Component Specifications

Definition
Side cutters, also known as cheek plates, are hardened steel components mounted on the lateral edges of mining bucket lips. They serve dual functions: providing sharp cutting edges for penetrating tough materials like rock and ore, and acting as protective shields that absorb abrasion and impact forces to preserve the structural integrity of the bucket body. These components are strategically positioned to optimize material flow and reduce wear on adjacent bucket sections.
Working Principle
Side cutters operate on the principle of concentrated force application through hardened cutting edges to fracture and separate materials during excavation. Cheek plates function as sacrificial wear surfaces that distribute mechanical stresses and prevent direct abrasion on the bucket's main structure. Together, they create an efficient cutting envelope while extending bucket service life through controlled wear patterns.
Materials
High-alloy abrasion-resistant steel (AR400-AR500 grades), heat-treated for optimal hardness (400-500 HB) and toughness. Common specifications include: ASTM A514, JIS G3106 SB450, or equivalent wear-resistant steel plates with minimum yield strength of 450 MPa.

  • Hardness 400-500 HB
  • Thickness 25-75 mm
  • Mounting Pattern Bolt-on or welded
  • Cutting Edge Length 300-1500 mm
Standards
ISO 13333, DIN 22211
