SE35

Product Overview

The SE35 is a 3.5-ton steel-track mini excavator powered by a 34 kW (46.24 hp) Changchai 4-cylinder water-cooled diesel engine, offering a max digging depth of 2,500 mm and a bucket capacity of 0.1 m³. It is widely used for trenching, pipe laying, foundation digging, greenhouse construction, and landscaping projects in narrow urban sites, orchards, and mountainous areas. As a direct factory supplier, we provide full customization (bucket size, rubber/steel track option), 2-year warranty, and timely global delivery, ensuring reliable performance and low operating costs for contractors and equipment rental companies.

Detailed Advantages 

1. High digging efficiency in compact dimensions

With a maximum digging depth of 2,500 mm, vertical digging depth of 2,350 mm, and digging radius of 4,100 mm, the SE35 outperforms many similar 3.5-ton class excavators in its size range. The 0.1 m³ bucket and 450 mm bucket width are specifically designed for narrow trenching, pipe laying, and foundation work in urban or confined job sites where larger machines cannot enter. The optimized hydraulic system provides smooth, precise control for both digging and backfilling, reducing cycle time and improving daily work output on residential construction, road repair, and landscaping projects.

2. Stable and durable under tough conditions
Heavy-duty steel tracks offer superior ground grip, impact resistance, and long service life even on rocky or uneven terrain. The machine’s overall width of 1,500 mm and compact dimensions (3,960×1,500×2,400 mm) allow easy access through standard garden gates, narrow alleys, or building openings. A gradeability of 35° ensures safe and stable operation on slopes and soft ground, reducing rollover risk and increasing operator confidence. The reinforced undercarriage and track frame minimize downtime caused by debris or rough site conditions, making the SE35 a reliable choice for rental fleets and daily construction use.

3. Operator-friendly & low-maintenance design
The standard weather-protected cab improves all-weather working comfort, reducing operator fatigue during long shifts. The 4-cylinder water-cooled Changchai engine (34 kW / 46.24 hp) delivers reliable power with moderate fuel consumption, supported by a widely available spare parts network. Routine service points — including oil filler, fuel filter, and air cleaner — are grouped and easily accessible through the side cover, enabling fast daily checks and reducing maintenance time. An included tool kit covers common on-site repairs, and the 2-year warranty provides additional peace of mind, lowering your total cost of ownership over the machine’s lifetime.

Application Scenarios

1.Urban Trenching & Utility Line Installation Scenario: Laying water pipes, gas lines, or electrical conduits along narrow city streets or between buildings. Performance: With a bucket width of 450 mm and overall machine width

of 1,500 mm, the SE35 easily fits through standard gateways and tight alleyways. The 2,500 mm max digging depth reaches standard utility trench depths, while the 0.1 m³ bucket provides precise excavation without

damaging adjacent foundations. The compact tail swing reduces collision risks in congested sites.

2. Residential Foundation & Basement Digging Scenario: Excavating small building foundations, basements, or retaining wall footings on housing projects. Performance: The 2,350 mm vertical digging depth allows straight, clean cuts near walls. The 35° gradeability ensures stable operation on sloping or uneven residential lots. The steel tracks provide firm grip on compacted soil or clay, and the cab improves all-day operator comfort during repetitive digging cycles. 

3. Landscaping & Greenhouse Construction Scenario: Shaping garden ponds, planting large trees, or leveling ground inside greenhouses and nurseries. Performance: The 3,850 mm max digging height reaches over greenhouse frames, and the 2,600 mm dumping height easily loads soil into trucks or trailers. The 4,100 mm digging radius covers wide areas without frequent repositioning, saving time on soft ground where repeated tracks may cause ruts. Light weight (3,500 kg) minimizes ground compaction. 

4. Roadside Drainage & Slope Maintenance Scenario: Cleaning or digging roadside ditches, culvert trenches, or slope stabilization work. Performance: The 35° gradeability allows safe operation on embankments and roadside slopes. The 450 mm narrow bucket precisely shapes V-ditches, while the 2,500 mm depth handles standard drainage requirements. The water-cooled Changchai engine (46.24 hp) delivers sustained power even during long uphill digging sessions without overheating. 

5. Small Demolition & Material Handling Scenario: Breaking concrete walkways, removing small structures, or loading demolition debris. Performance: The steel tracks resist damage from broken concrete and rebar. The 2,600 mm dumping height can load directly into 3-5 ton dump trucks. The 0.1 m³ bucket capacity balances material handling efficiency with machine stability. Optional hydraulic accessory lines (if equipped) can power a breaker or auger — though not listed, the 34 kW engine provides sufficient auxiliary flow for light attachments.

6. Agricultural & Orchard Work Scenario: Digging irrigation channels, cleaning animal waste lagoons, or installing fence posts on farms. Performance: Compact dimensions (3,960×1,500×2,400 mm) allow maneuvering between tree rows or inside barns. The 2-year warranty and included tool kit reduce farm maintenance costs. The simple, mechanical engine (Changchai) is easy to service in rural areas without specialized diagnostic tools.
