Engine Power: Features a Komatsu SA12V140E-3 engine delivering 856 horsepower (638 kW).
Bucket Capacity: Ranges from 11 to 13 cubic meters (14.4 to 17 cubic yards).
Specialty: Handles mid-size marble blocks and clears debris efficiently, ensuring a clean working area for extraction.

Caterpillar 992D: A Workhorse for Massive Loads

The Caterpillar 992D is a legend in the world of wheel loaders, designed to handle the largest and heaviest materials in mining and quarrying.

Operating Weight: Approximately 94,000 kg (207,000 lbs).
Engine Power: Powered by a Cat 3412 engine, delivering 814 horsepower (607 kW).
Bucket Capacity: Up to 12 cubic meters (15.7 cubic yards).
Lift Height: Offers a dump clearance of around 4.3 meters (14.1 feet).
Role in Quarry: Moves and loads massive marble columns and blocks onto transportation trucks with ease.

Caterpillar 988K Block Handler: The Specialist

The Caterpillar 988K Block Handler is specifically designed for handling oversized materials like marble blocks.

Operating Weight: About 116,400 lbs (52,800 kg).
Engine Power: Equipped with a Cat C18 ACERT engine, providing 541 horsepower (403 kW).
Special Fork Attachments: Can lift and carry payloads of up to 44,000 lbs (20,000 kg), tailored for marble operations.
Lift Height: Reaches 15 feet (4.57 meters), making it suitable for loading high-sided trucks.
Primary Function: Lifting and precisely placing marble blocks for transportation or cutting.

Komatsu WA600: The Agile Assistant

The Komatsu WA600 plays a vital role in cleaning and preparing areas for extraction and cutting.

Operating Weight: Approximately 54,000 kg (119,000 lbs).
Engine Power: Powered by a Komatsu SAA6D170E-5 engine, producing 527 horsepower (393 kW).
Bucket Capacity: Between 6.4 and 7 cubic meters (8.4 to 9.2 cubic yards).
Purpose: Ideal for clearing debris and smaller marble pieces, ensuring a smooth workflow.
The Workflow: From Quarry to Factory
Extraction: Marble blocks are cut from the quarry walls using precision techniques. Excavators assist in this phase, loosening and preparing the blocks for handling.
Clearing and Lifting: Machines like the Komatsu WA600 clear debris, while loaders like the Caterpillar 988K Block Handler lift and place the massive blocks.
Loading: The Caterpillar 992D, Komatsu WA800, and WA900 handle the heaviest loads, moving marble blocks onto dumpers for transportation.
Transport: Trucks carry the blocks to nearby factories for further processing, such as cutting, polishing, and shaping into finished products.
