Application Situation
The customer was losing $1200 USD per day by not being able to operate this trailer. This belt design incorporates an attached chain on either side of the belt, so replacing the belt would require a lengthy process of disassembling quite a bit of the trailer just to get to the belt, plus the cost of replacement. In the past, other alternatives such as stitching had not proved successful.
Application Method
All loose rubber was removed, and an area on either side of the tear had the top layer of the belt delaminated to accommodate the Belzona 2211 application and not interfere with the scraper. The exposed surface was cleaned and roughened using a grinder and stiff wire wheel leaving the exposed fabric and rubber rough. The Belzona 2911 QD conditioner was applied and allowed to dry as per the IFU before the Belzona 2211 and Belzona 9341 reinforcement sheet was applied. The duct tape was placed around the edges to achieve a clean application, and was removed as soon as the material was applied.
Belzona Facts
Only one 550 gm unit of Belzona 2211 was used leaving the customer an extra one for any future applications. The application was completed in roughly two hours, and the trailer will be able to return to service within the following 36 hours. Alternative repair options would have left the trailer unusable for at least a week or more, and the labor time for the alternative repair options would have been well over a hundred hours instead of only two. The savings from using Belzona on an application of this nature are huge.
