Product Features & Advantages
Powerful & Efficient Cat C13 Engine
The Cat 350 is powered by a Cat C13 diesel engine that meets Tier 4 Final/Stage V emissions standards, delivering 310 kW of rated power for heavy-duty tasks. The engine is designed with advanced fuel-saving technologies, including automatic idle shutdown and eco-mode, reducing fuel consumption without compromising performance. Its robust construction ensures reliable operation in extreme temperatures and high-altitude environments, making it suitable for diverse worksites worldwide.
High-Efficiency Hydraulic System
The excavator features a closed-center load-sensing hydraulic system that delivers smooth, responsive operation for digging, lifting, and attachment work. The system’s high pressure and flow rates enable efficient operation with large buckets, hammers, and other heavy attachments, while swing priority function ensures fast cycle times for loading and material handling tasks. The system is designed for minimal pressure loss, maximizing power transfer and overall efficiency.
Reinforced Structure & Heavy-Duty Undercarriage
Built with high-strength steel and reinforced boom, arm, and bucket linkages, the Cat 350 is engineered to withstand the rigors of mining and quarrying work. The heavy-duty undercarriage features durable tracks, rollers, and idlers, providing excellent traction and stability on rough, uneven terrain. The machine’s robust frame and structural components are tested for long-term reliability, reducing maintenance needs and extending service life in the harshest conditions.
Operator-Friendly Cabin & Safety Features
The spacious, pressurized operator cabin is designed for comfort and safety, featuring a fully adjustable air-suspension seat, ergonomic controls, and a large touchscreen display for monitoring machine performance. The ROPS/FOPS compliant structure protects the operator from rollover and falling object hazards, while 360-degree visibility and rearview cameras enhance worksite safety. Low noise and vibration levels reduce operator fatigue, improving productivity during long shifts.
Low Maintenance & High Uptime Design
The Cat 350 is designed for easy maintenance, with ground-level access to all key service points, including oil filters, fuel filters, and hydraulic components. Extended service intervals for engine oil, hydraulic fluid, and filters reduce downtime, while the machine’s built-in diagnostic system allows for quick troubleshooting. Cat’s global service network and readily available spare parts ensure minimal downtime and reliable support for your operations.
Product Application Scenarios
Mining & Quarrying: Overburden removal, material loading, and site preparation in open-pit mines and quarries, where high power and durability are critical.
Large-Scale Earthmoving: Land development, site clearing, and excavation for commercial and industrial building projects.
Road & Infrastructure Construction: Earthmoving, foundation digging, and bridge construction projects, handling large volumes of material with efficiency.
Demolition & Recycling: Working with heavy demolition hammers and grapples to break down large structures and process debris in industrial sites.
Port & Material Handling: Loading and unloading bulk materials at ports and logistics centers, using large buckets and specialized attachments.
Packaging & Transportation
The Cat 350 excavator is prepared for safe international shipping with professional care to ensure it arrives in perfect condition. The machine is partially disassembled as needed for ocean freight, with the boom, arm, and bucket secured separately in a 40ft container. All exposed metal surfaces are treated with anti-corrosion coating, and critical components such as the engine, hydraulic system, and cabin are wrapped in protective film and foam to prevent damage during transit. Heavy-duty chains and wooden supports are used to secure the machine and its parts inside the container, preventing shifting during loading, unloading, and sea transport. Before shipment, a full inspection is conducted to verify fluid levels, system functionality, and the integrity of all components. We provide complete shipping documents, including packing lists, export certificates, and customs clearance forms, to facilitate smooth delivery at the destination port.
