Application Date:

May, 2007

 
 

Application Situation:

Tire of a dump truck

 
 

Problem:

One of the tires of the dump truck had two lateral cuts, which reached the metal mesh and may have been caused by stone impact during movement. It was necessary to repair the affected area in order to prevent the cut from expanding and the tire to become useless before the end of its useful life. Lateral cuts measured 130 mm and 500 mm in length and 40 and 60 mm in depth.

Substrate:

Rubber

 
 

Application Method:

The application was conducted according to Belzona Know-How System Leaflet SHM-9. The lateral cut was opened and all the loose rubber was removed, reaching the inner liners, without exacerbating the problem. After scarification of the rubber, cleaning of the cut and application of Belzona 2911 conditioner, two repairs were made: the first one with the application of Belzona 2311 and the second one with the application of Belzona 2211.
