The Cat D7G crawler dozer is a medium-sized engineering workhorse that excels across diverse scenarios. Boasting robust power, flexible maneuverability and durable quality, it serves as a core asset for mining operations, road construction, farmland renovation and other engineering projects.
Equipped with the Cat® 3306 DITA six-cylinder diesel engine independently developed by Caterpillar, it delivers a rated power of 150 kW and a peak power of up to 164 kW. Matched with a power shift transmission with 3 forward gears and 3 reverse gears, it features strong and responsive power output, easily handling heavy-duty tasks such as dozing, leveling, excavation and material stockpiling.
With an operating weight of 20,580 kg, the machine offers a range of blade options to suit different working conditions: the semi-U blade has a capacity of 5.75 m³, while the S-blade and A-blade have capacities of 4.2 m³ and 2.9 m³ respectively. Its crawler design ensures a large ground contact area and low ground pressure, and combined with a compact turning radius, it enables agile operation even in confined spaces or complex terrains.
The ergonomically designed cab features a spacious interior with noise and vibration reduction technology, and the adjustable seat plus clear control interface greatly reduces fatigue during long hours of operation. The engine’s modular layout and convenient ground-level service access allow for easy disassembly and replacement of key components. Supported by Caterpillar’s preventive maintenance and remanufacturing services, it significantly cuts down downtime and operation and maintenance costs.
Its high-strength steel structure has been proven in harsh working conditions, delivering low failure rates and stable operating efficiency. Backed by Caterpillar’s global unified after-sales service system, the Cat D7G stands as a rugged, reliable, hassle-free and high-efficiency partner for engineering construction projects.
