Cat® Skeleton Buckets Feature Heavy Duty Construction and Design Elements Facilitating Efficient Separation of Rock and Debris from Soil

Used primarily to separate rocks and large debris from soil and sand, Cat® Skeleton Buckets feature heavy duty construction and find application in a number of industries, including agriculture, construction, land clearing, demolition, landscaping, and scrap handling. Designed for use with skid steer loaders, multi-terrain loaders, compact track loaders, and compact wheel loaders, Cat Skeleton Buckets incorporate a number of structural elements that ensure efficient operation and long-term durability.

In basic construction, Cat Skeleton Buckets use heavy steel rods, 1.25 inches (31.75 mm) in diameter on 3.75-inch (95-mm) centers, to form the floor and back of the bucket. Thick plates with rectangular openings form the sides of the bucket, and a rectangular frame, fabricated of heavy duty steel and incorporating two steel plate rock dams, strengthens the back of the bucket. The rock dams serve to retain material, reducing spillage and increasing production.

For added durability, steel gussets are welded between the outermost rods in the bucket floor and the sides of the bucket. The forward ends of the rods in the bucket floor are secured in a heavy-duty support beam positioned between (and welded to) the bucket sides. This beam not only provides support, but allows the bucket to also be used for grading.  Welded to the forward tips of the rods and support beam are heavy steel tines that enhance breakout force by initially separating rock and debris from soil more effectively than could a solid cutting edge.
