Product Summary
The Used Caterpillar 320D2 Digger is a 20-ton class hydraulic excavator engineered for high-volume earthmoving, quarry overburden removal, and municipal infrastructure projects. Powered by a Caterpillar C4.4 ACERT engine delivering 150 horsepower, this machine achieves up to 15% lower fuel consumption compared to previous D-series models. Its reinforced undercarriage and heavy-duty boom/arm configuration support demanding continuous operation in ambient temperatures up to 52°C (125°F). Every unit undergoes a 312-point inspection before export and is backed by a 1-Year Global Warranty covering powertrain and hydraulic system failures.
Why Choose This Machinery
Unlike dealer-refurbished units with cosmetic-only repairs, our used CAT 320D2 diggers are sourced directly from managed fleets in the UAE, Australia, and South America. Each machine receives genuine CAT spare parts for all wear components prior to shipment. Key competitive advantages: (1) Hydraulic efficiency – Variable displacement axial piston pumps deliver 242 L/min flow at 34.3 MPa, enabling simultaneous boom, arm, and bucket operation with minimal cycle time loss; (2) Undercarriage durability – Sealed and lubricated track chains with 700mm triple-grouser shoes extend replacement intervals by 30% over aftermarket alternatives; (3) Global compliance – Machines can be pre-configured to EU Stage IIIA, EPA Tier 3, or China National IV emission standards at no additional cost; (4) Supply chain speed – In-stock inventory allows 7-day container loading from our Dubai or Houston consolidation yards, with RoRo vessel options for larger orders of 5+ units.
Powertrain & Structural Overview
The CAT C4.4 ACERT engine utilizes common rail fuel injection and an electronically controlled wastegated turbocharger to maintain peak torque of 460 N·m from 1,400 to 1,800 rpm. The hydraulic system features a closed-center, load-sensing design with two variable-displacement pumps and one gear pump for pilot control. Maximum auxiliary flow of 140 L/min supports hydraulic hammers, compactors, and shears. The cab ergonomics include an air-suspension seat, automatic climate control, and a 5-inch LCD monitor displaying real-time fuel burn, maintenance intervals, and hydraulic oil temperature. Structural reinforcements include a one-piece cast steel boom foot and high-tensile steel arm with internal baffles to absorb shock loads during rock excavation.
Technical Specifications
Below is the primary data for the used CAT 320D2 digger as measured under ISO 9245 standards. All parameters are verifiable via on-site or third-party inspection before payment.
Heavy-Duty Application Scenarios
Earthmoving & Site Preparation
In large-scale residential and industrial site development, this digger achieves 220-250 bank cubic meters per hour when paired with a 1.1 m³ heavy-duty bucket. The auto power boost function increases hydraulic pressure by 8% for 8 seconds when penetrating compacted clay or caliche layers, reducing cycle times by up to 12% compared to standard mode.
Quarry & Aggregate Loading
Equipped with a rock bucket and bolt-on wear strips, the 320D2 excavator loads 20-25 ton rigid dump trucks in 3-4 passes. The advanced swing damping system minimizes load swing at the dump point, reducing material spillage and truck waiting time. Many quarry operators report 8,000-10,000 operating hours between major undercarriage rebuilds under proper maintenance schedules.
Municipal Infrastructure & Utilities
For trenching for water mains, sewer lines, and telecommunications ducts, the optional 2D grade control system (available for retrofit) ensures accurate depth and slope without survey stakes. The compact tail swing radius of 2,150 mm allows safe operation near existing structures and temporary shoring systems. Machine weight under 21 tons also enables transport on standard low-bed trailers without overweight permits in most jurisdictions.
Equipment Q&A
Q1: What is the lead time for container shipping to West Africa or Southeast Asia?
A1: From our Dubai consolidation yard, 20-25 days for LCL (less than container load) shipments via direct liner service to Lagos, Tema, Jakarta, or Ho Chi Minh City. Full 40-foot high-cube containers can be loaded within 7 working days after deposit confirmation. RoRo vessel shipping for 5+ units takes 30-35 days with weekly departures from Jebel Ali Port. We provide real-time vessel tracking and destination port clearance documentation (commercial invoice, packing list, bill of lading, and COO).
Q2: What wear parts are included with the purchase?
A2: Each used digger comes with one complete set of aftermarket wear parts (4 track pads, 2 sets of bucket teeth & adapters, full set of hydraulic hose assemblies, engine oil & fuel filters, and 20 liters of genuine CAT hydraulic oil). For clients requiring 12-month consumable packages, we can pre-load a second container with undercarriage parts (rollers, sprockets, track chains) at 15% below global distributor pricing.
Q3: Does the 1-Year Global Warranty cover on-site repairs outside the seller's country?
A3: Yes. Through our network of 187 authorized service centers in 62 countries (including branch offices in Nigeria, Kenya, Chile, Indonesia, and Kazakhstan), the warranty covers parts and labor for any manufacturing defect or premature failure of the engine, main hydraulic pump, swing motor, travel motors, and main control valve. Warranty response time is 48 hours maximum for diagnostic dispatch. Extended warranty up to 36 months is available for an additional 8% of machine value.
Q4: Can you provide emission-compliant machines for EU or California projects?
A4: Absolutely. Our inventory includes 320D2 units originally delivered with EU Stage IIIB or EPA Tier 4i configurations. For markets requiring low-hour (under 3,000 hours) Tier 4 Final machines, we offer a separate certified line of used CAT 320E and 320F models. All emission certificates (EC Declaration, EPA label, China MEE) are provided digitally before vessel departure. No modifications or add-on DPF retrofits are needed – machines arrive fully compliant and ready for site registration.
Q5: What training or documentation do first-time excavator buyers receive?
A5: Every shipment includes a digital operator’s manual in English, French, Spanish, Arabic, and Bahasa Indonesia, plus a full parts catalog with OEM numbers. For buyers of 3+ units, we provide a 2-day virtual commissioning session via video link covering: (a) daily inspection walkaround, (b) hydraulic quick-coupler safety checks, (c) telematics system configuration, and (d) common fault code diagnosis. On-site training can be arranged at $850 per day plus travel.
