Stick Pivot Hydraulic Thumb
The AMI Hydraulic Stick Pivot Thumb provides great functionality to your excavator and backhoe. Stick Pivot means the thumb rotates on the same pivot point as the original bucket pin, not a secondary weld-on pivot point. The hydraulic cylinder is also directly connected to the thumb, covering 65-75% bucket rotation. Since both the thumb and the bucket rotate on the same axis, the thumb tip and bucket teeth maintain constant grip on the load when rotating. Unlike thumbs that use a secondary weld-on pivot point, the AMI Stick Pivot eliminates scraping and slippage and reduces risk of release during rotation.
Bucket Pin Rotation Point
The hydraulic cylinder is also directly connected to the thumb, covering 65-75% bucket rotation. Since both the thumb and the bucket rotate on the same axis, the thumb tip and bucket teeth maintain constant grip on the load when rotating.
Spherical Bushings
The hydraulic cylinder’s seals stay intact by allowing the thumb to naturally flex when handling awkward material without adding torsional stress to the seals.
Cushioning Cylinder
By restricting the flow of hydraulic oil at the end of the cylinder stroke, AMI thumbs retract smoothly without a hard stop. This reduces the wear and tear on the excavator and prevents machine shake, making it more comfortable for the operator.
