HLA Attachments SFRH77GR66BO500 Heavy-Duty Stone Fork with GR66 Grapple combines a 77-inch retainer-tine stone fork, a 66-inch hydraulic utility grapple and BO500 universal skid-steer-style quick-attach mounting in one robust stone and debris handling attachment. Built for demanding material-handling work, it provides the tine strength, close spacing and hydraulic clamping action needed to gather, retain and move stones, roots, brush and other irregular debris. Its grapple opens up to 70 inches, providing useful clearance for bulky loads while helping secure material during lifting and transport.
The 77-inch stone fork uses heavy-duty, retainer-style tines measuring 1-3/4 inches in diameter. Tines are spaced 2-3/4 inches apart, allowing loose material to pass between them while helping retain larger stones and debris. Each tine point is made from 3/4-inch-thick, 400 Brinell high-strength steel for durability in abrasive applications.
The underlying heavy-duty stone fork is rated for a 9,500 lb capacity. It measures 31 inches high and 50 inches deep, creating a substantial working area for collecting material. The nominal 77-inch attachment width offers broad coverage for clearing and cleanup tasks.
A 66-inch GR66 regular utility grapple adds hydraulic load control to the stone fork. The grapple opens as wide as 70 inches to accommodate bulky or irregular material and closes over the load to improve retention. It is equipped with 2-1/2 x 8-inch hydraulic cylinders.
This combination is suited to applications where an open stone fork alone may not provide enough control over brush, roots, debris or loosely stacked material. The grapple helps hold the load against the fork during handling, reducing the chance of material shifting or rolling away.
