CAT CLASS: HQ-10198

70,000-100,000 lb Track Excavator

The 70,000-100,000 lb track excavator class spans 35 to 45 tons operating weight and defines the production threshold for highway construction and mass grading operations. These machines transition from loading highway dump trucks to serving off-road haul trucks on large earthmoving sites. With engine power from 172 to 344 hp and reach extending beyond 33 feet, this size class supports continuous, high-volume excavation and material handling.

Spécifications clés

Spécification	Plage typique	Signification
Operating weight	31,900–45,000 kg (70,400–99,200 lb)	Defines the 35-45 ton class; provides stability for large bucket forces and heavy production cycles.
Engine power	172–344 hp	Powers hydraulic systems for continuous digging in dense material and fast cycle times under load.
Max dig depth	19–25 ft (5.8–7.6 m)	Accommodates deep utility trenches, retention ponds, and multi-lift excavation below grade.
Max reach	33.0+ ft	Enables loading into off-road truck beds and working across wide cuts without repositioning.

Comment choisir

This size class is suited to highway construction, large commercial site development, and mass grading where production rate and the ability to load articulated dump trucks or off-road haul units matter more than mobility. When the project involves primarily highway dump trucks, smaller site footprints, or frequent relocation, the 50,000-70,000 lb Track Excavator offers easier transport and lower operating cost. For mine-scale earthmoving, quarry loading, or projects demanding bucket capacity above 3 cubic yards, the 100,000+ lb Track Excavator delivers the required production and reach.

Ce que cette taille peut gérer

Highway widening and interstate reconstruction with multi-lane excavation
Mass grading for industrial parks and distribution centers spanning dozens of acres
Loading 30- to 40-ton articulated dump trucks in continuous earthmoving operations
Deep sewer and stormwater trunk line installation requiring 20+ foot dig depth
Retention basin and detention pond excavation with large-volume cuts
Demolition of heavy commercial structures with high-reach attachments

Sécurité et opération

Operators must maintain awareness of overhead utilities and clearance; boom height can exceed 25 feet at full extension
Spotter or grade personnel required when loading haul trucks due to limited rear and side visibility from cab
Ground conditions must support 10+ psi bearing pressure per track; slope stability critical when working near excavation edges
Two-way communication systems standard on projects with multiple machines and haul units operating in close proximity

Transport et logistique

Requires heavyweight lowboy or RGN trailer rated for 50+ ton combined load; most units exceed legal width without permits
Transport typically arranged by specialized heavy-haul carriers due to weight, width, and permit coordination
Loading and unloading demand reinforced ramps or dock-height access; ground-level drive-off sites must support concentrated axle loads

Alimentation

Diesel fuel consumption ranges from 8 to 15 gallons per hour under continuous production; bulk fuel delivery typical on multi-week projects
DEF (diesel exhaust fluid) required for Tier 4 Final emissions systems; consumption approximately 2-3% of diesel volume
Hydraulic oil reservoirs hold 90 to 150 gallons; filtration and cooling systems sized for sustained high-flow operation

Questions fréquentes

What bucket size does this class typically use?

Bucket capacity generally ranges from 2.0 to 3.5 cubic yards, selected based on material density and target truck payload. Heavier materials or precise load targeting favor smaller buckets; high-volume, lighter soils support larger capacities.

How does this size compare to the next class down for highway work?

The 50,000-70,000 lb class handles most highway projects that rely on highway dump trucks, while the 70,000-100,000 lb class becomes advantageous when off-road haul units, deep utility runs, or maximum daily yardage drive the schedule.

What site access does this weight class require?

Haul routes must accommodate 11- to 12-foot widths and lowboy trailer turn radii; on-site ground must support concentrated loads during unloading and operation, often requiring geotextile or temporary matting in soft conditions.
