These buckets are designed to work principally in mining and quarry industries, with either straight or spade edges. The straight edge has higher breakout force and increased dump clearance; the spade edge offers better penetration.

Cat® Heavy Duty Rock Bucket Highlights

  • Designed for quarry and mining applications where maximum abrasion resistance is required.
  • Ideal choice for loading cold slag or shot granite.
  • Pre-drilled to accept segments and sidebar protectors.

High Strength Steel

Matched to the application and material, high-strength steel is used for greater durability.

Increased Tire Life

Extra wide buckets can increase tire life, meaning reduced operating costs.

Wear Strips & Liner Plates

Added wear strips reduce the need for costly bucket rebuilds. Some bucket designs feature wear-resistant liner plates, which permit easier rebuilding when needed.

Variable Capacities

Bucket capacities are determined by material density.

Accepts Cat GET

Proper selection of cutting edges and teeth will increase productivity while lowering ground engaging tool (GET) costs. These buckets are offered with or without teeth, with teeth and bolt-on segments, or with bolt-on cutting edges. The larger loaders also offer side bar protectors, and the Caterpillar MAA (mechanically attached adapter) System and MAWPS (mechanically attached wear plates system) in place of standard bolt-on and weld-on wear plates.
