Each of the bucket-like rakes has tines on the floor to allow dirt and small material to sift through while catching large material. Hydraulically operated dual, independent grapple assemblies clamp and hold irregularly shaped materials when carrying and truck loading.
The two rakes are 72 inches and 84 inches wide. High clamping force, large vertical jaw opening and heavy-duty design make the rakes productive and durable. Reinforced and gusseted tines ensure durability in tough applications. The smaller rake has nine tines and the larger one has 11.
The grapples open vertically to 37 inches to grab large objects, and clamping force is 2,250 pounds per grapple. Balanced and synchronized hydraulics ensure smooth independent or synchronized grapple clamping while preventing drift. The grapples have grease zerks and hardened and chromed hinge and cylinder pins for reliable operation, and the grapple cylinders are protected to prevent objects from damaging them.
Specially designed protection for the machine couple—manual or hydraulic—increases reliability of the entire system, according to the manufacturer. Connect-under-pressure hydraulic fittings allow for easier connections if the tool has been sitting in the sun and building hydraulic pressure internally.
