Hydraulic Thumb for CAT, Komatsu, XCMG, LiuGong and Other Excavators
TOOSAN hydraulic thumbs can be matched with many common excavator brands, including CAT, Komatsu, Hitachi, SANY, XCMG, LiuGong, Volvo, Hyundai, Doosan, JCB, Kobelco, Kubota and other excavators.
A hydraulic thumb works together with the excavator bucket to grab, hold and move rocks, logs, concrete blocks, scrap, branches and demolition debris. It is commonly used in land clearing, demolition cleanup, road construction, forestry work, farm maintenance and general earthmoving projects.
The suitable hydraulic thumb model depends on the excavator weight, bucket width, hydraulic flow, operating pressure, arm structure and mounting dimensions. Different excavator brands and models may have different pin sizes, arm widths and bucket structures, so the hydraulic thumb should be matched correctly before shipment.
TOOSAN hydraulic thumbs are aftermarket excavator attachments. Brand names are used only for excavator compatibility reference. TOOSAN is not affiliated with CAT, Komatsu, Hitachi, SANY, XCMG, LiuGong, Volvo, Hyundai, Doosan, JCB, Kobelco or Kubota.
Key Features
A practical hydraulic thumb should help the excavator bucket grab materials more securely. It is especially useful when the bucket alone cannot hold irregular materials during lifting, moving or sorting work.
TOOSAN focuses on practical matching before shipment. We help customers check excavator size, bucket width, hydraulic requirements and mounting position before recommending a suitable hydraulic thumb.

Hydraulic Thumb Matching Guide
Choosing the right hydraulic thumb depends on the excavator weight, bucket width, hydraulic flow, operating pressure, arm structure and mounting position.
A thumb that is too small may not hold materials effectively. A thumb that is too large may affect operation, installation or bucket movement. Before recommending a model, TOOSAN checks the excavator size, bucket size and real working application.
Common excavator matching range:
– 1–3 ton excavator: small hydraulic thumb for landscaping, light cleanup and small material handling
– 4–8 ton excavator: compact thumb for rocks, branches, logs and light demolition debris
– 10–15 ton excavator: medium hydraulic thumb for construction cleanup and general material handling
– 18–25 ton excavator: heavy-duty thumb for larger rocks, logs, concrete blocks and demolition work
– 30 ton and above: large thumb for heavy material handling and special applications
