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.

Spécifications clés

Spécification	Plage typique	Signification
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.

Comment choisir

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.

Ce que cette taille peut gérer

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

Sécurité et opération

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 et logistique

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

Alimentation

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

Questions fréquentes

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.
