4 Ton Digger
Optimal Balance of Power and Portability: Provides the significant digging depth and breakout force required for heavy-duty foundation work while remaining compact enough to be transported on a standard trailer without special oversized permits.
Enhanced Multi-Function Productivity: Features advanced "Smart-Flow" hydraulic systems that allow for simultaneous traveling, swinging, and booming without power loss, reducing cycle times by up to 15% – 20% compared to smaller models.
Versatile Trenching and Digging Depth: Engineered to reach depths of 3.2m to 3.5m, making it the ideal choice for utility installations, septic tank placements, and residential basement excavations that are beyond the reach of 1-ton or 2-ton minis.
Superior Stability on Uneven Terrain: Built with a wider, reinforced undercarriage and longer track frames, ensuring maximum lifting stability and safety when handling heavy materials or operating on slopes and soft soil.
High-Torque Performance: Equipped with premium, fuel-efficient diesel engines (such as Kubota or Yanmar) that provide high torque at low RPMs, delivering the "pushing power" needed for backfilling and site grading with an angle blade.
Precision Pilot Control System: Utilizes ergonomic, short-throw hydraulic joysticks that offer smooth, surgical precision for working around existing underground utilities and sensitive structures.
Robust Attachment Integration: Comes standard with dual-way auxiliary hydraulic piping, allowing the machine to power heavy-duty attachments like large hydraulic breakers, high-torque augers, and tilt-rotators for diverse job site roles.
Operator-Centric "Command Center" Cab: Features a spacious, ROPS/FOPS certified cabin (or canopy) with panoramic visibility, digital monitoring displays, and enhanced suspension seating to minimize fatigue during full-shift operations.
Simplified Maintenance Architecture: Designed with large-opening side and rear service hoods, providing total ground-level access to the engine, cooling system, and hydraulic pump for fast daily checks and reduced downtime.
Professional 4 Ton Digger: High Power & Precision for Challenging Jobsites
Product Overview
Our 4 Ton Digger is the ultimate versatile workhorse, specifically engineered to provide the digging power of a larger machine while maintaining the maneuverability of a compact excavator. This 4-tonne powerhouse is a favorite among landscaping contractors, utility companies, and rental fleet managers who demand "Big Machine" breakout force in a package that is still easy to transport.
Built with a reinforced chassis and a high-efficiency hydraulic system, our 4t excavator excels in heavy-duty trenching, foundation work, and rock breaking. If you are looking for a reliable, factory-direct solution that bridges the gap between micro diggers and heavy excavators, this is the perfect asset for your fleet.

Key Features & Benefits
Elite Powertrain Performance: Equipped with world-renowned engines from Kubota or Yanmar, our 4-ton digger delivers high torque at low RPM. Fully compliant with EPA Tier 4 Final and Euro Stage V emissions, ensuring total legality in North America and Europe.
Load-Sensing Hydraulic System: Our advanced hydraulics automatically adjust oil flow to meet the demand of the task. This ensures smooth, simultaneous movements of the boom, arm, and bucket, while reducing fuel consumption by up to 12%.
Spacious FOPS/ROPS Cabin: The fully enclosed, pressurized cabin features a 360-degree panoramic view, integrated air conditioning, and a high-back suspension seat. Ergonomic hydraulic pilot joysticks provide the precision needed for delicate utility work.
Reinforced Undercarriage & Boom: Constructed with high-strength manganese steel, the X-frame chassis and reinforced boom are designed for long-term structural integrity. All hydraulic hoses are routed internally or protected by steel guards to prevent damage on-site.
Dual-Speed Travel System: Features an automatic downshift function that switches from high to low speed when extra traction is needed for climbing slopes or moving through soft mud.
Applications
The 4-tonne compact excavator is a multi-purpose powerhouse for:
Urban Construction: Road widening, sidewalk repairs, and deep utility trenching (water/gas/fiber).
Landscaping & Forestry: Clearing large-scale brush, digging swimming pools, and decorative rock placement.
Agriculture: Ditch cleaning, silage management, and heavy post-hole digging.
Demolition: Equipped with a hydraulic breaker for breaking up thick concrete foundations or stone walls.
Frequently Asked Questions (FAQ)
Is the 4 ton digger easy to transport between jobsites?
Yes. Despite its high power, its compact dimensions allow it to be moved on a standard equipment trailer. We have optimized the center of gravity to ensure stability during loading and transit.
Can I run high-demand hydraulic attachments like a mulcher?
Absolutely. The machine comes standard with dual-directional auxiliary hydraulic piping. The high-flow variable piston pump provides consistent oil flow, making it ideal for augers, breakers, and hydraulic grapples.
What is the expected maintenance interval?
Daily checks are made easy with the large-opening rear engine hood. We recommend hydraulic oil and filter changes every 500-1,000 hours, depending on operating conditions. All maintenance parts are standardized for easy local sourcing.
