When you need to pick up large, heavy objects, grab bucketfuls of debris or demolish a building, get a tighter grip on productivity with AMI’s Graptor Bucket. Powered by a helical actuator, the Graptor Bucket features incredible holding strength. The built-in rotary actuated thumb gives operators improved flexibility and precision by maintaining constant grip on the load throughout the bucket’s entire rotation. Neatly integrated into the top crossbar of the Graptor, the actuator produces up to 54,000 foot-pounds of holding strength at 3,000 psi – putting out the most torque in the most compact design - making the Graptor a powerful tool that keeps a tight handle on heavy, bulky loads.
