Werk-Brau’s custom designed multi-tine thumb, coupler and heavy duty trenching buckets are designed to fit on Komatsu PC27MR-3 through PC55MR-3. With Komatsu’s factory-welded thumb mounting bracket and standard auxiliary hydraulics, installation is fast and simple, according to the manufacturer.
Thumb hoses connect directly to excavator line ports for a tight no-leak, no-contamination seal. Changing buckets or to other attachments is fast and secure with Werk-Brau’s pin-lock coupler. Multiple attachment versatility keeps the machine busy with attachments such as: solid tine grapples, ditching-grading buckets, tilting ditching-grading buckets, cemetery bell-hole buckets, coral rock buckets, extra heavy duty buckets, pavement removal buckets, rotary compactors, excavating rakes, and rippers. Similar attachments also are available for models PC18MR-3 and PC88MR-8.
