3.5 ton mini excavator

    The 3.5-ton excavator, with "all-round efficiency" as its core advantage, has become a mainstay in small and medium-sized engineering projects thanks to its balanced design of powerful performance and flexible operation. It is equipped with a KUBOTA D1703 engine that meets both Euro 5 and EPA4 emission standards. Featuring a 3-cylinder in-line water-cooled 4-stroke structure with a mechanical pump and natural aspiration, it delivers an output power of 18.5kW (25HP) and a stable rotation speed of 2200rpm. With a maximum torque of 97.4N.m (at 1500rpm) and a displacement of 1.642L, it ensures sufficient power and fuel economy even during heavy-load operations. Additionally, a Briggs & Stratton gasoline engine is available as an alternative to meet fuel preferences and usage scenarios in different regions.

It excels in passability and flexibility: with an overall dimension of 4915mm×1720mm×2525mm, 300mm-wide steel track shoes, and a track gauge of 1420mm, along with a ground contact length of 1670mm, it not only guarantees stability on hard surfaces but also provides ample grip on soft terrain. The configuration of 295mm minimum ground clearance, 4 supporting rollers, and 1 carrier roller per side allows it to easily handle complex road conditions such as gravel and slopes. The 860mm tail swing radius and 2530mm minimum turning radius enable the equipment to maneuver flexibly in confined spaces like near walls and buildings, significantly reducing the risk of collisions.

Its operational performance covers diverse scenarios: the maximum digging depth reaches 3208mm, and the maximum vertical digging depth is 2957mm, making it capable of deep operations such as foundation excavation and pipeline laying. The maximum digging height of 4800mm and maximum dumping height of 3406mm meet the needs of material stacking and loading. The maximum ground digging radius of 5480mm expands the operation range, and combined with the 55° left and 65° right boom swing angles, it enables more efficient work in corner areas. The standard 0.12m³ bucket, along with a maximum digging force of 30.4kN, ensures smooth excavation in hard soil. The 12rpm swing speed and 22.5Mpa hydraulic system pressure ensure precise and coordinated composite movements.

The equipment is also equipped with practical auxiliary functions: the blade can achieve a maximum lifting height of 365mm and a maximum cutting depth of 385mm, facilitating site leveling and foundation cleaning. The dual-speed travel (14.2/4.4km/h) balances transfer efficiency and operational safety. Through a quick-change interface, it can switch between attachments such as breakers and grapplers, easily handling tasks like crushing, tree planting, and material handling. Whether it is municipal engineering, agricultural transformation, or small-scale mining operations, this 3.5-ton excavator can create sustainable value for users with its balanced performance and wide adaptability.
