RUNTX 21 Ton Crawler Excavator
Product Feature
What Is a 21 Ton Crawler Excavator?
A 21 ton crawler excavator is a medium-duty hydraulic excavator commonly used for earthmoving, trenching, foundation excavation, site preparation and infrastructure construction. Its tracked undercarriage provides a stable working platform and reliable traction when operating on loose soil, uneven ground and construction sites.
Compared with smaller excavators, machines in this weight class provide greater digging capacity and working reach while remaining practical for a wide range of general construction projects. They are commonly selected by contractors, equipment rental companies and infrastructure operators that require a balance between digging performance, transport size and job-site versatility.
The RUNTX RTX210 21 Ton Crawler Excavator has an operating weight of 21.5 tons and a standard bucket capacity of 0.9 m³. Powered by an ISUZU 6BG1 engine rated at 120 kW, it provides a maximum excavation depth of 6252 mm and a maximum excavation reach of 9820 mm for construction and earthmoving applications.
RUNTX RTX210 Key Features
1. ISUZU 6BG1 Engine
The RTX210 is equipped with an ISUZU 6BG1 engine delivering a rated output of 120 kW at 2150 r/min. The engine provides the power required for digging, lifting and travel functions across general construction and earthmoving applications.
2. Hydraulic System for Excavation Work
With a working hydraulic pressure of 34.3 MPa and a dual-pump hydraulic configuration, the RTX210 is designed to support digging, boom, arm and swing operations during normal excavation cycles.
3. Practical Digging Range
The excavator offers a maximum digging depth of 6252 mm, maximum digging reach of 9820 mm and maximum excavation height of 9270 mm. This working range makes the machine suitable for trench excavation, foundation work and general earthmoving.
4. 0.9 m³ Bucket Capacity
A standard bucket capacity of 0.9 m³ provides a practical balance between excavation volume and machine size for common soil excavation, loading and site preparation operations.
5. Crawler Undercarriage and Traction
The tracked undercarriage provides stable ground contact for operation on construction sites and uneven surfaces. A traction force of 220 kN, 600 mm track shoes and 470 mm minimum ground clearance support machine movement across typical job-site conditions.
6. Dual Travel Speed
High and low travel speeds of 5.8 km/h and 3.2 km/h allow the operator to select an appropriate travel mode when repositioning the excavator or working within the job site.
Applications
1. Construction and Earthmoving
Suitable for site preparation, bulk excavation, ground leveling and movement of soil and construction materials.
2. Foundation and Trenching Work
The 6252 mm maximum digging depth supports foundation excavation, drainage work, utility trenches and other below-ground construction tasks.
3. Road and Infrastructure Construction
Suitable for road preparation, drainage construction, municipal projects and general infrastructure earthworks.
4. Material Loading and Handling
The RTX210 can be used for loading excavated soil and other suitable materials into trucks or repositioning materials around construction sites.
5. Agricultural and Land Development
Suitable for land preparation, drainage excavation, pond construction and other medium-scale agricultural or land development projects.
