Komatsu D155-2 Bulldozer Core Advantages Analysis
Komatsu D155-2 is a classic model among medium-sized bulldozers, featuring high cost performance and reliability and durability, suitable for earthwork, mine stripping and agricultural land consolidation. The following are its core advantages:

1. Powerful power and excellent fuel economy
✅ Komatsu SAA6D140E-5 engine (354 horsepower/264kW)

Mechanical fuel injection system, simple maintenance, suitable for low-quality diesel.

Low speed and high torque design, fuel consumption is 5-8% lower than that of the same level models.

✅ Torque converter + power shift gearbox

3 speed forward/3 speed reverse, to meet different working conditions.

Automatic downshift protection to prevent engine overload.

2. Strong structure, mine-level durability
🛡️ Strengthened chassis design

Box-section crawler frame, high torsional strength, suitable for heavy-duty operations.

Heavy-duty final drive (gear life 15,000 hours+).

⚙️ High wear-resistant configuration

Optional mining kit (including Hardox 450 material blade).

Sealed and lubricated track to reduce sand and stone intrusion and extend life.

3. Simple operation and convenient maintenance
📊 Mechanical instrument panel + fault warning system

Real-time monitoring of key parameters (oil temperature, oil pressure, water temperature).

Fault code display for quick troubleshooting.

🛠️ Maintenance convenience

Centralized lubrication system (reduces daily maintenance time).

Ground maintenance (oil and hydraulic filter are easy to replace).

4. Wide range of applicable scenarios
🚜 Typical operation scenarios

Earthwork (roadbed, reservoir construction).

Mine stripping (with U-shaped blade, high efficiency).

Agricultural land consolidation (wetland, farmland bulldozing).
