Progressive Linkage Hydraulic Thumb for 40,000 to 46,000 pound excavators.
Progressive linkage type thumbs allow for greater range of motion while maintaining grip on objects by mirroring the linkage on the bucket. These thumbs also allow the cylinder to remain closer to the stick during movement reducing potential harm to the cylinder rod, and retract more fully to be out of the way when not in use.
We offer plate mount thumbs, main pin thumbs, and progressive link thumbs for excavator operating weights ranging from 8,000 pounds to 46,000 pounds. Each thumb is designed for a specific weight range of machine and can be purchased as a hydraulic or manual configuration. Thumb tines are made from AR400 steel and built for rigorous use.
