LANDYINDUS Hydraulic Excavator Thumb | High-Strength Alloy Steel | Up to 126° Grab Angle | 16 MPa | 60 LPM | 1–9T Mini Excavator | Converts Standard Bucket into Grappling Tool | ME-HTB1, ME-HTB3 & E-HTB5
The LANDYINDUS Hydraulic Excavator Thumb is purpose-built for 1–9 ton mini excavator operators who need to convert their standard excavator bucket into a powerful, versatile grappling tool — ready to handle rocks, broken concrete, tree stumps, branches, demolition debris, and irregular salvage that a bucket alone cannot manage.
Bucket + Hydraulic Thumb = Grapple — Handle Materials a Bucket Alone Cannot
A standard excavator bucket can dig, scoop, and push — but it cannot grip, hold, and precisely place irregular materials. The hydraulic thumb closes against the bucket to create a clamping jaw action, giving the operator full control over:
- Jagged rocks and broken concrete — grip and place precisely without scattering
- Tree stumps and root balls — clamp and extract or relocate intact
- Demolition debris — sort, grip, and load irregular pieces
- Branches and timber — handle without rolling or slipping
- Irregular salvage — grip and position materials of any shape
Up to 126° Grab Angle — Maximum Versatility Across Material Shapes, Sizes and Terrain
The wide grab angle of up to 126° (E-HTB5) provides maximum versatility when handling materials of varying shapes, sizes, and weights across different terrain conditions. A wider grab angle means the thumb can open further from the bucket, allowing the operator to position the thumb over larger or more irregularly shaped materials before closing the grip.
| Model | Grab Angle | Excavator Class | Weight (kg) |
|---|---|---|---|
| ME-HTB1 | 121° | 1–2T | 22 |
| ME-HTB3 | 124° | 2.5–3.5T | 42 |
| E-HTB5 | 126° | 5–9T | 72 |
Hydraulic Thumb vs Fixed (Mechanical) Thumb — Hydraulic Control vs Manual Positioning
| Feature | Fixed / Mechanical Thumb | LANDYINDUS Hydraulic Thumb (This) |
|---|---|---|
| Thumb positioning | Manual — pin-set positions only | Hydraulic — infinite positions, cab-controlled |
| Grip adjustment | Stop machine, exit cab, repin | Continuous adjustment from cab |
| Clamping force | Fixed — depends on pin position | Variable — full hydraulic force on demand |
| Material handling speed | Slow — manual repositioning | Fast — continuous cab-operated control |
| Operator safety | Exit cab to reposition | Fully cab-operated — no ground exposure |
| Best for | Light occasional use, budget | High-cycle, mixed materials, productivity |
16 MPa | 60 LPM — Seamless Integration with Standard Mini Excavator Hydraulics
The hydraulic thumb operates at 16 MPa with a hydraulic flow requirement of 60 LPM, ensuring smooth and responsive performance that integrates seamlessly with most standard excavator hydraulic systems. The 60 LPM flow requirement is within the standard auxiliary hydraulic output range of most 1–9T mini excavators — verify your machine’s auxiliary hydraulic output before ordering.
High-Strength Alloy Steel — Precision Welding, Weld-On Bracket, Long Service Life
Fabricated from high-strength alloy steel with precision welding throughout, the E-HTB series delivers outstanding resistance to wear, impact, and corrosion — reducing downtime and keeping long-term maintenance costs low. The robust weld-on bracket design ensures a secure, stable fit that holds up under continuous heavy-duty use.
