Compact Jawbone Bucket Powered by RAMCAM™

When multi-tasking is a must, the AMI Attachments Jawbone 4-in-1 Excavator Bucket responds with a multi-purpose design that digs, grades, grips and clamshells. At first glance, the AMI Jawbone excavator bucket looks no different than a regular digging bucket, however inside the crossbar is a powerful hydraulic rotary actuator. This provides all the power of a hydraulic cylinder-style thumb but without custom installation. With as much holding power and gripping strength as a thumb, the AMI Jawbone 4-in-1 Excavator Bucket handles logs, rocks and scrap easily. You can also switch between digging and ditching with the ability of two different cutting edges on one bucket. Now you can dig and grade without costing you downtime changing buckets. For swampy material handling, the AMI Jawbone Excavator Bucket also works as a clamshell bucket for loading and dumping straight down.


RAMCAM™ Technology

RAMCAM™ is a revolutionary new drivetrain that allows for mechanical rotation using hydraulic cylinders enclosed within a protective casing. Patent Pending.


Fully Enclosed Single Hydraulic Cylinder

Ingeniously designed, the RAMCAM™ drivetrain efficiently transfers energy from standard hydraulic cylinder, through a splined camshaft and into the Jawbone thumb for a tight grip on every load. And with RAMCAM™ completely enclosed, all components are fully protected at all times.


Constant Grip

Confidently handle heavy and awkward loads with the superior grip of the Jawbone's integrated thumb. For demolition work requiring picking, sorting and transferring, the Jawbone strongly grips the load and holds it securely throughout the full rotation of the bucket, all the way to roll out. The Jawbone 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 plates come standard for maximum grip. The Jawbone is built using Hardox 450 steel.


Grease Bank

With all the grease points now protected, the Jawbone powered by RAMCAM™ features a grease bank for simple and routine maintenance.
