*Power at Work: Komatsu D475A Bulldozer Ripping Hard Ground with Excavators Loading in the Background*
In today’s video, we’re watching a powerhouse in action—the Komatsu D475A bulldozer ripping through hard ground. This impressive machine showcases its strength and versatility as it tackles the challenging terrain, while in the background, we see a Liebherr 994 front shovel excavator and a Terex RH170 front shovel excavator loading Hitachi dumpers. The scene is a perfect demonstration of the power and efficiency required for large-scale mining operations. With each push, the Komatsu D475A proves its capability, and the precision of the operator further emphasizes the bulldozer’s rugged design and performance.
*Komatsu D475A Bulldozer: A Giant Built for the Toughest Tasks*
The Komatsu D475A is one of the largest bulldozers in Komatsu’s lineup, purpose-built for intense applications like mining and quarrying. Known for its stability, power, and efficiency, the D475A is engineered to handle extreme workloads, from pushing overburden to ripping hard surfaces. Here’s a closer look at the specifications that make it a powerhouse on the job:
Engine Power: The Komatsu D475A is equipped with a Komatsu SA12V140E-3 engine that delivers an impressive 890 horsepower (664 kW). This immense power output gives the bulldozer the muscle it needs to tackle hard ground with ease, making it ideal for ripping and pushing through tough materials.
Operating Weight: With an operating weight of around 108 tons, the D475A provides the stability required to handle challenging tasks without losing control. This weight keeps the bulldozer steady, even when working on uneven terrain or under heavy loads, ensuring smooth, efficient movement.
Blade Capacity: The D475A features a semi-U blade with a capacity of approximately 34.4 cubic yards (26.3 cubic meters), allowing it to move substantial amounts of material in each pass. This capacity is crucial for high-production environments, minimizing the number of passes required and keeping productivity high.
Ripping Depth: Equipped with a robust single-shank ripper, the D475A can achieve a maximum ripping depth of up to 2 meters. This feature is essential for breaking up compacted, rocky ground, allowing excavators and dumpers to work more efficiently in prepped areas.
The D475A’s power, weight, and ripping depth make it a versatile machine for the most challenging environments, from hard earth to rocky surfaces. In today’s video, the bulldozer’s strength is on full display as it handles hard terrain without hesitation.
*Liebherr 994 Front Shovel Excavator: Heavy-Duty Loading Power*
In the background, we see the Liebherr 994 front shovel excavator loading massive amounts of material into Hitachi dumpers. Built for high-production environments, the Liebherr 994 is a powerful machine that complements the bulldozer’s work, quickly loading heavy material onto trucks for transport.
Here’s a look at the specifications that make the Liebherr 994 a top choice for mining and heavy construction:
Engine Power: The Liebherr 994 is equipped with a robust Liebherr D9508 V8 engine that delivers approximately 1,450 horsepower (1,081 kW). This engine power allows the excavator to handle heavy materials and maintain high productivity even during continuous operation.
Operating Weight: With an operating weight of around 200 tons, the Liebherr 994 is stable and balanced, even when lifting full buckets of material. This weight provides the necessary stability for handling the large loads typical in mining operations.
Bucket Capacity: The 994 is equipped with a front shovel bucket that can hold up to 25 cubic yards (19 cubic meters) of material, enabling it to load dumpers with fewer passes. This capacity is essential for maximizing productivity, ensuring that each load is efficiently filled before transport.
*A Team Effort: High-Efficiency Operation*
The combination of the Komatsu D475A bulldozer ripping the ground and the Liebherr 994 front shovel excavator loading dumpers shows the coordinated effort required for efficient mining operations.
