3.5-Ton Small Excavator

This 3.5-ton excavator, with its excellent environmental performance and precision operation capabilities, has become an ideal choice for small-scale engineering projects, municipal maintenance, and agricultural transformation. It meets the Euro 5/EPA4 emission standards and is equipped with a KUBOTA D1703 engine (with an optional Briggs & Stratton gasoline engine). Featuring a 3-cylinder in-line water-cooled 4-stroke design with a displacement of 1.642L, it delivers an output power of 18.5kw (25HP) and a rated speed of 2200rpm, with a maximum torque of 97.4N.m/1500rpm. It provides stable power output and outstanding fuel efficiency, balancing environmental protection and performance.

In terms of operating range, it demonstrates impressive flexibility and coverage. With a maximum digging height of 4800mm, a maximum digging depth of 3208mm, a maximum vertical digging depth of 2957mm, and a maximum digging distance on the ground of 5480mm, combined with a 0.12m³ standard bucket, a maximum bucket digging force of 30.4KN, and an arm digging force of 18.2KN, it can easily handle tasks such as deep foundation pit digging, slope trimming, and precision operations. The boom can swing left/right by 55°/65°, with a minimum swing radius of only 2530mm and a tail swing radius of 860mm, allowing for flexible turning even in narrow rural courtyards or municipal alleys to avoid colliding with obstacles.

The body design balances stability and passability. With an overall weight of 3810kg, a track gauge of 1420mm, and 300mm-wide steel track shoes, it has a ground pressure of 32Kpa, exerting low pressure on the ground, making it suitable for operations in sensitive areas such as farmland and lawns. Each track is equipped with 1 carrier roller and 4 supporting rollers, combined with 2×0.7L final drives, ensuring stable and reliable travel. It can reach speeds of 14.2km/h (high) and 4.4km/h (low) and has a maximum grade ability of 58% (30°), enabling unimpeded movement across complex terrains.

Its auxiliary operation functions are equally excellent. The blade, with a height of 350mm, has a maximum lifting height of 365mm and a maximum cutting depth of 385mm, allowing for quick site leveling and residual soil cleaning, reducing the need for auxiliary equipment. The hydraulic system, with a pressure of 22.5Mpa, responds sensitively, ensuring high precision in bucket operations. Coupled with a swing speed of 12rpm, it achieves efficient and smooth operation cycles.

The cab is designed with user-friendliness in mind, offering a wide field of vision and lightweight, labor-saving operation levers, which reduce fatigue during long working hours. The 40L fuel tank and 44L hydraulic oil tank meet the needs of all-day continuous operation; with an engine oil capacity of 7L and a radiator capacity of 3.8L, maintenance is convenient. With overall dimensions of 4915mm×1720mm×2525mm and a minimum ground clearance of 295mm, it is flexible for transportation and transfer. Whether it is precision digging for pipeline laying or earthwork sorting for orchard transformation, it can provide efficient support for diverse scenarios with its "small yet sophisticated" characteristics.
