Used Caterpillar 320D2L Crawler Excavator for International Construction

Procuring a heavy-duty used Caterpillar 320D2 crawler excavator provides large-scale civil engineering contractors, quarry managers, and infrastructure developers with an exceptionally dependable earthmoving platform. Weighing 21,100 kg, this mid-sized commercial excavator is globally recognized for balancing aggressive digging forces with long-term mechanical reliability. By sourcing a fully inspected pre-owned model, overseas purchasing teams acquire factory-grade operational performance while dramatically lowering machinery capital outlay. Our specialized yard performs comprehensive technical assessments, fluid analysis, and mechanical reconditioning on every unit to ensure seamless deployment across demanding job sites.

Advanced Hydraulic Engineering and Core Structural Design

Every second-hand earthmoving unit in our collection passes through rigorous mechanical inspections conducted by heavy equipment technicians to verify compliance with OEM operational thresholds.

Cat C7.1 ACERT High-Efficiency Powertrain

At the center of this 21.1-ton excavator lies a genuine Cat C7.1 ACERT engine. Featuring a 6-cylinder, water-cooled layout with a 7.01L displacement, this powertrain delivers a rated output of 112 kW at 1800 rpm. Designed specifically to manage variable fuel quality across international markets, the mechanical fuel injection system reduces maintenance frequency while providing reliable high-torque delivery under continuous heavy load conditions.

Precision Hydraulic Control and Excavation Power

The hydraulic system utilizes original Cat main pumps and distribution valves configured to generate a bucket digging force of 125 kN and a stick digging force of 104 kN. Driven by a 5700 mm boom and a 2900 mm stick, the unit achieves a maximum excavation depth of 6720 mm and a maximum excavation radius of 9850 mm at ground level. These hydraulic metrics allow operators to maintain rapid trenching and loading cycles in dense clay, compacted gravel, or blasted rock.

Robust Undercarriage and Travel Dynamics

Constructed on a heavy-duty steel track chassis, the machine features a walking speed of 5.4 km/h and a rotation speed of 10.9 rpm for quick repositioning along cut slopes. With a 35°/70° gradeability rating and a 410L fuel capacity, the machine maintains stable traction across steep embankments and soft terrain during extended work shifts.

Commercial Field Application Scenarios

Commercial Infrastructure and Mass Earthmoving

With a standard 1.0 m³ bucket capacity and a maximum unloading height of 6490 mm, this excavator excels in loading high-capacity haul trucks. The 112 kW engine output ensures steady production rates during commercial foundation digging, site grading, and bulk material transfer.

Deep Utility Trenching and Pipeline Layouts

Reaching a maximum vertical excavation depth of 5690 mm, the equipment easily accommodates municipal drainage projects, deep utility trenching, and pipeline installations. The smooth hydraulic distribution valves allow precise placement of shoring boxes and heavy concrete pipes.

Quarrying and Road Reconstruction Work

The 125 kN bucket digging force coupled with reinforced track links makes this machine suitable for harsh aggregate quarries and highway construction projects. The heavy steel undercarriage absorbs high-impact stresses encountered when handling shot rock or breaking up asphalt pavements.

Customization, Maintenance, and Export Logistics Support

We offer comprehensive pre-delivery preparation to meet specific commercial site requirements and international import standards.

• System Pressure Calibration: Our mechanics test hydraulic pump pressures, calibrate control valves, and replace worn seals to maintain factory operating speeds.

• Engine and Fluid Servicing: Every unit receives new oil and air filters, clean engine oil, radiator flushing, and fuel line inspections prior to export.

• Attachment retrofitting: We can equip the machine with auxiliary hydraulic lines to support hydraulic breakers, quick couplers, or heavy-duty rock buckets.

• Global Shipping Coordination: Equipment is prepared for ocean transit via Flat Rack containers or Roll-on/Roll-off (RoRo) shipping, accompanied by complete bill of lading and export clearance documentation.

Frequently Asked Questions (FAQ)

How do you verify the hydraulic pressure and pump condition on used units?

Our technical staff connects pressure gauges directly to the Cat main hydraulic pump to verify that output pressures meet original performance specifications. We test all cylinder stroke speeds and verify distribution valve response under full operational load.

Is the Cat C7.1 ACERT engine compatible with variable diesel fuel grades?

Yes, the Cat C7.1 ACERT engine integrated into the 320D2 series is designed to handle varying fuel quality levels common in international markets. We inspect the fuel system and replace primary and secondary filtration components before shipment.

What third-party inspection options are available prior to purchasing?

Buyers are welcome to assign independent inspection firms (such as SGS or Bureau Veritas) to evaluate the unit at our yard. Inspectors can perform engine blow-by tests, hydraulic pressure checks, and undercarriage wear measurements.

What are the exact shipping dimensions for freight transport calculation?

The transport dimensions are 9460 mm in length, 2800 mm in width, and 3030 mm in height, with a total operating weight of 21,100 kg. These dimensions allow for containerized flat-rack shipping or standard RoRo transport.

What payment terms do you accept for international machinery orders?

We process international transactions via standard Telegraphic Transfer (T/T). Orders are secured with an initial commercial deposit to begin servicing and freight packing, with the remaining balance cleared upon presentation of export documents and the Bill of Lading.
