CAT CLASS: HQ-10196

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.

Spécifications clés

Spécification	Plage typique	Signification
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.

Comment choisir

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.

Ce que cette taille peut gérer

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

Sécurité et opération

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

Transport et logistique

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

Alimentation

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

Questions fréquentes

What bucket size pairs with machines in this weight class?

Typical general-purpose buckets range from 1.5 to 2.5 yd³. Bucket selection depends on material density, truck capacity, and whether the machine will prioritize digging force or cycle speed.

Can this size class operate a hydraulic compactor or large grapple?

Yes. Hydraulic flow and lift capacity in this class support compaction wheels, multi-processor attachments, and sorting grapples commonly used in demolition and waste handling. Verify machine auxiliary flow matches attachment requirements.

What differentiates a 40,000 lb machine from a 48,000 lb machine within this band?

The heavier end of the range typically offers longer reach, greater dig depth, higher auxiliary hydraulic flow, and larger standard bucket capacity. Both fall within the same trailer and permit category, so the choice hinges on job-specific reach and production demands.
