Key Specifications

• Model: CAT 6090 FS (Face‑Shovel Mining Hydraulic Excavator)
• Operating Weight: 980 t
• Standard Bucket Capacity: 52 m³, rated payload per bucket reaches 93.6 tons
• Power Configuration: Equipped with twin Cummins QSK60‑V16 diesel engines, total power output 3360 kW (4500 HP). Each engine delivers 60.2 L displacement. The dual‑power redundant design allows the unit to maintain basic operation with one power group in case of single‑side failure, minimizing mine production downtime.
• Fuel Consumption: Under full‑load mining conditions, hourly fuel consumption is approximately 1100‑1200 L/h. The large‑capacity fuel tank supports long‑duration continuous mining shifts. Its high fuel consumption matches its massive material‑handling capacity.
• Travel & Structure: Track shoe width 2000 mm, maximum travel speed 2.2 km/h, maximum gradeability 44%. Due to its enormous overall dimension, the machine cannot be transported as a complete unit. It must be disassembled into multiple large components for shipping and assembled on‑site at the mine before commissioning.

Working Efficiency & Equipment Configuration

The CAT 6090 FS is built purely as a face‑shovel machine with no back‑shovel variant. It adopts the Caterpillar TriPower heavy‑duty linkage system, which keeps consistent bucket tilt angles throughout lifting strokes, reducing operator adjustment and shortening cycle times for stable loading performance.

Eight variable axial piston main pumps deliver abundant high‑pressure hydraulic flow. Total hydraulic oil volume reaches around 13 000 liters, providing powerful digging force for lifting, slewing and dumping. A complete working cycle takes roughly 30 seconds.

Under typical mine conditions, average material handling capacity hits 5 500 tons per hour with peak throughput up to 9 000 tons per hour. It perfectly matches 360‑400‑ton class mining dump trucks. Only 3‑4 bucket passes are required to fully load one heavy hauler, shortening loading cycles and greatly boosting overall mine throughput.

The operator cabin features panoramic visibility with vibration‑ and noise‑reduction design. Integrated intelligent fault diagnosis and automatic centralized lubrication systems lower failure rates under harsh mine conditions, enabling round‑the‑clock two‑shift continuous production in dusty, high‑impact heavy‑load mining environments.

Main Applications

This premium mining machinery is not designed for general earth‑moving projects. It serves large‑scale open‑pit coal mines, iron ore mines and non‑ferrous metal mines.

1. Overburden Removal: Stripping overlying rock and soil above ore bodies for mass earth‑moving tasks.
2. Ore Loading & Haulage: Directly excavating ore and fast‑loading material onto large mining dump trucks.
3. Mine Site Development: Pit expansion and slope trimming for mega‑scale open‑pit mining projects.

Normally deployed together with Caterpillar heavy‑duty mining haul trucks, this excavator suits open‑pit mines with annual output of tens of millions of tons. Its ultra‑high single‑unit throughput reduces the total quantity of site equipment and simplifies mine production management.

Summary

CAT 6090 FS | 980 t | 52 m³ is Caterpillar’s flagship mining excavator in construction machinery. Boasting nearly 1 000‑ton operating weight, 52‑cubic‑meter giant bucket, redundant dual‑engine power and massive hourly material throughput, it sets the benchmark for global hydraulic mining shovels. Despite high procurement, maintenance and fuel costs, it helps large open‑pit mines cut comprehensive operating costs and raise production efficiency, making it an iconic heavy‑duty workhorse for global mining operations.
