CAT CLASS: HQ-10197
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.

Key specifications
| Specification | Typical range | What it means |
|---|---|---|
| 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. |
How to choose
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.
What this size handles
- 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
Safety & operation
- 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
Transport & logistics
- 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
Power & supply
- 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
Frequently asked
What distinguishes the 50,000-70,000 lb class from the 33,000-50,000 lb class?
The 50,000-70,000 lb class provides 3-5 ft greater dig depth (20-23.6 ft vs. 16-19 ft), higher auxiliary hydraulic flow for demolition attachments, and the stability to operate heavy shears and processors without counterweight concerns. The smaller class suffices for utility work and general excavation under 18 ft.
Can this class operate a concrete pulverizer or scrap shear?
Yes, the 117-282 hp engines and high-flow hydraulic circuits in this class are sized for processors, shears, and pulverizers in the 6,000-10,000 lb range. Auxiliary flow rates of 30-60 gpm support continuous operation of these attachments on multi-story building demolition.
What trailer class is required for transport?
A lowboy or removable gooseneck (RGN) trailer rated for 35+ tons is typical, as combined machine and trailer weight often exceeds 80,000 lb gross. Many operators remove counterweights or use detachable configurations to stay within regional transport limits.
