The RT15 is a top-tier mini excavator engineered to maximize your productivity through advanced hydraulic mastery. By inte-grating a sophisticated Variable Piston Pump and a Load-Sensing Valve system, the RT15 delivers silky-smooth simultaneous movements and exceptional operator comfort. Whether for landscaping, trenching, or urban construction, this compact powerhouse intelligently optimizes flow and pressure to cut fuel costs while boosting breakout force—ensuring the fastest cycle times and the highest return on your investment.
The Derette RT15 is a precision-built 1.5 ton compact crawler excavator engineered for versatile light-to-medium digging operations. Designed and assembled with heavy-duty core components, this mini digger balances compact body size and reliable working performance. Buyers get two genuine engine options: Kubota D902 or Yanmar 374F, to satisfy different regional emission standards. Fitted with variable piston pump hydraulic system, retractable undercarriage and boom side swing function, RT15 is a solid, low-maintenance machine built for long service life. It is widely adopted by landscaping contractors, utility installers and equipment rental companies worldwide.
Product Advantages
1. Boom Side Swing for Wall-Adjacent Digging
The swingable boom structure enables the bucket to work parallel to building walls and foundations. Operators can finish trenching and excavation work close to structures without repeatedly repositioning the whole machine, greatly improving working efficiency in confined sites.
2. Ergonomic Operator Station
The RT15 features a well-designed operating space with adjustable seat and intuitive pilot controls. The control layout follows human engineering principles to reduce operator fatigue during long working shifts. Clear instrument panel keeps all machine status visible at a glance.
3. Hydraulic Retractable Undercarriage
The crawler tracks are hydraulically adjustable. Narrow down to 1020 mm to pass through 1.1-meter narrow gates, alleys and yard entrances. Expand the track width to 1270 mm when digging, offering enhanced stability and anti-tipping performance on uneven ground.
4. Protected Dual Speed Travel Motor
Equipped with hidden 2-speed travel motors delivering 2.2 km/h and 4.3 km/h travel speed. The enclosed design shields motors from rocks, mud and debris on rough job sites, reducing wear and tear and cutting maintenance frequency.
5. Standard Quick Coupler for Multi-Tool Use
Comes factory-equipped with quick attachment coupler. Operators can rapidly swap buckets, hydraulic breakers, augers and grapples. One RT15 machine can handle excavation, breaking, drilling and material grabbing tasks, maximizing your equipment investment.
