Graptor Bucket

The AMI Attachments Graptor Bucket is the only integrated thumb bucket powered by a helical actuator, producing up to 54,000 foot-pounds of torque at 3000 PSI. Holding strength like this maintains constant grip on the load throughout the bucket’s entire rotation. This makes the Graptor Bucket perfect for handling large, heavy objects or grabbing bucketfuls of debris. Starting with AMI’s Heavy Duty Digging Bucket made with Hardox and Strenx structural steel, aggressive serrated sidebars are added or choose optional bolt-on side cutters. US patents 10,774,498 and 10,774,501.

Product Features

Helical Actuator

Designed for strength and durability, the Jawbone is powered using a helical actuator fitted into the crossbar. With holding strength up to 54,000 ft.lbs of torque at 3,000 PSI, the actuator's tidy design eliminates the need for bulky hydraulic cylinders.

Constant Grip

Confidently handle heavy and awkward loads with the superior grip of the Graptor's integrated thumb. For demolition work requiring picking, sorting and transferring, the Graptor strongly grips the load and holds it securely throughout the full rotation of the bucket, all the way to roll out. The Graptor also takes out the guesswork of trying to control both thumb and bucket at the same time, providing a safer worksite and reducing hydraulic line failure from over-pressure.

Heavy Duty Construction

Aggressive serrated side bars, welded in place come standard for maximum grip. Replaceable side cutters are available for more abrasive applications. The Graptor is built using low wearing Hardox 450 steel.
