Bracket/Linkage Mounting Points: Bolt Hole Diameter 20-40 mm

Component Specifications

Definition

Bracket/Linkage Mounting Points are critical structural interfaces on bucket assemblies designed to connect hydraulic linkages, pins, and pivot mechanisms. These components ensure precise alignment, load distribution, and mechanical stability during excavation, lifting, and material handling operations. They are engineered to withstand dynamic forces, vibration, and environmental stresses while maintaining dimensional accuracy for optimal machine performance.

Working Principle

These mounting points function as rigid connection interfaces that transfer operational forces from hydraulic actuators through linkage systems to the bucket. They maintain geometric alignment under load, allowing controlled articulation while preventing unwanted movement or deformation through precisely machined surfaces and reinforced structural design.

Materials

High-strength alloy steel (ASTM A572 Grade 50 or equivalent), heat-treated to 35-45 HRC hardness with corrosion-resistant coatings (zinc plating or powder coating). Alternative materials include forged steel for high-impact applications or ductile iron for cost-effective solutions.
