Performance characteristics:
Equipped with Caterpillar C9 ACERT ™ The engine power reaches up to 193kW, with high output power, high combustion efficiency, and abundant power, which can enable the excavator to operate stably in complex working conditions, providing strong excavation and bulldozing capabilities. It adopts advanced hydraulic system, with more stable flow and pressure output, and can quickly and accurately control various working devices, improving work efficiency and reducing energy consumption.
Adopting high-strength materials and advanced welding technology, the whole machine structure is sturdy and durable, equipped with a hard material excavation device, and has excellent wear resistance. After strict quality control and experimental verification, it has high reliability, long service life, and can maintain stable working performance in various harsh working environments. The mechanical structure is simple, easy to maintain, and daily maintenance can be completed in a short period of time, which can reduce downtime and improve work efficiency. The oil system is equipped with filters and oil bath offline high-efficiency filters, which can extend the service life of hydraulic oil and reduce maintenance frequency

System inspection items and requirements
1. Appearance and structural inspection requirements:
Check the large and small arms for any welding or cracks (signs of refurbishment)
2. Engine system inspection requirements: Engine exhaust, no abnormal noise, no blue smoke, no carbon buildup in the exhaust pipe, no oil leakage in the oil pan, and no noise during idle.
3. Hydraulic system inspection requirements: The hydraulic pump/motor should have no vibration, cracks, or oil leakage, pressure stability, the chrome plating layer of the oil cylinder should have no scratches or oil leakage, the operation should be smooth, and the pipeline should be confirmed to have no bulges or aging.
4. Electrical system inspection requirements: The computer board should display speed, pressure, and fault codes normally.
Line: The lighting, air conditioning, and alarm system are functioning properly.
5. Inspection requirements for walking system:
Track: The rubber layer has no cracks, the chain rail has slight wear, and the chain number is consistent with the machine
Motor: When walking, the speed on both sides is consistent, and the walking is normal
