Product Summary
This High Efficiency Excavator (Model: HEE-350LC) represents a breakthrough in fuel-to-hydraulic conversion efficiency. With an operating weight of 35,000 kg and a net power of 260 hp (194 kW), the machine achieves a 9% lower specific fuel consumption compared to previous generation 35-tonners. The closed-center hydraulic system delivers 320 L/min main pump flow, enabling cycle times as fast as 18 seconds for a 90-degree truck loading swing. Built for exporters, this unit is fully compliant with Tier 3 / Stage V (EU) emission standards and supports both Roll-on/Roll-off (RoRo) and 40' flat rack container shipping.
Why Choose This Machinery
Unlike standard Chinese or reconditioned Japanese excavators, the HEE-350LC combines OEM-level precision with export-specific advantages. Fuel efficiency: variable displacement axial piston pumps reduce fuel burn to 21 L/hour under average load. Undercarriage robustness: triple-flange track rollers, 600 mm triple-grouser pads, and a reinforced D-section track frame provide 15% longer wear life in rocky terrain. Global procurement drivers: we maintain a $2.3M spare parts warehouse near Shanghai Port, ensuring genuine filters, pins, bushings, and hydraulic components ship within 48 hours. Each excavator includes a 1-Year Global Warranty covering powertrain and main hydraulic components, with optional on-site commissioning by our regional service partners.
Powertrain & Structural Overview
Under the hood, the Cummins QSB6.7 (or equivalent Isuzu 6HK1 for certain markets) features a high-pressure common rail system and a viscous damper to reduce torsional vibrations. The cooling package is desert-spec with a hydraulically driven fan that reverses automatically every 30 minutes. The main control valve uses LUDV (Load Independent Flow Distribution) technology, ensuring precise boom, arm, and bucket coordination even at low engine RPM. The cab offers ROPS/FOPS Level 2 certification, an 8-inch LCD monitor with fuel consumption telemetry, and an optional air-suspension seat. For heavy-duty export markets, we upgrade the swing bearing to a double-row ball race with induction-hardened raceways.
Technical Specifications
Below is the primary data for the High Efficiency Excavator Model HEE-350LC. All parameters are tested under ISO 9249 and SAE J1349 standards.
Heavy-Duty Application Scenarios
Earthmoving & Bulk Excavation
The 1.8 m³ heavy-duty bucket with bolt-on wear strips and a 9.2 m maximum digging reach makes the HEE-350LC ideal for highway subgrade preparation and large-scale residential site development. Combined with a quick coupler, operators can switch to a 2.2 m³ light material bucket for soil or coal.
Quarrying & Rock Handling
Fitted with a 1.4 m³ rock bucket (20 mm HARDOX liners) and a top guard for the cab, this excavator breaks and loads blasted limestone, granite, or basalt at up to 250 tons per hour. The reinforced boom and arm have 20% thicker belly plates than standard 35-ton units.
Municipal & Infrastructure
With optional rubber pads on the track shoes and a reduced tail swing (2.95 m radius), the HEE-350LC can operate on finished asphalt or in urban trenching projects. The ECO mode reduces fuel consumption by an additional 12% for light-duty pipe laying and backfilling.
Equipment Q&A
Q1: What is the current shipping lead time for a trial order of one unit?
A1: For a single High Efficiency Excavator, we can dispatch within 15-20 days after receiving the deposit. RoRo shipping from Shanghai or Tianjin port to major hubs like Durban, Santos, or Houston takes approximately 30-45 days. For container shipping (disassembled cab and counterweight), we add 5 days for crating.
Q2: Do you supply a standard wearing parts package with the machine?
A2: Yes. Every HEE-350LC includes a complimentary 2,000-hour wearing parts kit: two sets of track pads, one set of bucket teeth and adapters, primary and secondary fuel filters, engine oil filters, hydraulic return filter, and a set of swing bearing grease seals. Additional kits are available at 8% below retail for bulk buyers.
Q3: Which emission standard does this excavator meet? Can it be imported to the EU or California?
A3: The standard configuration meets China Stage III / EU Stage V (non-road) equivalent to EPA Tier 3. For regions requiring Tier 4 Final or Stage V with DPF, we offer a variant with a Cummins QSB6.7 + DOC + EGR system. Please specify your local emission requirements before ordering.
Q4: Is operator training or technical documentation provided?
A4: Absolutely. We supply a full digital service manual, parts catalog, and operator handbook in English, Spanish, French, or Arabic (PDF + printed). Optional 3-day on-site operator and maintenance training can be arranged through our local dealer network for an additional $1,850 plus travel.
Q5: How do you handle warranty claims for an exported machine?
A5: Our 1-Year Global Warranty covers engine, main pumps, swing motor, travel motors, and the main control valve. For approved claims, we ship replacement parts via DHL Express (3-5 days) at our cost. Labor is reimbursed at a pre-agreed rate ($65/hour) to your local workshop after remote diagnosis by our engineers.
