*A Symphony of Machines: Komatsu WA900, WA600, Caterpillar 992D, and Komatsu PC400 in Action*
Today’s video showcases a synchronized team of heavy machinery operators working seamlessly in a marble quarry. Each machine plays a specific role in the process, from extracting and cleaning to transporting massive marble columns. The result is a display of power, precision, and teamwork as the Komatsu PC400 Excavator, Komatsu WA900, Komatsu WA600, and Caterpillar 992D Wheel Loaders handle the challenges of marble quarrying. Let’s dive into the details and specs of these impressive machines.
*Komatsu PC400 Excavator: Opening the Quarry*
The operation begins with the Komatsu PC400 Excavator, which is tasked with removing marble columns from the quarry face. This versatile excavator combines strength and precision, making it ideal for such delicate yet heavy-duty tasks.
Operating Weight: Approximately 40,700 kg (89,700 lbs), providing stability for demanding quarry tasks.
Engine Power: Powered by a Komatsu SAA6D125E-5 engine, delivering 370 horsepower (276 kW).
Bucket Capacity: Standard buckets range from 1.9 to 2.5 cubic meters (2.5 to 3.3 cubic yards), though specialized attachments are often used in quarrying.
Maximum Digging Depth: 7.9 meters (25.9 feet), allowing it to handle large cuts in the marble face.
Reach: With a maximum reach of 12.3 meters (40.3 feet), the PC400 excels at moving materials efficiently.
The PC400’s role in the operation is crucial—it carefully dislodges and drops the marble columns, setting the stage for the loaders to take over.
*Komatsu WA600: Clearing the Path*
Once the marble columns are on the ground, the Komatsu WA600 Wheel Loader steps in to clean the area, removing debris and preparing the site for efficient material handling. Its robust design and excellent maneuverability make it perfect for this role.
Operating Weight: Approximately 54,000 kg (119,000 lbs).
Engine Power: Equipped with a Komatsu SAA6D170E-5 engine, delivering 527 horsepower (393 kW).
Bucket Capacity: Ranges from 6.4 to 7.0 cubic meters (8.4 to 9.2 cubic yards), ideal for clearing debris quickly.
Lift Height: A maximum lift height of 4.25 meters (13.9 feet) ensures it can handle and relocate large volumes of material.
Traction and Control: Designed with superior grip and hydraulics, the WA600 excels on uneven quarry terrain.
The WA600’s precision and efficiency ensure the area is cleared quickly, enabling the larger loaders to focus on transporting the marble blocks.
*Caterpillar 992D: Moving the Marble*
The Caterpillar 992D Wheel Loader is brought in to handle the heavy lifting of marble columns. Its massive frame and high-capacity bucket make it a reliable workhorse in the quarry.
Operating Weight: Around 94,000 kg (207,000 lbs), providing stability for moving enormous loads.
Engine Power: Powered by a Cat 3412 engine, producing 814 horsepower (607 kW).
Bucket Capacity: Offers a capacity of up to 12 cubic meters (15.7 cubic yards), allowing it to handle marble blocks efficiently.
Lift Capacity: Built to move loads exceeding 20,000 kg (44,000 lbs) with ease.
Mobility: The 992D’s robust tires and advanced hydraulics ensure smooth operations on uneven surfaces.
*Komatsu WA900: The Heavy Hauler*
For the largest marble columns, the Komatsu WA900 takes over. Known for its incredible power and capacity, it works alongside the Caterpillar 992D to transport and load marble blocks onto dumpers.
Operating Weight: Approximately 108,000 kg (238,000 lbs).
Engine Power: Powered by a Komatsu SA12V140E-3 engine, generating 899 horsepower (671 kW).
Bucket Capacity: Capable of holding up to 13.0 cubic meters (17 cubic yards), making it ideal for the largest loads.
Lift Height: Offers a lift height of 4.6 meters (15 feet), ensuring compatibility with large dump trucks.
Productivity: Built for high-volume material handling, reducing cycle times in large quarry operations.
