50,000-70,000 lb Track Excavator
The 50,000-70,000 lb track excavator represents the 25-30 ton class, positioned between mid-size excavators and true large excavation machines. These machines deliver the reach and breakout force required for deep basements, trunk sewer installation, and heavy demolition with hydraulic shears or processors. With engines ranging from 117 to 282 hp and dig depths to 23.6 ft, this class bridges general earthwork and specialized heavy-duty applications.

Especificaciones clave
| Especificación | Rango típico | Qué significa |
|---|---|---|
| Operating weight | 50,000–70,000 lb (22,680–31,750 kg) | Defines the 25-30 ton class, balancing stability for heavy demolition attachments with transport practicality. |
| Engine power | 117–282 hp | Powers hydraulic circuits for high-flow attachments like shears, processors, and large buckets. |
| Max dig depth | 20–23.6 ft (6.1–7.2 m) | Reaches deep foundation excavation and trunk sewer grades without extensive ramping. |
| Max reach | 31–35 ft (9.4–10.7 m) | Provides working envelope for wide trenches, building demolition, and slope work from a stable platform. |
Cómo elegir
The 50,000-70,000 lb class is appropriate for deep excavation beyond 20 ft, trunk utility installation, and demolition requiring shear or processor attachments that demand high auxiliary hydraulic flow. When site work involves standard utility trenching, roadwork, or building excavation under 18 ft, the 33,000-50,000 lb Track Excavator offers easier transport and lower operating cost. For quarry work, large-scale mass excavation, or demolition of multi-story structures where bucket capacity and breakout force are limiting factors, the 70,000-100,000 lb Track Excavator becomes necessary.
Lo que maneja este tamaño
- Deep basement excavation for commercial buildings with 20+ ft dig depth
- Trunk sewer and storm drain installation in 15-20 ft trenches
- Building demolition with hydraulic shear or concrete processor attachments
- Large retention pond and detention basin excavation
- Bridge abutment and pier foundation excavation
- Heavy rock breaking with hydraulic hammer on stable platform
Seguridad y operación
- ROPS/FOPS cab standard; falling object protection critical during demolition and shear work
- Ground bearing pressure 7-10 psi; matting or reinforcement necessary on soft soils and finished grades
- Swing radius 15-18 ft; barricades and spotters required in congested sites or near structures
- Attachment quick-coupler lockout verification mandatory; hydraulic thumb and shear pin-on inspection before each shift
Transporte y logística
- Requires lowboy or RGN trailer rated for 30+ ton loads; detachable counterweight common for transport weight reduction
- Over-width permits typically required; total transport width 10-12 ft with tracks, may require removal of rails or handrails
- Loading requires 15+ ton capacity ramps or dock; self-loading via walk ramps feasible on suitable lowboys
Alimentación
- Diesel fuel consumption 8-15 gallons per hour under load; 150-200 gallon fuel tank typical for full-day operation
- Tier 4 Final emissions systems standard on current models; diesel exhaust fluid (DEF) required on most engines
- Auxiliary hydraulic circuits deliver 30-60 gpm for high-flow attachments like processors and multi-jaw grapples
