Caterpillar unveiled the Cat Durilock Shroud System for Cat R1700 to R3000 loaders and most buckets of 5- to 10-m3 capacity. It features hammerless installation and maintenance-free retention of GET with Cat Infinite elastomer compression retainers. Shroud styles can be changed quickly to match an application without changing the base edge or retention system.

The Durilock system is offered in three styles. The D50S Standard is a traditional wedge shape. The D50A Abrasion has a contoured design. The D50P Penetration has less leading-edge material for better penetration.

Compared to that of predecessor competition: installation and removal of GET is 50% faster; maintenance time for GET is reduced by 50%; and internal corner guards extend bucket in-service time by 30%, Caterpillar reported. The integral corner design boosts corner life by 15% and improves penetration compared to systems with corner rounding.
