Demolishing the norm is the powerful performance of the AMI Attachments Graptor-Integrated Thumb Bucket and Graptor-Root Rake. The Graptor gives you the advantage of a hydraulic thumb mounted to the bucket, not your excavator. Powered by a helical actuator, the Graptor provides constant grip on the load throughout the bucket's full rotation, making it ideal for demolition work. Since the thumb is part of the bucket, the Graptor makes coupling simple and removes extra weight and bulk from the end of the stick when a thumb is not required. Available for 10,000–90,000lb. excavators, the Graptor knocks down the barriers to better productivity for all applications.
