Showcase: Large Wheel Loaders for Quarries and Aggregates (Part 2)

We've got some added value for you in this edition of Showcase.

Before we get to quarry and aggregate production models from Deere, Case, Komatsu, and Hitachi, we have buying advice from JCB.

Showcase: Large wheel loaders (Part 1)

"Whether loading haul trucks, managing stockpiles or feeding crushers, selecting the right machine starts with evaluating the features that most directly impact productivity, uptime, and operating costs," says James McMillan, product manager for JCB.

McMillan points to six keys to the decision.

Payload capacity

Choose a loader sized to move the maximum amount of material efficiently. Higher payload capacities can improve loading efficiency and lower fuel consumption across the operation.

"A larger payload capacity can also help reduce overall loadout times by moving more material with each pass," McMillan says.

Low-end torque, hydraulic performance

Strong low-end torque helps loaders push into dense aggregate piles and climb grades without losing momentum. Load-sensing hydraulics and lock-up torque converters can improve responsiveness while optimizing fuel efficiency.

Structural durability

"Aggregate and quarry sites are demanding on equipment," McMillan says. "Look for heavy-duty axles, reinforced articulation joints, and robust frame construction designed to withstand continuous loading cycles and rough terrain."

Operator comfort, visibility

Long shifts require a comfortable operator environment. Spacious cabs, ergonomic controls and clear visibility to bucket edges and surrounding equipment can help reduce fatigue and improve loading precision.

Safety features

"Backup cameras, wide-view mirrors and improved sightlines help operators maintain awareness in busy loading areas where trucks, personnel, and equipment constantly interact," McMillan says.

Maintenance and uptime

Ground-level service access, grouped maintenance points, and telematics systems simplify inspections and help crews identify maintenance needs before they lead to costly downtime.

X (Tier) marks the spot

The new John Deere 844 and 904 X Tier Wheel Loaders are built for high-volume material handling applications and feature the John Deere Electric Variable Transmission (EVT), an advanced drivetrain system that provides smoother operation, faster response, and optimized fuel efficiency.

Operators can choose between Standard Mode, which delivers up to 15% fuel savings, or Performance Mode for up to a 5% productivity boost, helping lower total cost of ownership.

Additional features include Pile Slip Assist technology for improved traction and bucket fill, larger high-strength steel buckets, and optional Advanced Vision System and Object Detection features that enhance visibility and jobsite awareness.

These new models also integrate with John Deere digital support solutions, including remote diagnostics and equipment management tools, helping customers streamline maintenance and maximize uptime.

This one goes to 11

With 345 horsepower and a 61,650-pound operating weight, the Case 1121G is designed for efficient truck loading and high-volume material handling.

Intelligent automation systems — including Auto Dig, Auto Dump, and Auto Meter — help operators reduce variability and improve cycle efficiency by minimizing over-digging and enabling repeat performance with stored, one-touch ideal bucket-fill cycles.

The updated cab includes premium heated and ventilated seating, improved Bluetooth connectivity, an updated noise-canceling microphone, seat belt indicator light, and rear object detection system. 

The 1121G is also available with Case’s X-Drive hydrostatic continuous variable transmission (CVT), delivering smoother acceleration, improved traction, reduced tire and axle wear, and up to 20% greater fuel efficiency compared to standard transmissions.

Coming soon, the 1121G will be available with customizable four-corner strobe lighting for enhanced safety and visibility in demanding environments.

Yard loader configuration

The Komatsu WA485-11 wheel loader with the yard loader (YL) configuration is engineered to maximize productivity and stability in high-volume material handling.

Designed as a 3-pass match for loading on-highway trucks, the WA485-11 YL combines a newly optimized 7.2- or 7.6-cubic-yard bucket with a heavier counterweight than Komatsu’s WA480-8, reinforced frame, heavy-duty axles, and wide low-profile tires to enhance durability in rugged quarry environments.

Its Komatsu Hydraulic Mechanical Transmission (KHMT) helps deliver strong acceleration and improved fuel efficiency, while increased breakout force and climbing performance support faster cycle times than prior models.

Advanced operator features include the automatic digging system, angle feedback joystick steering, independent work equipment controls, and high-visibility cab with a premium operator seat. Rear object detection technology comes standard and helps enhance operator awareness.

Hitachi

Hitachi Construction Machinery’s large wheel loaders are precision engineered for repetitive load-and-carry cycles and truck-loading operations, delivering consistently high productivity.

The ZW370-6 HC is a core machine for these environments. Specifically, the ZW370-6 HC is purpose-built for high-volume operations, featuring an 8.1-cubic-yard bucket capacity, a 79,210-pound operating weight, a 62,555-pound straight tipping load, and a 386-horsepower net engine output.

Key features:

• Joystick Steering: Less repetitive motion, reducing shoulder and wrist strain, and operator fatigue.
• Lock-Up Torque Converter: Boosts uphill travel speed while improving fuel efficiency.
• Active Engine Control System: Senses acceleration, digging, and approach to optimize engine speed, balancing low fuel consumption with high work power.
• ConSite: Supports remote monitoring and predictive maintenance, helping identify potential issues before they cause costly downtime.
