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 Graptor® 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, awkward loads with the superior grip of the Graptor® Bucket Powered by RAMCAM™. For demolition work, the Graptor® strongly grips the load and holds it securely throughout the full rotation of the bucket, all the way to roll out.


Maximized Gripping Strength

With the increased force at mid-stroke of the hydraulic cylinders, RAMCAM™ provides more grip of heavy objects.


Hardox® 500 Tuf Outer Shell

The outer shell is comprised of Hardox® 500TUF wear plate for ultimate wear protection that eliminates the need for heavy wear bars.


Increased Crushing Force

Providing greater torque, RAMCAM™ delivers up to 84% more crushing force than the previous Graptor®, for more ripping, biting and demolishing that's reliable and durable.


Grease Bank

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


Heavy Duty Construction

Aggressive serrated side bars, made using Hardox® 450 wear plate are welded in place provide extra grip.
