mine caused loss of metal in the articulated coupling, which resulted in reduced service life of the component.



Belzona 1821 (Fluid Metal)





Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet MPT-2. Belzona 1821 was injected into former to create required shaft diameter.


Belzona Facts:

The complete removal of the coupling for its replacement would have taken time and money, since the support plates would have needed to be stripped down. The Belzona molding technique offered on site repair solution taking only 1 day to be completed. This significantly extended the service life of the coupling and allowed production to continue with minimal downtime.
