Caterpillar 385C Excavator – Power & Precision in Coal Mining
The Caterpillar 385C excavator is a true workhorse when it comes to high-production mining and excavation. Its massive bucket capacity and hydraulic power make it ideal for quick and efficient coal loading operations.
Key Specifications of the Caterpillar 385C:
- Operating Weight: 85,000 kg (187,393 lbs)
- Engine Power: 382 kW (513 HP)
- Bucket Capacity: 4.6 – 5.4 m³ (6 – 7 yd³)
- Max Digging Depth: 8.8 m (28.9 ft)
- Max Reach at Ground Level: 13.9 m (45.6 ft)
- Hydraulic System Pressure: 35,000 kPa (5,076 psi)
With its high digging force and rapid cycle times, the Caterpillar 385C ensures continuous loading, allowing trucks to haul coal efficiently from the excavation site.
Loading Coal onto 4-Axle Trucks – A High-Efficiency Process
Coal mining requires a seamless workflow between excavators and trucks, ensuring a constant supply of material for transportation. The Caterpillar 385C excavator, painted in white, effortlessly fills 4-axle trucks with precision and speed.
Step-by-Step Coal Loading Process:
- Positioning the Trucks:
- The 4-axle trucks align perfectly for efficient coal loading.
- Proper positioning ensures balanced weight distribution in the truck bed.
- Excavation & Loading:
- The Caterpillar 385C scoops up large amounts of coal with each pass.
- With only a few bucket loads, the trucks are fully loaded and ready for transport.
- Continuous Hauling & Return:
- As one truck leaves, another quickly moves into position.
- This keeps the operation running smoothly and prevents downtime.

Caterpillar D6R Bulldozer – Preparing the Ground for Continuous Excavation
Alongside the Caterpillar 385C, the Caterpillar D6R bulldozer plays a crucial role in maintaining the excavation area. After each round of coal extraction, the bulldozer levels and compacts the ground, ensuring that the site remains safe and accessible for further digging.
Key Functions of the Caterpillar D6R Bulldozer:
- Leveling the Excavation Area to provide a smooth surface for continued digging.
- Clearing loose coal and debris, reducing obstacles for the excavator and trucks.
- Ensuring Stability by compacting the soil to prevent machinery from getting stuck.
- Optimizing Truck & Excavator Movement, keeping the operation flowing without interruptions.
