RUNTX 78 Ton Crawler Excavator
Product Feature
What Is a 78 Ton Crawler Excavator?
A 78 ton crawler excavator is a heavy-duty hydraulic excavator designed for large-scale earthmoving, mining support, quarry work and infrastructure excavation. Its tracked undercarriage provides a stable operating platform for demanding jobs that require high digging capability, large bucket capacity and strong traction.
Excavators in this class are commonly selected for high-volume excavation and material loading where production efficiency is important. Compared with medium-size excavators, they provide greater operating weight, larger bucket capacity and stronger undercarriage support for heavy-duty applications.
The RUNTX RTX8050 78 Ton Crawler Excavator has an operating weight of 77.2 tons and a 4.0 m³ bucket. Powered by a Cummins QSX15 engine rated at 336 kW at 2100 r/min, it provides a maximum digging depth of 6868 mm and a maximum excavation reach at ground level of 12064 mm.
RUNTX RTX8050 Key Features
1. 336 kW Cummins QSX15 Engine
The RTX8050 is equipped with a Cummins QSX15 engine rated at 336 kW at 2100 r/min. This engine output supports heavy excavation, hydraulic operation, swing functions and travel on demanding work sites.
2. 4.0 m³ Bucket Capacity
The 4.0 m³ bucket provides large material handling capacity for bulk soil excavation, loading and earthmoving operations. This configuration is suitable for projects that require higher material volume per cycle.
3. High-Flow Hydraulic System
The hydraulic system provides a maximum flow of 490 × 2 L/min, with listed working pressure values of 31.4 MPa and 34.3 MPa. The K3V280DH hydraulic pump supports coordinated boom, arm, bucket, swing and travel operations during heavy excavation cycles.
4. Strong Arm Digging and Traction Performance
The RTX8050 provides an arm digging force of 300 / 328 kN and a traction force of 553 kN. These specifications support heavy excavation, breakout performance and machine movement on demanding project sites.
5. Extended Working Range
The machine provides a maximum excavation height of 11762 mm, a maximum digging depth of 6868 mm and a maximum excavation reach at ground level of 12064 mm. This operating range supports large excavation and material handling applications.
6. Heavy-Duty Undercarriage
The RTX8050 uses 650 mm track shoes, a 4720 mm track grounding length and adjustable width values listed as 2750 / 3350 mm track gauge and 3400 / 4000 mm overall track width. This undercarriage layout provides a broad and stable operating base for heavy-duty applications.
7. 553 kN Traction Force
A traction force of 553 kN supports machine movement and positioning on suitable heavy job sites. High and low travel speeds of 4.8 km/h and 3.0 km/h provide two travel modes for repositioning the excavator.
Applications
1. Large-Scale Earthmoving
Suitable for bulk excavation, large site preparation, soil removal and high-volume earthmoving projects.
2. Mining Operations
The 4.0 m³ bucket, high hydraulic flow and strong traction make the RTX8050 suitable for supporting excavation, loading and site preparation in mining applications.
3. Quarry Work
The excavator can support suitable digging, loading and material handling tasks in quarry projects where a heavy crawler excavator is required.
4. Infrastructure Excavation
The RTX8050 can be used for large foundation excavation, road projects, bridge-related earthworks and other heavy infrastructure construction tasks.
5. Bulk Material Loading
The 4.0 m³ bucket supports loading of excavated soil and compatible loose materials into trucks on large construction and mining sites.
