33,000-50,000 lb Track Excavator
The 33,000–50,000 lb track excavator represents the 20-ton class, the industry's primary mass-excavation workhorse. This size class loads a tandem axle dump truck in four bucket passes and swings breakers up to 1,000 lb for heavy demolition and rock breaking. Positioned between the 22,000–33,000 lb Track Excavator and the 50,000–70,000 lb Track Excavator, this band balances production capacity with site mobility.

Especificaciones clave
| Especificación | Rango típico | Qué significa |
|---|---|---|
| Operating weight | 33,000–50,000 lb (15–23 metric tons) | Defines the size class and determines trailer requirements and ground bearing pressure. |
| Engine power | 74–231 hp | Drives hydraulic flow for digging force, swing torque, and attachment operation. |
| Max dig depth | 21–25 ft (6.4–7.6 m) | Reaches deep utility trenches, basements, and large-diameter pipe installations. |
| Max reach | 30–35 ft (9.1–10.7 m) | Enables work across roadways, large footings, and retention pond slopes from one setup. |
Cómo elegir
This size class is appropriate for high-volume earthmoving, loading articulated and tandem dump trucks efficiently, deep utility installations, and commercial foundation excavation. The larger bucket capacity and digging force outpace the 22,000–33,000 lb Track Excavator on projects requiring sustained production and deep reach. When work involves residential lots, tight urban sites, or trailer weight restrictions under 40,000 lb combined, the 22,000–33,000 lb Track Excavator offers better maneuverability and transport economy. For quarry stripping, large-scale grading, or projects requiring buckets above 2.5 yd³, the 50,000–70,000 lb Track Excavator delivers the necessary breakout force and cycle speed.
Lo que maneja este tamaño
- Excavating commercial building foundations 12–20 ft deep
- Loading tandem dump trucks on highway widening and grading projects
- Installing large-diameter storm and sanitary sewer mains in 18–24 ft trenches
- Mass excavation for retention ponds and detention basins
- Operating hydraulic hammers up to 1,000 lb for rock trenching and demolition
- Digging and shaping slopes on dam and levee construction
Seguridad y operación
- Operators must maintain awareness of swing radius; tail swing and counterweight extend well beyond track width
- Ground bearing pressure and slope stability become critical on soft soils; mats or geotextile reinforcement may be necessary
- Hydraulic hammer operation generates significant vibration and noise; hearing protection and isolation mounts are standard practice
- Spoil pile placement and truck spotting require clear communication protocols to prevent struck-by incidents in high-production environments
Transporte y logística
- Requires lowboy or tilt-deck trailer rated 45,000–60,000 lb; combined GVW typically exceeds simple CDL limits
- Tractor and loaded trailer combination often requires CDL Class A with appropriate endorsements depending on jurisdiction
- Track width and machine height may necessitate overwidth permits; verify state and local transport regulations before moving
Alimentación
- Diesel fuel consumption typically 4–8 gallons per hour under normal digging and loading cycles
- Onboard fuel tanks generally hold 80–120 gallons, supporting 10–20 hours of operation between refueling
- DEF (diesel exhaust fluid) systems on Tier 4 Final engines require periodic topping alongside fuel service
