Inspected Used Hitachi ZX70-5A Excavator for Commercial Fleet Upgrades

Purchasing a used Hitachi ZX70-5A excavator provides international construction contractors, utility companies, and equipment distributors with a highly durable, cost-effective earthmoving solution. This 6.7-ton crawler excavator is designed to deliver stable performance across a wide array of municipal, agricultural, and civil engineering tasks. Backed by extensive field inspections and verified components, our commercial export fleet units offer reliable power systems, highly responsive hydraulics, and robust structural integrity. International procurement managers can acquire this premium machinery with complete technical transparency, ensuring low downtime and maximum return on investment for their operations.

Core Structural and Engineering Advantages

Our commercial machinery undergoes meticulous physical verification to confirm that vital mechanical assemblies perform to their designated factory specifications.

High-Output Japanese Powertrain

This unit features an original, heavy-duty 4TNV98 engine, running a 4-cylinder water-cooling system with a substantial 3.318L displacement. Generating a rated power of 42.4kw at 2100rpm, this highly efficient engine provides consistent high-torque delivery under continuous digging loads. The mechanical fuel injection and cooling layouts are built for prolonged daily shifts, ensuring that fleet operators experience straightforward field maintenance and stable power delivery.

Kawasaki Hydraulic Integration

Operating with a premium Kawasaki hydraulic pump and a matching Kawasaki distribution valve, the hydraulic control system ensures exceptionally smooth compound movements. The machine delivers a strong bucket digging force of 55KN and a stick digging force of 38KN. This high-efficiency fluid power synchronization allows operators to slice through highly compacted soils and clay without facing engine stall or hydraulic pressure drops.

Rugged Undercarriage and Mobile Capability

Built on a heavy-duty crawler frame with an operating weight of 6700kg, this model balances powerful ground-level stability with easy transport logistics. Featuring a walking speed ranging from 3.4 to 5.0km/h and a maximum gradeability of 35°/70°, the machine moves efficiently across steep inclines, mud-slicked terrains, and rocky job sites, minimizing repositioning delays.

Verified Technical Parameters

The technical data shown below is transcribed directly from the physical machine specification plates and verified through our multi-point inspection process.

Practical Commercial Application Scenarios

Municipal Infrastructure Development

The overall transport width of 2260mm makes this machine highly suitable for tight urban corridors. Contractors can perform utility trenching down to a maximum vertical excavation depth of 3730mm, laying fiber-optic cables, water mains, and gas lines without blocking adjacent lanes of public traffic.

Residential Foundation and Earthmoving Projects

Featuring a versatile bucket capacity range of 0.33-0.38m³, this machinery excels at clearing soil, loading light aggregates, and preparing basement foundations. Operators can load standard tandem-axle dump trucks efficiently, utilizing the maximum unloading height of 5060mm to speed up site preparation timelines.

Large-Scale Agricultural Land Reclamation

For farms, orchards, and agricultural cooperatives, the machine's 42.4kw engine power makes light work of clearing drainage ditches, leveling land, and removing tree stumps. The durable undercarriage tracks prevent excessive soil compaction while maintaining steady traction across muddy farm terrain.

International Shipping, Inspection, and Customization Services

We provide comprehensive export-ready services designed to simplify international heavy machinery procurement for overseas business entities.

• Rigorous Inspection Protocol: Every pre-owned excavator undergoes physical validation, including structural weld integrity testing, hydraulic pump pressure tests, and engine load cycle assessments.

• Customization Options: We can fit the hydraulic arm with specialized lines and supply optional attachments, including hydraulic breakers, quick-couplers, sorting grabs, and customized trenching buckets.

• Preventative Fleet Maintenance: Before container or vessel loading, our technicians change the engine oil, install new fuel and hydraulic filters, grease all structural pins, and clean the cooling radiator.

• Professional Export Logistics: We coordinate secure shipping arrangements via Flat Rack, High Cube (40HC) containerization, or roll-on/roll-off (RoRo) ocean transport to your designated port, providing all essential bills of lading, commercial invoices, and export clearance documents.

Frequently Asked Questions (FAQ)

How do you evaluate the condition of the hydraulic system before export?

Our engineers connect digital diagnostic equipment directly to the Kawasaki hydraulic pump and main control valve. We measure real-time pressure outputs under full working loads to ensure they meet the factory specification of the Hitachi ZX70 series, guaranteeing that there is no internal hydraulic bypass or pressure leakage.

Can we request a live video inspection of this machine running?

Yes. For overseas buyers who cannot conduct on-site evaluations, we provide high-definition video walkthroughs. This includes a cold engine start, live undercarriage tracking, operation of the boom and arm, and a physical inspection of the cabin interior and main components.

Are replacement engine components easy to source internationally?

Absolutely. The 4-cylinder 4TNV98 engine is a globally popular platform used across multiple heavy machinery brands. Fleet managers can easily find replacement filters, gaskets, injectors, and overhaul kits through local commercial engine distributors.

What are the primary shipping arrangements for this 6.7-ton excavator?

We offer flexible logistics solutions depending on your port facilities. To minimize freight costs, we can partially disassemble the boom and cabin to fit the unit inside a standard 40-foot High Cube container. Alternatively, we ship the machine fully assembled on a flat rack or via roll-on/roll-off (RoRo) shipping.

What is the typical payment structure for wholesale orders?

For commercial export agreements, we generally operate under standard Telegraphic Transfer (T/T) terms. A partial deposit is required to lock in the machine and begin the maintenance/servicing phase, with the remaining balance settled upon loading and presentation of the draft Bill of Lading.
