Product Summary
The Wear-resistant Digger WD220 is a purpose-built 22-ton crawler excavator that combines high-tensile steel fabrication with a fuel-optimized Isuzu 4HK1X diesel engine. Ideal for continuous mining support, heavy earthmoving, and aggregate handling. All units undergo a 12-point factory inspection before export, supported by genuine spare parts availability and a 1-Year Global Warranty covering major powertrain components.
Why Choose This Machinery
Compared to standard 20-22 ton excavators, the WD220 delivers +18% bucket tearout force (152 kN) and features a reinforced undercarriage with triple-flange track rollers. Key competitive advantages: 12% lower fuel consumption per cubic meter via load-sensing hydraulics; RoRo & 40ft HC container shipping compatibility (standard bucket removed); 24-hour parts dispatch from our global warehouses; and free operator e-training included with each machine. ROI typically achieved within 14-18 months for rental fleets.
Powertrain & Structural Overview
The Wear-resistant Digger WD220 is powered by an Isuzu 4HK1X turbocharged diesel engine meeting Tier 3 / Stage V equivalent emissions (customizable). The hydraulic system features Kawasaki main pumps and Rexroth control valves, enabling simultaneous boom, arm, and bucket operations without power loss. The reinforced X-frame undercarriage uses induction-hardened pins and bushings, extending service life in abrasive conditions by ~2,000 hours. Cab includes ROPS/FOPS certification, auto climate control, and a 7-inch LCD monitor with real-time fuel and filter alerts.
Technical Specifications
Below is the primary data for the Wear-resistant Digger WD220. All parameters are based on standard configuration with a 1.0 m³ general-purpose bucket.
Heavy-Duty Application Scenarios
Earthmoving
High-volume dirt relocation, road subgrade preparation, and canal digging. The wear-resistant bucket and reinforced linkage maintain productivity in rocky or compacted soils.
Quarry & Aggregates
Load-out of blasted rock, hopper feeding, and stockpile management. Optional heavy-duty rock bucket and side cutters reduce downtime by 30% compared to standard units.
Municipal Construction
Utility trenching, foundation excavation, and drainage projects. Short tail swing radius (2,150 mm) allows operation in confined urban job sites.
Equipment Q&A
Q1: What is the shipping lead time for the Wear-resistant Digger to major global ports?
A1: For stock units, shipping lead time is 7-12 days after payment confirmation. RoRo vessels depart weekly from Shanghai, Tianjin, and Ningbo. Container shipping (split into two 40ft HC flat racks) adds 3-5 days for packing. Delivery to North Europe, Middle East, or Southeast Asia typically ranges 25-40 days total.
Q2: Do you offer a free wearing parts package with the first order?
A2: Yes, every new WD220 includes a complimentary 1,000-hour wear kit (bucket teeth, side cutters, track pad bolts, and hydraulic return filter). For B2B wholesale contracts (≥5 units), we double the kit and add two sets of aftermarket bucket pins and bushings.
Q3: Which emission standards are available for different export markets?
A3: We offer three engine variants: Isuzu Tier 3 (for Africa, South America, Southeast Asia, CIS), Isuzu Stage V (EU, UK, Turkey), and optional Cummins QSB4.5 Tier 4 Final (North America). All models are customs-cleared with proper CO and EPA/EU conformity documents.
Q4: What operational training do you provide for our site mechanics?
A4: Each machine comes with a multilingual service manual and video tutorials (USB drive). We also provide one free remote start-up assistance (via video call). For fleet buyers, a 3-day on-site training in China is available (accommodation included) with certification upon completion.
Q5: How does the 1-Year Global Warranty work for remote sites?
A5: Coverage includes engine, hydraulic main pumps, swing motor, and travel motors. For warranty claims, you submit a video diagnosis. Approved repairs are covered by advance part replacement (air or sea). Labor is reimbursed at $85/hour for up to 20 hours per claim. Wear items, hoses, and seals are excluded.
