Complete Range for Precise Application Matching

The CAT® lineup seamlessly spans from 3 to 40 tons, ensuring the right machine for every task. Compact models like the 303 series offer exceptional agility and precision for confined spaces and fine grading. The industry-leading mid-size range, exemplified by the 320 series, delivers the perfect balance of power, versatility, and cost-effectiveness for general excavation, trenching, and material handling. Larger models like the 336 and 340 excavators provide unmatched digging force and durability for demanding quarry and heavy earthmoving applications. This tiered portfolio allows customers to precisely match machine capability to job requirements, optimizing fleet investment and project outcomes.

Consistent Performance and Intelligent Efficiency

Across the entire range, advanced Cat engines and hydraulic systems deliver robust power integrated with intelligent fuel efficiency features. From the smallest to the largest model, each excavator is designed to minimize fuel consumption and emissions within its class, significantly reducing operating costs. The refined hydraulic systems provide smooth, responsive control across all models, enabling operators to execute tasks with confidence—from delicate landscaping to aggressive rock digging.

Operator-Focused Comfort and Uncompromising Reliability

A human-centered design philosophy is paramount throughout the Cat excavator family. All operator stations are engineered for comfort and productivity, featuring spacious cabs, suspension seats, intuitive low-effort controls, and excellent all-around visibility. High-performance climate control systems maintain a comfortable environment in all weather conditions, helping operators stay focused and productive. Built with durability as a cornerstone, every Cat excavator, regardless of size, utilizes high-strength components and undergoes rigorous testing to maximize uptime and ensure project schedule adherence.

Smart Technology and Data-Driven Insights

Digital innovation is embedded across the lineup. Most machines are equipped with Cat® Connect technology, utilizing integrated monitoring systems to provide real-time data on location, machine health, productivity, and maintenance alerts. This connectivity empowers fleet managers—whether overseeing a few machines or a large fleet—to make proactive decisions, optimize maintenance planning, improve jobsite efficiency, and maximize asset utilization through actionable insights.
