Thumb for CAT/Caterpillar backhoes

Gentec Equipment

Achieve any excavating and material job better and faster with our superior thumbs made for CAT/Caterpillar backhoes.

Operating a CAT backhoe requires dexterity and precision. When equipped with a thumb attachment, not only does it become easier to maneuver, it increases your handling capacity. Hydraulic thumbs for backhoes will simplify picking, holding, and moving heavy materials like pieces of concrete, rocks, debris, and trunks, and placing them precisely. When attached to a bucket, a hydraulic thumb provides an even pressure throughout the entire cylinder range. Gentec Equipment’s thumbs can reach a 130-degree rotation, which makes it easier for the backhoe to move in smaller spaces. Our excavator thumbs have 2 to 4 fingers made with robust high-strength steel plates, along with serrated edges. Each thumb is fully gusseted for improved strength. Our inventory regroups multiple sizes of thumb attachments (8” to 32” width and 24” to 72” length).

Gentec Equipment has been a hydraulic thumb manufacturer and distributor for over 15 years. We specialize in the manufacturing, sale, distribution, and service of attachments and support equipment for the civil engineering, landscaping, construction and forestry areas everywhere in Canada and the United States.
