✅ Detailed Description
The CAT D7 bulldozer series combines durability, power, and precision for demanding construction and mining tasks. Powered by the C9 ACERT turbocharged diesel engine with 275HP (194 kW), the D7 delivers exceptional pushing force and reliable fuel efficiency. As a result, operators can complete heavy earthmoving projects faster while maintaining consistent performance across long-term operations.
Designed for versatility, these crawler bulldozers feature semi-universal (SU) blades that support precise cutting, dozing, and material spreading. The robust undercarriage and wide 560 mm tracks enhance traction and stability, even on uneven or loose terrain. In addition, the LS-type transmission ensures smooth, responsive operation both forward (10.54 km/h) and in reverse (13.58 km/h), improving workflow efficiency.
Operator comfort is a priority. The spacious cabin offers excellent visibility, ergonomic controls, and reliable instrumentation, reducing fatigue during long working hours. Moreover, the bulldozer complies with Tier II / Stage II emission standards, combining environmental responsibility with high performance.
Consequently, whether deployed for mining support, road foundation work, or large-scale land clearing, the CAT D7 series bulldozers provide durable, cost-effective solutions. Their proven reliability, strong lifting and pushing capacity, and versatile blade options make them a trusted choice for global construction and earthmoving operations.
