The Geith progressive linkage (pro-link) hydraulic thumb provides up to 180 degrees of rotation, allowing operators to pick up and place rocks, tree stumps and pipes — among other odd-shaped objects — closer to the excavator. The pro-link thumb’s universal pivot linkage system enables it to be installed on any excavator arm — without requiring the removal of the dipper arm linkage.
Manufactured with high-strength steel, the thumb’s strong, rigid structure and oversized high-profile pivot pin increase torsion resistance. In addition, integrated linkage positional stops protect the hydraulic cylinder from damage, while a lock-up pin enables operators to safely secure the thumb in a storage position when not in use. The induction-hardened-chrome hydraulic cylinder rod further extends the pro-link thumb’s working life.
