Product Summary
This 20.0-ton tracked digger combines a high-efficiency hydraulic system with a Tier 2 / Tier 3 compliant diesel engine, delivering bucket breakout forces up to 145 kN. Designed for continuous heavy-duty cycles, the machine achieves a digging depth of 6.7 meters and a dump height of 6.5 meters. With a 1.0 m³ heavy-duty bucket as standard, this crawler excavator ensures maximum productivity for infrastructure contractors and mining support operations.
Why Choose This Machinery
Compared to mainstream brands (Caterpillar, Komatsu), our tracked digger offers a 15-20% lower initial investment without compromising core durability. Key advantages include: 1) Reinforced undercarriage with 45mm triple-seal track links, 2) 18% lower fuel consumption via smart idle and load-sensing hydraulics, 3) 2,000-hour greasing intervals for swing bearing, reducing maintenance downtime, 4) Free wearing parts kit (track pads, bucket teeth, filters) with each unit, and 5) Complimentary global RoRo shipping to major ports (Houston, Rotterdam, Durban, Singapore). ROI typically achieved within 18-24 months for rental fleets.
Powertrain & Structural Overview
Engine: The Cummins QSB5.9-C145 turbocharged diesel engine delivers 145 HP @ 2000 RPM with high torque rise, ensuring stable hydraulic flow even under heavy loads. Fuel pre-filter and water separator included for harsh fuel quality markets.
Hydraulic System: A tandem variable-displacement axial piston pump generates main flow of 2x 220 L/min, combined with a pilot gear pump for precise control. Main relief valve set at 34.3 MPa (350 bar). Boom/arm regeneration circuits reduce cycle times by 8%.
Undercarriage & Structure: X-frame design with seven bottom rollers per side, track shoe width 600mm (700mm optional for swamp conditions). Swing circle with double-row ball bearings and induction-hardened gear. Cab features ROPS/FOPS certification, air-suspension seat, and an optional 7' LCD touchscreen monitor.

Heavy-Duty Application Scenarios
Earthmoving & Bulk Excavation
Ideal for residential/commercial site preparation, roadbed cutting, and canal digging. The 1.0m³ bucket combined with 5.8m boom/2.9m arm configuration enables 120-150 m³/h productivity in common soil (bank density 1,600 kg/m³).
Quarry & Aggregates Handling
Optional heavy-duty 0.8m³ rock bucket with wear-resistant steel liner and additional counterweight kit (total 21.2 tons) for ripping limestone, gravel, or decomposed granite. Boom/arm protection plates standard.
Municipal Infrastructure & Pipelaying
Equipped with optional hydraulic quick coupler and tilting bucket, the tracked digger performs trenching (max 6.7m depth) and pipe handling with fine swing control. Backup alarm and LED working lights for urban night operations.
Equipment Q&A
Q1: What is the minimum order quantity (MOQ) and export lead time?
A: MOQ is 1 unit for stock models. For 20-ton units, typical lead time is 15 working days from deposit to shipment from our Chinese export hub. Container shipping (1x 40' OT) available; RoRo vessels add 7-10 days for scheduling.
Q2: Which emission standards are available for different markets?
A: Standard configuration is EPA Tier 3 / EU Stage IIIA compliant (Cummins QSB). We can supply Tier 0 / Tier 1 engines for Africa, CIS, and Southeast Asia. DOC/SCR aftertreatment systems are optional for Tier 4F regions, subject to additional cost and lead time.
Q3: What spare parts are included in the standard wearing parts package?
A: Each tracked digger includes: 1 full set of bucket teeth + pins, 2 primary fuel filters, 2 oil filters, 2 air filter elements, and 4 track link rubber pads (or 2 steel track shoes). A 2,000-hour parts list is provided for local sourcing.
Q4: How is the one-year global warranty structured?
A: Warranty covers powertrain (engine, hydraulic pumps, swing motor, travel motor) and mainframe for 12 months or 2,000 hours, whichever comes first. We provide online diagnostic support, and for major claims, a partial advance replacement part is shipped via air freight. Consumables and wear items are excluded.
Q5: Do you provide operational training and manuals?
A: Yes. An English operator manual, service manual, and parts catalog are provided digitally (USB). Three hours of remote video training via WhatsApp/Teams is included. On-site training can be arranged for large fleet orders (5+ units).
