Component Specifications

Definition
The Dipper Connection is a precision-engineered structural component that forms the interface between the dipper (bucket) and the dipper handle (arm) in hydraulic excavators. It transmits digging forces, controls bucket articulation, and withstands dynamic loads during excavation cycles. This connection typically incorporates pin joints, bushings, and reinforcement plates to ensure proper load distribution and operational reliability.
Working Principle
Operates as a pivot point using hardened steel pins and bushings to allow rotational movement of the dipper relative to the dipper handle. Hydraulic cylinders attached to the connection provide controlled bucket curling and dumping actions through mechanical leverage.
Materials
High-strength alloy steel (ASTM A572 Grade 50 or equivalent), hardened steel pins (SAE 8620), bronze or polymer bushings, corrosion-resistant coatings
Technical Parameters
  • Weight 45-180 kg
  • Bushing Type Self-lubricating bronze composite
  • Pin Diameter 50-120 mm
  • Load Capacity 15-50 tons
  • Operating Temperature -40°C to 120°C
Standards
ISO 9001, ISO 10243, DIN 1480
