Komatsu presents innovation in motion during Quarry Days 2025

Deep in the heart of Sahuarita, AZ lies Komatsu’s 660-acre Arizona Proving Grounds (AZPG), where cutting-edge mining and construction equipment is put through its paces. Through its newly founded tradition called Quarry Days — an event that offers dealers and customers the opportunity to operate Komatsu mining and construction equipment — Komatsu provides patrons with the opportunity to learn about the latest technological innovations the company possesses. This exclusive event brought industry leaders, dealers and media together over the course of two weeks in February for an immersive experience surrounding the latest innovations that are shaping the future of mining operations. Spectators had the opportunity to witness live demonstrations, interact with product experts and operate state-of-the-art machinery. Komatsu has long been at the forefront of technological advancement in mining and construction equipment, and Quarry Days offered attendees an inside look at the company’s latest advancements. From autonomous haulage solutions to high-powered wheel loaders, this year’s event highlighted efficiency, productivity and sustainability in modern quarry operations. During Quarry Days, Komatsu spotlighted several new and enhanced machines, each designed to maximize productivity and reduce downtime. Among them was the HD605-10 mechanical haul truck, engineered for durability and efficiency with improved horsepower, faster uphill speeds and Smart Quarry Site integration for remote jobsite monitoring. It also featured Pronto AI’s autonomous haulage technology, currently being piloted in Texas. Designed to seamlessly pair with the HD605-10, Komatsu showcased the WA700-8 wheel loader, a powerhouse offering enhanced lifting force, an advanced joystick steering system and automation features that streamline repetitive tasks. Another wheel loader featured was the WA900-8, designed to match Komatsu’s 100-ton HD785-8 haul truck, delivering enhanced breakout force and Smart Quarry Site compatibility for real-time monitoring and performance tracking. Other haul trucks featured were the HD785-8 and HD1500-8E0 mechanical haul trucks, which offer superior payload capacities and innovative transmission systems to optimize fuel consumption and minimize material spillage. One of the captivating highlights of Quarry Days was Komatsu’s demonstration of Pronto AI, an autonomous haulage solution for quarry-sized trucks. Pronto’s vision-based autonomy system eliminates the need for expensive lidar sensors, making automation more accessible for quarry operators. By reducing the need for human drivers, Pronto AI technology helps quarries address labor shortages while increasing productivity by up to 20 percent per truck. Komatsu used Pronto AI in front of spectators to autonomously operate the WA700-8 wheel loader and the HD605 mechanical haul truck. During the demonstration, the WA700-8 scooped up to a heap of dirt, as the HD605 haul truck backed up into formation, perfectly placing its bed under the dozer’s arm. The wheel loader dropped the pile of dirt into the bed of the HD605, which then proceeded to drive off. The entire presentation was controlled by the connected Pronto AI system, located directly in front of the audience. In relation to dozers, the D475A-8 surface mining dozer also made an appearance, revealing its build for longevity and productivity, and featuring a robust mainframe engineered for multiple rebuild cycles. The D475A-8 also encompasses an advanced traction system that increases pushing power and ripping efficiency. Pairing nicely with the dozers were the excavators, showcasing the PC2000-11 excavator, which boasts increased horsepower and a redesigned hydraulic system. Its hydraulic system enables faster cycle times and superior performance in stripping applications and overburden removal, giving it an advantage compared to other machinery. Portraying versatility on difficult terrain was the HM400-5 articulated truck, showing a viable option with an automated traction control system to ensure seamless operation in challenging underfoot conditions. Following suit for haul road maintenance solutions was the GD955-7 motor grader, engineered for precision and featuring an 18-ft moldboard with up to 33 percent increased productivity over previous models. Focusing on sustainability, the HB365LC-3 hybrid excavator stood out for its energy efficiency, reducing fuel consumption and carbon dioxide emissions by up to 20 percent, and an intelligent energy recovery system that optimizes digging cycle times. The ZT44 drill was also available on site, demonstrating its build for longevity and precision due to providing reliable performance in extreme environments with a high-pressure compressor and flexible drilling depth capabilities. In addition, the Stamler RF-5 reclaim feeder was visible, highlighting its modular, cost-efficient material blending and feeding system designed for seamless integration into cement plants, ports, refineries and mines. Along with highlighting new equipment and its autonomous operating systems, Komatsu is currently pushing the boundaries of intelligent quarry management with its Smart Quarry Site platform, a system that was prevalent throughout Quarry Days. Designed to optimize fleet operations, Smart Quarry Site provides real-time data on fuel consumption, idle time and machine utilization, helping operators maximize efficiency and reduce costs. As Komatsu continues to refine its equipment offerings, the company has already developed new machines set for release this year. These upcoming models promise further advancements in efficiency, automation and sustainability, aligning with Komatsu’s vision of an empowered, eco-conscious mining industry. With Quarry Days 2025, Komatsu reaffirmed its commitment to innovation, customer collaboration and sustainable mining solutions. Attendees left not just with insight into the latest advancements but with firsthand experience of the future of quarry operations. As technology evolves, it is clear Komatsu is contributing to a smarter, safer and more efficient industry.
