Product Summary
The 40 ton crawler excavator is a high-performance mining and construction class machine with an operating weight of 42,800 kg and a bucket capacity up to 2.2 m³. Powered by a fuel-efficient Cummins QSM11 diesel engine delivering 280 kW (375 hp), it achieves breakout force of 265 kN and arm crowd force of 210 kN. The machine is designed for continuous operation in quarries, large-scale earthmoving, and heavy infrastructure projects, with a reinforced undercarriage and high-flow hydraulic system for attachments like hydraulic hammers and grapples.
Why Choose This Machinery
Compared to standard 40-ton class competitors, our model provides 12% higher fuel efficiency through an electronically controlled hydraulic load-sensing system and an auto-idle feature that reduces consumption during standby. The reinforced box-frame undercarriage extends track life by up to 3,000 hours in abrasive conditions. Total cost of ownership (TCO) is reduced by 18% over 10,000 operating hours due to extended filter change intervals (500 hours) and genuine wear parts availability from our regional warehouse. ROI accelerates within 22 months for rental fleets or mining subcontractors. We include a 1-year global warranty covering drivetrain, hydraulics, and structural components, with 48-hour parts dispatch for critical items.
Powertrain & Structural Overview
The 40 ton excavator integrates a Cummins QSM11 diesel engine (280 kW / 375 hp) with selective catalytic reduction (SCR) technology meeting EU Stage V / EPA Tier 4 Final equivalency. The variable displacement axial piston pumps deliver 2 x 280 L/min at 34.3 MPa, driving the swing motor at 11.5 rpm. The heavy-duty planetary final drives provide 65% gradeability and high travel speed of 5.4 km/h. The ROPS/FOPS certified cab features full air suspension seat, 7-inch LCD monitor with rearview camera, automatic climate control, and joystick controls with fine metering for attachment precision. The X-shaped undercarriage with three carrier rollers and eight bottom rollers per side ensures stability at maximum reach (11.9 m ground level).

Heavy-Duty Application Scenarios
Mining Overburden Removal
In coal and iron ore mines, the 40 ton excavator removes topsoil and overburden with a high-capacity 2.5 m³ light material bucket. Quick coupler compatibility allows rapid switching to ripper teeth for frozen or compacted layers.
Large-Scale Earthmoving
For highway embankments, dam construction, and airport runways, the excavator achieves 280 m³/hour production at 10 m digging depth. Grade assist and 2D machine control ready for laser or GNSS guidance improves trench accuracy by 40%.
Quarry & Aggregate Processing
Equipped with a rock bucket (1.8 m³) and reinforced belly guards, the machine feeds primary crushers and stockpiles aggregates. The optional hydraulic hammer attachment handles boulders up to 1.2 m diameter without repositioning.
Equipment Q&A
Q1: What is the exact shipping lead time for the 40 ton excavator to major ports?
We ship via RoRo or 40 ft FCL containers (machine disassembled to main body, counterweight, boom/arm components). Standard EXW lead time is 15-20 working days after deposit. Sea freight to North Europe, Middle East, or Southeast Asia takes 25-35 days. We provide daily tracking and customs documentation (ECN, COO, CE certificate).
Q2: Does the 1-year global warranty include wear parts like tracks and bucket teeth?
The 1-year global warranty covers the engine, main pumps, swing device, travel motors, control valves, and structural welds. Wear parts (bucket teeth, cutting edges, track pads, hydraulic hoses, filters) are not covered but are stocked in our Dubai, Rotterdam, and Singapore spare parts hubs for 2-day air delivery. We include one free wear parts kit (bucket teeth + filters) with each machine.
Q3: What emission standards does this 40 ton excavator meet for global export?
Our standard configuration meets EU Stage V (with DPF+SCR) and EPA Tier 4 Final. For markets like Africa, South America, or Southeast Asia without strict emission laws, we offer a de-rated Tier 3 / Stage IIIA version at lower cost and with simplified aftertreatment (no DPF). The engine serial number is fully traceable for customs clearance.
Q4: Can I get remote technical support and operational training?
Yes. Each machine includes 4 hours of online classroom training for your lead operators (via Zoom/Teams) covering daily inspections, hydraulic troubleshooting, and fuel efficiency practices. We also provide a full PDF service manual and parts catalog. For fleet buyers (5+ units), we can send a field service engineer to your site for 3 days onsite training (travel cost covered by buyer).
Q5: What is the financing or leasing option for B2B exporters?
For registered construction companies or rental firms, we offer direct leasing through our finance partners with 20% down payment and 12-24 month 0% interest (subject to credit approval). Letter of Credit (L/C) at sight or 30% T/T deposit + 70% against BL copy are standard. We also accept bank transfer in USD, EUR, or RMB.
