Second-hand Komatsu PC400-8 Advantages

1. High cost performance

Price advantage: The second-hand price is usually only 30%-50% of the new machine, which is suitable for users with limited funds or short-term project needs.

Stable value retention rate: Komatsu brand second-hand equipment has strong liquidity and low subsequent resale loss.

2. Durable core components

Engine: Equipped with Komatsu SAA6D114E-3 engine, the electronic fuel injection technology is fuel-efficient and powerful (net power is about 199kW), with a long design life and can last for more than 20,000 hours without major repairs if properly maintained.

Hydraulic system: Komatsu's self-developed CLSS hydraulic system has precise operation and smooth compound movements, suitable for heavy-duty operations (such as mining and earthwork).

3. Controllable maintenance costs

Wide supply of spare parts: large domestic stock, abundant aftermarket parts, and reduced maintenance costs.

Simple structure: Compared with new models, PC400-8 has a moderate degree of electronicization, and mechanical failures are easier to troubleshoot (such as no complex sensors).

4. Strong adaptability

Excellent performance in mining/earthwork: Standard reinforced chassis and bucket, suitable for high-intensity operations; optional accessories such as breaker and grabber.

Good stability: Wide track design (optional 600mm/800mm) reduces ground pressure and is not easy to sink in soft soil conditions.

5. User reputation

Low failure rate: Generally reported hydraulic oil leakage and travel failures are less than those of competitors of the same generation (such as Carter 330D).

Fuel consumption economy: The average fuel consumption is about 18-22L/hour (depending on the working conditions), which is better than some domestic second-hand machines of the same tonnage.

Notes (Must Read)

Inspection Focus: It is recommended to focus on engine smoke color, abnormal sound of hydraulic pump, oil leakage of rotary motor, and cracks of crawler frame when inspecting the machine.

Reference hours: preferably within 10,000 hours, and overhaul records need to be evaluated for more than 15,000 hours.

Emission restrictions: National III emission standards, it is necessary to confirm whether local policies allow use.
