To match the unique structure of Komatsu PC200 connecting rods, we've developed custom assembly fixtures. During component assembly, positioning pins and clamping devices deliver precise fixation-eliminating the position deviation common in manual assembly and boosting both product geometric accuracy and assembly compatibility.

The product's core material is Q345B steel plate, a low-alloy high-strength structural steel with a yield strength of no less than 345MPa. It offers excellent toughness and fatigue resistance, handling frequent load impacts and fluctuations in excavator operating conditions to ensure the connecting rod's long-term durability at the material level.

We hold ISO9001 quality management system certification and have built a full-process quality control system spanning incoming raw materials, production processes, and finished product shipment. Every step-from compositional and mechanical property testing of Q345B steel plates, to in-process self-inspection and mutual checks, to 3D coordinate measurement and non-destructive flaw detection for finished products-adheres to our internal inspection standards. Each connecting rod undergoes multiple rounds of rigorous testing before shipment, guaranteeing 100% qualified products for customers.
