Hydraulic Thumb for Excavator
The Hydraulic Thumb enhances your excavator's versatility. It grips and moves objects with precision, boosting productivity on diverse job sites. We offer two installation options. Choose between main pin mounting or welded attachment to suit your excavator setup. Our thumbs come in two link types. The direct link offers 140 degrees of movement, while the progressive link exceeds 180 degrees. This attachment features a strong hydraulic cylinder with a double-acting check valve. It ensures reliable operation and safety in various conditions. The thumb's optimal shape fits many bucket styles and widths. Its serrated teeth provide a firm grip on different materials. Designed for durability, it includes grease points on pivot points. The thumb retracts neatly against the dipper stick when not in use. Ready to boost your excavator's capabilities?
