Product Description

Excavator Thumb 

Hydraulic Type/Mechanical Type/ Progressive Type

Thumb was designed for excavator and loader. No matter mechanical thumb or hydraulic thumb, weld-on or bolt-on type. We can customize thumb

built with the existing bucket, the thumb tine spacing is set to mesh perfectly with the teeth on the bucket. Thumb and bucket rotate around the same pin. Pins made by us, are for long wear life.

NEW DESIGN-Progressive Thumb
Keep the pressure on productivity with LIGONG Progressive Link Hydraulic Thumb attachment for excavators. Designed to provide constant pressure throughout the entire cylinder range, the Progressive Link Thumb achieves more than 180 degree rotation to easily reach and pick up objects close to your excavator. The extra linkage expands the thumb's reach across the bucket's entire rotation - including at full roll-out - to deliver superior material handling in the harshest conditions.

1.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.

2.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.

The advantage of Ligong's Hydraulic Pin-On Excavator Thumbs overHydraulic Weld-On Thumbs is a more effective range of motion andoptimal grip because the thumb always follows the tip radius of thebucket. This would be a good option for heavy use operators.
