3 ton mini excavator
1、3-ton mini excavator: efficient for small/medium projects.
2、3-ton weight: balances flexibility/load; compact, fits narrow spaces (rural, infrastructure, municipal).
3、Handles more than smaller models; suits medium/high-intensity work.
4、High-power engine: strong, fuel-efficient; water-cooled for long, intense runs.
5、Scientific tracks: low ground pressure (safe for lawns/tiles); easy to operate, multi-attachment compatible.
6、Better digging radius/depth vs smaller models; stable hydraulics: high efficiency.
7、Reinforced parts: durable; easy maintenance, low costs: balances flexibility/efficiency.
The WK30 3-ton crawler mini excavator is a high-efficiency equipment specially designed for medium and high-intensity small and medium-sized projects. With the dual advantages of "flexible size + heavy load capacity", it has become a core equipment in scenarios such as rural renovation, municipal engineering, and small-scale infrastructure construction. Its optimized body design achieves a perfect balance between performance and passability. With an overall length of 3074mm, an overall width of 1500mm, and an overall height of 2450mm, it can easily navigate through confined spaces such as narrow lanes and construction sites. Meanwhile, compared to smaller-tonnage models, it has stronger load-bearing capacity and can easily meet the needs of medium and high-intensity operations.
The power system is equipped with a Kubota engine, which delivers strong and stable power output. Combined with scientific fuel injection technology, it ensures operational efficiency while taking into account fuel economy. The equipment's travel speed is divided into two gears: 3.1km/h and 2km/h, which can be flexibly switched according to scenarios — the fast gear is suitable for long-distance transfers, and the slow gear is suitable for precision operations. The rotation speed of 12r/min and the 360° full rotation function make the operation more flexible and precise, allowing easy adjustment of the working angle even in complex sites. The maximum climbing gradient of 30° endows it with the ability to cope with gentle slope terrain, further expanding the operating range.
In terms of operational performance, the WK30 demonstrates a coverage range and power far exceeding those of peer models: the 0.075m³ bucket capacity is significantly improved compared to smaller-tonnage models, reducing the number of material transfers and greatly improving construction efficiency. The maximum digging depth reaches 2570mm, and the maximum digging radius is 4358mm. Combined with a maximum digging height of 3453mm and a maximum dumping height of 2366mm, it can easily complete various tasks such as wall foundation excavation, deep ditch trimming, and material loading. The minimum turning radius of 883mm is extremely small, eliminating the need for frequent machine movement when operating in narrow spaces. Coupled with flexibly adjustable working angles, it further improves operational efficiency.
The detailed design of the equipment takes both practicality and durability into account: the optimized design of track width and length ensures reasonable ground pressure, allowing it to work on fragile surfaces such as lawns and floor tiles without causing damage. The bulldozer has a maximum digging depth of 291mm and a maximum raising height of 192mm, which can not only quickly level the site but also assist in stabilizing the equipment during operation, improving overall construction efficiency. Reinforced structural components and a precision hydraulic system (with implicit stable pressure characteristics) ensure precise and controllable operations. When paired with attachments such as breakers and grapples, it can be expanded to multiple processes including crushing, grabbing, and loading, truly realizing "one machine for multiple uses". Daily maintenance only requires basic inspection and lubrication, significantly reducing operating costs and providing an efficient and economical comprehensive solution for small and medium-sized projects.
