Caterpillar has released its newest development for underground loader buckets, the Durilock lip shroud system.

TAM100720 Cat DurilockThe bucket system, which is fully integrated, can be installed without a hammer and offers maintenance-free retention of GET with Cat Infinitite elastomer compression retainers. 

There are three shroud styles which are interchangeable, permitting a mine to remove one quickly and replace it with another that is ideally suited for a particular application – and all without switching out the retention system or the base edge. In fact, Durilock allows for installation and removal in half the time versus legacy, mechanically attached systems.

Specifically, the Durilock system’s styles include the D50S Standard, a traditional wedge shape used in most production and development applications; the D50A Abrasion, with a contoured design and power to reposition more material on the shroud base; and the D50P Penetration, which has less leading-edge material to deliver easier penetration in dense material.

Additionally, because bolt re-torqueing isn’t needed, Cat said GET maintenance time is also reduced by 50% and the release’s integral corner guards extend bucket in-service time by about 30%.

The Durilock Shroud System is available for Cat R1700 to R3000 loaders and most buckets with a capacity of 5 to 10 cubic metres.
