• 摩擦板 312706031 (Friction Plate): Friction plates are used in various parts of the excavator, such as the swing motor or travel motor, to create friction for braking or power transmission. They are crucial for the controlled movement and operation of the machine.

• 斗杆铲斗联接轴座带轴承（服务用） 312706210 (Arm Bucket Linkage Shaft Seat with Bearing (Service Use)): This component connects the arm to the bucket, allowing for the bucket's rotation and digging action. The inclusion of bearings ensures smooth and efficient operation. It's a critical part for excavating and material handling.

• Ⅱ主线束 312706211 (II Main Wiring Harness): The main wiring harness is the central nervous system of the excavator, connecting all the electrical components. This "II" series main wiring harness ensures proper electrical communication and power distribution within the machine.

• 斗杆铲斗联接轴座（含型套服务用） 312706213 (Arm Bucket Linkage Shaft Seat (Including Bushing for Service Use)): Similar to the previous linkage component, this connects the arm and bucket. The inclusion of bushings ensures proper alignment and reduces wear during operation.

• 右侧上封板 312706217 (Right Upper Cover Plate): This cover plate provides protection to internal components on the upper right side of the XCMG excavator. It helps to prevent damage from dust, debris, and other external factors.

Applications and Usage Scenarios:

These XCMG excavator parts are essential for maintaining and repairing a wide range of XCMG excavator models. XCMG excavators are widely used in various industries, including:

• Construction: Excavating foundations, digging trenches, lifting and moving materials, site preparation.

• Mining: Extracting minerals and ores, loading trucks, site development in mining operations.

• Infrastructure Development: Building roads, bridges, tunnels, and other essential infrastructure projects.

• Demolition: Tearing down buildings and other structures safely and efficiently.

• Landscaping: Shaping land, creating drainage systems, and other landscaping tasks.

• Agriculture: Digging irrigation ditches, preparing land for planting, and other agricultural applications.

• Forestry: Logging operations, clearing land, and building forestry roads.

For example, an XCMG XE215 excavator, which might utilize the Ⅴ动臂总成 312706017 and Ⅴ斗杆总成 312706026, is commonly seen on construction sites excavating for building foundations. Similarly, an XCMG XE370, a larger model, might use a variation of the 吸油钢管 312706015 and operate in a mining environment, loading heavy materials into dump trucks. The 摩擦板 312706031 ensures the smooth operation of the swing mechanism in both these models, allowing them to rotate and access different work areas.
