Product Summary
The 0.3m³ bucket Excavator (model XE35U / equivalent to Kubota U35) is engineered for high-density urban infrastructure, narrow trenching, and agricultural drainage. With a 3,580 kg operating weight and a 22.1 kW diesel engine, this compact digger delivers breakout forces of 23.5 kN (bucket) and 18.7 kN (arm). Its zero-tail-swing design meets Tier 3 / Stage V emission standards for global import compliance. All units undergo a 48-hour factory burn-in test before RORO or container stuffing.
Why Choose This Machinery
Compared to standard 1.5-2 ton micro excavators, the 0.3m³ class provides 35% higher bucket fill factor in clay and compacted gravel. The reinforced X-shaped undercarriage with 300 mm steel tracks reduces ground pressure to 32 kPa, enabling operation on soft terrain without sinking. Fuel efficiency averages 3.8 L/h, lowering total cost of ownership (TCO) by 18% over 5,000 hours. The 1-year global warranty covers the powertrain, main hydraulic pump, and rotary union, with a genuine spare parts kit (filters, seals, teeth) included for the first 1,000 hours of operation. Buyers benefit from direct factory pricing and consolidated 40ft HQ container loading (4 units per container) or break-bulk RORO for single units.
Powertrain & Structural Overview
Power comes from a liquid-cooled, indirect injection diesel engine (Cummins/Isuzu lineage) producing 22.1 kW at 2,200 rpm, with a high-torque reserve of 15% at 1,800 rpm. The hydraulic system uses a tandem variable-displacement piston pump (64 L/min main flow) plus a gear pump for pilot control, delivering precise feathering for pipe laying. The fully enclosed ROPS/FOPS cab includes adjustable wrist rests, a 4.3-inch LCD monitor, and an auxiliary hydraulic line (45 L/min) for breakers or augers. The boom and arm are fabricated from Q345B high-strength steel with a 6 mm plate thickness, double-welded and stress-relieved. Swing torque is 19.5 kN·m, and dozer blade lift force reaches 21.2 kN.
Technical Specifications
Below is the primary data for the 0.3m³ excavator. All values are based on ISO 9249 and SAE J1176 standards.
Heavy-Duty Application Scenarios
Earthmoving & Trenching
Excavate 2.5 m deep foundation trenches (max digging depth 3.1 m). The offset boom rotates 60° left and 55° right, allowing wall-side digging within 200 mm clearance. Ideal for residential lot grading and utility line installation.
Quarry & Demolition Support
Equipped with a hydraulic quick coupler and a 350 kg breaker (optional), the 0.3m³ excavator breaks concrete slabs up to 200 mm thick. The reinforced front linkage withstands high-frequency impact for secondary reduction tasks.
Municipal & Landscaping
Zero-tail-swing and 1,580 mm tail radius allow safe operation next to live traffic. The low-noise mode (96 dB(A) external) meets urban noise ordinances. Use the dozer blade for fine grading and backfilling after pipe placement.
Equipment Q&A
Q1: What are the shipping lead times and available transport methods for the 0.3m³ excavator?
A: For stock units (standard yellow paint), lead time is 7-10 working days after deposit. You can choose 40ft HQ container loading (4 units per container) or RoRo for single units. For break-bulk or non-standard attachments, lead time extends to 20-25 days. All export packaging includes anti-rust oil, plastic wrapping, and steel strapping.
Q2: What spare parts are included, and how quickly can genuine parts be delivered globally?
A: Each unit ships with a 1,000-hour wear parts kit (air filter, fuel filter, oil filter, 5 x bucket teeth, and track adjusting grease). Genuine spare parts are stocked at our regional hubs in Dubai, Panama, and Singapore, with 3-5 day express delivery to major ports. A full rebuild kit (cylinders, pump, seals) is available within 10 working days.
Q3: Does the 0.3m³ excavator meet international emission standards for customs clearance?
A: Yes. The engine is certified to EU Stage V (Diesel) / EPA Tier 4 Final via a DOC+DPF configuration (standard for EU/US markets). For markets with less stringent requirements (Africa, South America, Southeast Asia), we offer a Tier 3 equivalent mechanical engine (no DPF, lower initial cost). A valid CO (Certificate of Origin) and emission compliance declaration are provided with every shipment.
Q4: How does the 1-year global warranty work for remote sites without local dealers?
A: The warranty covers all structural and powertrain components (engine block, main hydraulic pump, swing motor, track frame). If a covered failure occurs, we ship the replacement part via air freight (DDP terms) within 48 hours and provide an online repair video guide. For multiple-unit buyers, we offer a free one-week on-site training/inspection visit within the first six months.
Q5: Can this machine be fitted with a long arm or extra counterweight for deep excavation?
A: Yes, optional 2.9 m long arm (standard is 1.6 m) increases maximum digging depth to 3.8 m, though bucket capacity reduces to 0.22 m³ to maintain stability. Alternatively, an additional 180 kg bolt-on counterweight allows the standard arm to handle 0.3 m³ full buckets at a 4.0 m reach.
