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
