Precision Excavation and Expert Coordination: The Caterpillar 345C Excavator and 140H Grader in Action
In today’s video, we are witnessing the impressive Caterpillar 345C hydraulic excavator as it tackles the challenging task of loading four-axle trucks on a double-sided ramp in a busy mining operation. This high-stakes environment demands precision, speed, and expertise, and the operator’s skill with the 345C shines through as each truck is loaded quickly and efficiently. Working alongside this powerhouse, the Caterpillar 140H grader ensures the loading area remains smooth and clear, maintaining optimal conditions for the continuous flow of trucks.

Caterpillar 345C Hydraulic Excavator: Power and Precision
The Caterpillar 345C hydraulic excavator is a robust piece of machinery designed for heavy-duty applications, making it a perfect fit for mining operations like the one featured in today’s video. Built for strength and precision, the 345C is capable of moving large quantities of material with speed, making it ideal for loading trucks quickly on a double-sided ramp.

Engine Power: The 345C is equipped with a Caterpillar C13 ACERT engine, delivering 345 horsepower (257 kW). This powerful engine allows the excavator to operate efficiently, even when dealing with dense, challenging materials typical in mining.

Operating Weight: The 345C has an operating weight of around 45 tons (45,000 kg), providing the stability needed for lifting and loading heavy material. This weight ensures the machine remains balanced and secure, even when working at height on a ramp.

Bucket Capacity: With a bucket capacity ranging from 2.5 to 3.2 cubic meters, the 345C can lift significant amounts of material per scoop. This high-capacity bucket reduces the number of cycles needed to fill each truck, allowing for quick turnaround times and keeping the loading process efficient.

Hydraulic System: The advanced hydraulic system in the 345C provides smooth, responsive control, allowing the operator to make precise movements while handling heavy loads. This is especially important when working on a double-sided ramp, where accuracy is crucial to avoid spillage and ensure that each load is delivered exactly where it’s needed.

Digging Depth and Reach: The 345C offers a maximum digging depth of around 8 meters and a reach of over 11 meters. This reach is essential when working on ramps, as it allows the operator to load trucks positioned on either side without needing to reposition the machine frequently.

Precision Loading on a Double-Sided Ramp
Loading on a double-sided ramp adds an extra layer of complexity to the job, requiring the operator to maintain precise control over the excavator’s movements to ensure smooth and efficient loading. The double-sided ramp setup allows multiple trucks to be loaded simultaneously, but it also means that space is limited, and each movement must be carefully calculated.

Caterpillar 140H Grader: Maintaining a Clean and Safe Loading Area
While the Caterpillar 345C focuses on loading, the Caterpillar 140H grader plays a vital supporting role, ensuring that the loading area remains smooth, level, and free of debris. The grader’s presence is essential for maintaining optimal conditions in a high-traffic zone like a loading ramp, where uneven surfaces can slow down operations or cause safety risks.

Engine Power: The 140H grader is equipped with a Caterpillar 3306 engine, delivering around 185 horsepower (138 kW). This power allows the grader to maintain consistent performance, even when dealing with compacted materials and rough terrain.

Operating Weight: With an operating weight of approximately 15 tons (15,000 kg), the 140H is both stable and maneuverable, making it ideal for grading tasks in confined areas like loading zones.

Blade Width and Reach: The 140H features a moldboard (blade) width of around 3.7 meters, which allows it to cover a large area with each pass.
