One of Werk-Brau’s newest offerings is the progressive linkage hydraulic thumb, which is custom built to match Werk-Brau and competitive brand couplers and buckets.
The Werk-Brau linkage design allows 180 degrees of rotation.
The universal linkage pivot system install on any excavator arm without removing dipper arm linkage, cutting the installation time in half. Increased rotation allows the thumb to match the bucket through almost 100% of its working cycle. The collapsible linkage design also allows the thumb jaw unit to close further to prevent damage to the arm while the machine is in the transport position.
A strong, rigid skeletal structure increases torsion resistance, and built-in linkage positional stops offer protection of the cylinder on both the inward and outward stroke. The thumb includes a retaining pin to prevent to prevent cylinder drift when not in use. Removal of only two pins allows the jaw unit to be removed from the machine in a matter of minutes. Mechanics all over agree that this is one of the easiest thumbs to install in the industry. This thumb will be a valuable time saving piece in your attachment arsenal.
