Jawbone Bucket Powered by RAMCAM™

When multi-tasking is a must, the AMI Attachments Jawbone 4-in-1 Excavator Bucket Powered by RAMCAM™ responds with a multipurpose design that digs, grades, grips and clamshells. The RAMCAM™ technology works using hydraulic cylinders which are fully enclosed and fully protected from the elements. At first glance, the AMI Jawbone Powered by RAMCAM™ looks no different than a regular digging bucket, however enclosed along the back are two hydraulic cylinders. This provides all the power of a hydraulic thumb but without the custom installation. With as much holding power and gripping strength as a thumb, the AMI Jawbone 4-in-1 Excavator Bucket Powered by RAMCAM™ 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 Powered by RAMCAM™ also works as a clamshell bucket for loading and dumping straight down. Patent Pending.


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 Hydraulic Cylinders

Ingeniously designed, the RAMCAM™ drivetrain efficiently transfers energy from standard hydraulic cylinders, 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.
