200-300 hp Dozer
The 200-300 hp dozer class represents the D7/D8 segment: heavy-production machines built for land clearing, substantial cut-and-push work, and full-scale earthmoving operations. With operating weights from 17,400 to 40,000 kg and engines delivering 160 to 287 hp, these dozers handle the bulk of large-site grading, dam construction, and major infrastructure projects. This size sits between the 130-200 hp machines used for mid-range grading and the 300+ hp ultra-heavy dozers reserved for mining and quarry work.

Spécifications clés
| Spécification | Plage typique | Signification |
|---|---|---|
| Engine power | 160-287 hp | Sufficient power for heavy cutting, ripping hardpan, and pushing loaded scrapers across long hauls. |
| Operating weight | 38,360–88,185 lb (17,400–40,000 kg) | Mass provides drawbar pull and traction for deep cuts and sustained pushing in difficult ground. |
| Blade capacity | 3-6 m³ (typical) | Large blade volumes move significant material per pass, accelerating mass excavation and land clearing. |
Comment choisir
The 200-300 hp class is appropriate for large-scale earthmoving where production targets demand heavy cutting power and high blade capacity: highway construction, reservoir excavation, and mine-site development. When grading operations involve lighter cuts, finish work, or moderately sized sites, the 130-200 hp Dozer class offers adequate power with lower operating costs and easier transport. For ultra-deep cuts, large-scale mining overburden removal, or quarry benching, the 300+ hp Dozer class provides the drawbar pull and mass required for those extreme conditions.
Ce que cette taille peut gérer
- Highway corridor mass grading with 1-2 m cuts over kilometers of alignment
- Reservoir and dam foundation excavation requiring sustained heavy pushing
- Large residential subdivision rough grading and land clearing of timber and stumps
- Airport runway subgrade preparation and heavy compaction support
- Pipeline right-of-way clearing and trench spoil management across cross-country routes
- Quarry access road construction and bench development in fractured rock
Sécurité et opération
- ROPS/FOPS-certified cabs standard; operator must maintain visibility around the blade and rear counterweight during maneuvers
- Ground-bearing pressure and operating weight require assessment of subsurface conditions to prevent slope failure or undermining
- Blade and ripper hydraulics operate under high pressure; lockout/tagout procedures mandatory during service and attachment changes
- Spotter or signalperson recommended when working near utilities, structures, or other equipment due to limited rear visibility
Transport et logistique
- Heavy lowboy or multi-axle hydraulic trailer required; machines in this class exceed legal road limits without permits
- Combined transport weight typically 25,000-50,000 kg, requiring Class 8 tractor and escort depending on jurisdiction
- Track removal or transport-configuration procedures common for machines approaching 40,000 kg to meet axle-weight regulations
Alimentation
- Diesel fuel consumption 20-40 liters per hour under load; bulk on-site fuel storage or scheduled tanker deliveries typical for extended operations
- Diesel exhaust fluid (DEF) required for Tier 4 Final / Stage V emissions compliance on newer models
- Cold-weather operations may require block heaters or auxiliary pre-heat systems for reliable starting below -10°C
