Excavator Small Digger

If you’re searching for a versatile, durable, emission-compliant 3-ton mini excavator for limited workspaces, the DERETTE RT30 is your ultimate solution. Designed for professional contractors, equipment rental companies, farmers, and municipal engineering teams, this zero tail swing mini digger integrates Japanese premium power, intelligent digital operation, and full-scenario working adaptability. Different from conventional small excavators, the RT30 features an independent side swing boom and true zero-tail design, delivering unmatched flexibility for narrow-site construction, landscaping renovation, and farm maintenance projects worldwide.

Fully certified with Euro V, EPA Tier 4, and China National IV emission standards, this 3000kg crawler excavator requires no secondary modification or certification fees for exports to the US, Europe, Australia, Southeast Asia, and other mainstream markets. With optional enclosed air-conditioned cabin and full hydraulic attachment compatibility, the RT30 is a cost-effective, high-efficiency workhorse for all light to medium earthmoving jobs.

Premium Japanese Power & Efficient Hydraulic Performance

The entire RT30 mini excavator series is powered by authentic Japanese industrial engines, supporting two reliable options:Yanmar 3TNV80F and Kubota D1105, with a rated power of 14.6kW (19.6HP) at 2400rpm. The liquid-cooled diesel engine features low fuel consumption, low noise, strong power output, and ultra-long service life, meeting the strictest global environmental protection standards. It effectively adapts to long-hour continuous operation in high-intensity construction, farm work, and rental scenarios.

Matched with an advancedload-sensing hydraulic system with a maximum hydraulic flow of 95L/min, the machine achieves sensitive response, smooth operation, and precise control accuracy. Equipped with an automatic speed-adjustable travel motor, the RT30 realizes dual traveling speeds of 2.3km/h and 4.0km/h, with a maximum gradeability of 30° (58%). It can stably travel and operate on muddy roads, rugged slopes, and soft farmland. The 24kN bucket digging force and 14.8kN arm digging force ensure powerful excavation capacity, easily coping with hard soil digging, small concrete crushing, and stump removal work.

Zero Tail Swing + Side Swing Boom – Perfect For Confined Work Sites

The biggest competitive advantage of the DERETTE RT30 compact mini excavator is its optimized body structure for narrow spaces. The true zero-tail swing design ensures the machine’s tail never exceeds the track width during 360° full rotation, completely avoiding collisions with walls, buildings, fences, and trees. This solves the core pain point of traditional mini excavators that cannot work close to building edges, making it the best choice for backyard remodeling, wall-side trenching, and indoor demolition.

Equipped with an independent side swing boom, the RT30 can adjust the boom’s lateral working range freely without frequent machine repositioning, eliminating working dead corners completely. The ultra-compact body size (4200mm*1550mm*2480mm) is easy to transport via small trailers and pickup trucks, saving transportation time and costs. Meanwhile, the low 27.3kPa ground pressure rubber tracks prevent damage to lawns, pavements, and farmland ground, which is irreplaceable for high-precision landscaping projects.

Intelligent Operation & Upgraded Comfortable Working Experience

Abandoning the traditional mechanical instrument panel, the RT30 mini crawler excavator is equipped with a 7-inch HD intelligent touch screen cockpit, supporting dual metric and imperial unit switching. The screen centrally displays real-time engine data, hydraulic system parameters, working hours, and automatic fault diagnosis information, helping operators quickly judge machine status and reduce maintenance failures. It also supports personalized setting of attachment parameters, realizing intelligent and refined operation.

To adapt to different working environments and user needs, we provide two cab configurations. The lightweight safety canopy is cost-effective and suitable for open-air simple operations; the upgraded enclosed luxury cabin with A/C has a panoramic wide-view window design and ergonomic shock-absorbing seats, providing a comfortable working environment in high-temperature summer and cold winter, effectively reducing operator fatigue during long-hour work. The reasonably arranged proportional control levers are simple to operate, and novice workers can get started quickly with zero threshold.

Full Attachment Compatibility & Multi-Scenario Application

The DERETTE RT30 3 ton mini excavator is built with standard primary auxiliary hydraulic circuits and optional secondary auxiliary circuits, supporting the full range of hydraulic attachments on the market. One machine can realize multiple functions, greatly reducing equipment procurement costs for users. Compatible attachments include hydraulic quick hitch, mechanical quick coupler, hydraulic breaker hammer, auger drill, thumb clamp, wide grading bucket, and narrow trenching bucket.

It covers almost all light engineering operation scenarios and is widely applicable:

• Commercial & Residential Landscaping: Soil leveling, tree pit digging, fence post drilling, lawn renovation, garden terrain transformation

• Municipal Small Engineering: Sidewalk repair, drainage pipeline trenching, green belt construction, urban small-scale demolition

• Farm & Orchard Maintenance: Irrigation ditch excavation, barn renovation, farmland cleaning, fertilizer pit digging

• Confined Space Renovation: Backyard reconstruction, basement debris cleaning, narrow alley construction

• Light Forestry Construction: Road repair, brush cleaning, stump removal, forest fire barrier digging

Rigorous Craftsmanship & Long-Lasting Durability

Focusing on the durability of construction machinery, the RT30 mini excavator adopts high-strength cast steel swing brackets and integrated thickened steel body panels. The internal hidden hose routing design avoids pipeline wear and tear caused by external friction and collision, effectively extending the service life of hydraulic pipelines and reducing later maintenance costs. The whole machine undergoes strict factory testing and quality inspection, adapting to high-frequency working conditions of equipment rental companies and long-term outdoor harsh environment operation.
