Product Features & Advantages

Powerful & Fuel-Efficient Engine

The Cat 306D is powered by the reliable Mitsubishi 4M40 engine, delivering 41 kW of rated power while maintaining low fuel consumption. This engine is known for its durability, easy maintenance, and ability to perform consistently in high-altitude and cold environments, making the Cat 306D excavator suitable for diverse global working conditions.

Precision Hydraulic System

Featuring an advanced load-sensing hydraulic system, the Cat 306D adjusts oil flow and pressure based on load demands, ensuring smooth, responsive operation with minimal energy waste. This system enables accurate control of excavation, lifting, and attachment functions, reducing operator fatigue and improving work efficiency.

Compact & Maneuverable Design

With a minimal tail swing radius and compact footprint, the Cat 306D crawler excavator excels in confined spaces such as urban construction sites, residential backyards, and indoor demolition projects. Its 4.8 km/h travel speed and 48.2 kN maximum traction force allow it to navigate rough terrain and steep slopes with ease.

The fully enclosed ROPS/FOPS-certified cab provides excellent visibility, low noise levels, and shock absorption, creating a comfortable working environment for long shifts. Optional air conditioning and ergonomic controls further enhance operator comfort, reducing fatigue and improving safety on the job site.

Easy Maintenance & Durability

Designed with serviceability in mind, the Cat 306D features large side doors and ground-level maintenance points, allowing quick access to key components like filters, fluids, and engine parts. The reinforced undercarriage and heavy-duty boom/arm construction ensure long-term durability, even with frequent use in demanding applications.
