The counterweight is an important component of the excavator’s traveling mechanism, and its functions are mainly reflected in the following aspects:
1. Supporting the chassis and preventing loosening: The counterweight is fixed under the wheel frame with screws to support the weight of the machine and distribute the weight on the track shoes, thereby supporting the chassis. This design not only ensures the stability of the excavator but also prevents the tracks from loosening, ensuring that the excavator can operate stably in various working environments.
2. Preventing track derailment: The counterweight’s wheels are equipped with flanges on both sides, which can grip the track chains to prevent track derailment. This design ensures that the excavator can travel correctly along the track direction, avoiding lateral slippage of the tracks.
3. Reducing rolling resistance and improving work efficiency: The counterweight grips the track chains with its wheel flanges, preventing lateral slippage of the tracks and reducing rolling resistance when the excavator operates in muddy or watery conditions. This helps improve work efficiency and extend the machine’s lifespan.
4. Sealing and lubrication: The counterweight is equipped with floating seals and O-ring seals internally, effectively preventing lubricating oil leakage and preventing mud and water from entering the counterweight, maintaining its good working condition.
The counterweight’s multiple functions, including preventing track derailment and reducing rolling resistance, ensure the stable operation and efficient work of the excavator.
