Functions of the Excavator Dipper Link (Qianqiu Jia)

• Connection and Support: The dipper link (I-beam frame) is a key connecting component between the excavator's bucket, boom, and arm. It plays a role in supporting and connecting, ensuring a stable connection among the bucket, boom, and arm, allowing the excavator's digging actions to proceed in a coordinated and smooth manner.
• Force Transmission: During excavator operations, it can transmit various forces generated during the digging process, such as digging resistance and lifting force, ensuring the effective transmission of forces between components, thereby achieving efficient digging operations.
• Maintaining Structural Stability: It maintains the structural stability of the excavator's front working device, preventing component deformation or damage caused by une

  Material of Excavator Dipper Arm Frame
• It usually adopts high-strength alloy structural steel, such as Q345, Q460 and other series of steel. This type of steel has high strength, toughness and wear resistance, and can withstand the huge stress and wear during the excavator's digging operations.
• Some high-end dipper arm frames used in special working conditions will also be locally reinforced with wear-resistant alloy materials. For example, high manganese steel or wear-resistant surfacing materials are used in easily worn parts to further improve their wear resistance and extend their service life.
• ven forces during digging operations, and extending the service life of the front working device.
