GR Series Rock Grapples are ideal for a variety of applications

Overview

• GR Series Rock Grapples are designed to be a multipurpose tool for land clearing, brush removal applications, and jobsite clean-up.

Benefits

• Each unit includes two independent-action grapples that allow for optimal clamping action when grappling objects with non-uniform sizes such as root balls, large rocks, or demolition debris.
• Open sides on the rock grapple models allow easy grappling of material that is wider than the bucket
• Specifically integrated design features allow the rock grapples to be used for grading a site after debris removal
• Tine spacing allows for material sifting when used in the forward direction
• The bucket heel profile allows for loose material to flow through or for scarifying of surfaces when grading in reverse
• A weld-in serrated cutting edge supports each tine and provides superior material penetration capabilities
• Greaseable and hardened 31.8-mm (1.25-in.) pins with increased cylinder specifications result in improved durability
• An improved hose routing over the previous series grapples eliminates the need for grapple cylinder stops on large frame G-Series Skid Steers
• Increased side cutter, side sheet, and backsheet plate thicknesses, combined with larger torque tubes result in heavy-duty bucket construction for the most demanding applications

Design improvements

Overview

• Accomplish more with increased capacity and improved design.

Benefits

New rock grapple design

• Tines are spaced three inches apart and fully supported on each side for maximum bend resistance
• Weld-in serrated cutting edge easily penetrates difficult ground conditions
• Solid backplate along the Quik-Tatch™ area protects hydraulic cylinder hoses and the machine from debris and damage
• Thickened side cutter, side sheet, and backplate combine with large torque tubes for heavy-duty construction that meets the most demanding applications

Increased cylinder size

• Cylinder size of 63.5-mm (2.5-in.) bore diameter and 35.56-mm (1.4-in.) rod diameter delivers high grapple forces to tackle even the most difficult materials
• Grapple arms feature integrated mechanical stop to reduce cylinder load when open

Improved grapple capacity

• 619.76-mm (24.4-in.) wide grapple arm and range of grapple stances  help grasp broad, cumbersome loads

• Independent-action grapples enable different-sized objects to be picked up with each grapple

Improved hose routing

• Durable 90-degree quick-couplers on the hydraulic cylinder hoses eliminate interference with the grapple
• Standard low-profile cylinder guards simplify hose connection.
