*A Beginner Operator’s First Loads: Caterpillar 390D Excavator in Action*
In today’s video, we follow a beginner operator as he takes on his first real task at a mining site. Behind the controls of the powerful Caterpillar 390D Excavator, he loads blasted material into Mercedes Arocs and MAN 4-axle trucks. Watching the operator learn the ropes on this impressive machine provides a fascinating glimpse into the start of a mining career, and the capabilities of the equipment are on full display.
*Caterpillar 390D Excavator: A Mining Powerhouse*
The Caterpillar 390D is designed for heavy-duty work in mining and construction environments. With its advanced hydraulics, large bucket capacity, and robust design, this excavator is capable of handling challenging material with ease.
Key Specifications:
• Operating Weight: 89,000–98,000 kg (196,000–216,000 lbs), offering excellent stability for large-scale tasks.
• Engine Power: Equipped with a Cat C18 ACERT engine, delivering 523 horsepower (390 kW) for reliable and consistent performance.
• Bucket Capacity: Ranges from 3.8 to 5.8 cubic meters (5 to 7.6 cubic yards), enabling it to move significant volumes of material in every pass.
• Maximum Digging Depth: 7.9 meters (26 feet), making it effective for deep excavation tasks.
• Maximum Reach: 13.28 meters (43.5 feet), allowing it to efficiently load large trucks without repositioning.
• Hydraulics: The advanced hydraulic system ensures smooth and precise movements, even under heavy loads.
*Mercedes Arocs and MAN 4-Axle Trucks: Sturdy Haulers*
The material excavated by the Caterpillar 390D is loaded into Mercedes Arocs and MAN 4-axle trucks, both well-suited for transporting heavy materials across mining terrains.
Mercedes Arocs:
• Payload Capacity: Handles up to 40 metric tons, making it ideal for transporting blasted material.
• Engine Power: Equipped with engines producing up to 510 horsepower, ensuring smooth hauling over rough terrain.
• Durability: Built with reinforced chassis and efficient suspension systems to handle heavy-duty operations.
MAN 4-Axle Trucks:
• Payload Capacity: Similar to the Arocs, capable of hauling up to 40 metric tons.
• Engine Power: Powered by engines delivering up to 480 horsepower, providing reliable performance under load.
• Efficiency: Designed for fuel efficiency and minimal wear during long cycles in demanding environments.
*The Workflow: A Beginner’s Approach*
As this is the operator’s first loading task, the workflow reflects a mix of learning and progress as he gets comfortable with the Caterpillar 390D.
1. Excavating the Material:
The operator positions the bucket over the blasted material and begins scooping. The advanced controls and hydraulics of the Caterpillar 390D allow for smooth operation, aiding the learning process.
2. Positioning Over the Trucks:
Once the bucket is filled, the operator maneuvers the excavator to position the load over the truck beds. With its wide reach and high lift capacity, the 390D makes this step easier, even for a beginner.
3. Loading the Trucks:
The operator carefully dumps the material into the Mercedes Arocs and MAN trucks. Despite being new to the role, the operator starts to establish a steady rhythm, increasing efficiency with each load.
4. Cycle Continuation:
After a few cycles, the trucks depart to dump the material, and the process repeats with new arrivals.
