新しいShanding SD20U ミニエキスカベータ

The SD20U is a compact crawler excavator with an operating weight of approximately 1920 kg. It is equipped with a 3TNV70 three-cylinder water-cooled diesel engine, delivering a rated power of 10 kW / 13.6 PS at a rated speed of 2200 rpm, paired with a hydraulic drive system of around 22 kW.
Featuring a compact structure and narrow body width, it operates flexibly on confined construction sites, rural roads, during yard renovation, in orchards, nurseries, landscaping projects, small earthworks, and other restricted indoor and outdoor workspaces.

The travel system adopts a crawler chassis with a standard dozer blade. The track width is about 280 mm, standard track ground contact length roughly 1500 mm, track gauge approx. 1200 mm, and minimum ground clearance around 145 mm. Thanks to its small turning radius and low-profile body, the machine easily passes through narrow passages, gateways and woodland working zones, boosting site adaptability while maintaining stable operation.

In terms of working performance, the SD20U comes with a long boom and arm configuration: standard boom length approx. 1600 mm, arm length approx. 900 mm, maximum digging radius approx. 3380 mm, maximum digging depth approx. 2050 mm, and maximum dumping height approx. 2100 mm.
The boom can swing side-to-side with a swing angle of 51° to the left and 58° to the right, making it ideal for working close to walls, trench edges and obstacles. With a bucket capacity of 0.04–0.05 m³ and strong digging force, it handles soil excavation, trench cleaning, foundation trimming, material handling and light demolition tasks efficiently.

The hydraulic system uses load-sensing or fixed-displacement hydraulic configuration. The main pump provides sufficient flow for fast movement and well-coordinated combined actions.
The system working pressure ranges from 21–27 MPa. Operators can switch working modes for different conditions to balance digging efficiency and fuel economy.
The radiator and cooling system are optimized to maintain stable oil temperature during long continuous operations, suitable for high-temperature summer environments and extended construction work.

The SD20U supports quick change of various attachments, including standard buckets, narrow buckets, hydraulic breakers, grapples, augers, cleaning buckets and more.
By switching attachments rapidly, the machine can perform breaking, drilling, material grabbing, dredging, landscaping and farmland preparation.
It truly achieves multi-functionality with one machine, cutting equipment investment costs and improving construction efficiency.

It covers a wide range of applications, mainly including rural road maintenance, small earth excavation, farmland water conservancy renovation, orchard digging and soil loosening, nursery projects, landscaping, yard renovation, small municipal works, cable and water pipeline trenching, foundation cleanup, indoor demolition, yard material sorting, river dredging and small building construction.

For construction projects with limited access and tight space yet requiring solid excavation capacity, the SD20U is an ideal choice balancing compact dimensions, reliable performance and low operating costs.
