CAT CLASS: HQ-10229

200+ hp Motor Grader

The 200+ hp motor grader class comprises heavy-duty machines engineered for mine haul road maintenance, large-scale earthworks, and industrial site preparation. These graders deliver engine power from 158 to 755 horsepower and operating weights spanning 14,550 to 74,000 kg, with blade widths and moldboard capacities scaled to move substantial volumes of material in challenging conditions. This size class sits at the top of the motor grader ladder, above the 150–200 hp band, and represents the largest machines in contractor and industry fleets.

Spécifications clés

Spécification	Plage typique	Signification
Engine power	158–755 hp	Power range supports applications from large civil earthworks through heavy mining haul road grading.
Operating weight	32,077–163,142 lb (14,550–74,000 kg)	Mass provides blade penetration and traction in hard, uncompacted, or rocky material.
Blade width	3.7–7.3 m typical	Wide moldboards cover haul roads and building pads in fewer passes.
Drawbar pull	High torque at low speed	Enables scarifier ripper engagement and grading through dense aggregate or subgrade.

Comment choisir

The 200+ hp motor grader is appropriate for mine haul road maintenance, large dam and levee construction, airport runway grading, and industrial site earthworks where blade width, mass, and drawbar pull are needed to cut, spread, and finish in fewer passes. Operators working on large-scale projects with hard or rocky subgrades, or maintaining multi-lane haul roads, will find the power and weight of this class necessary. For highway construction, municipal road work, or subdivision grading where machine size and fuel consumption are concerns, the 150–200 hp Motor Grader offers sufficient capacity with lower operating cost and easier transport. Projects requiring the largest available blade widths and maximum traction in mining or heavy industrial environments specify this top class.

Ce que cette taille peut gérer

Grading and maintaining haul roads at open-pit mines
Final grade and drainage on airport runways and taxiways
Large dam embankment shaping and compaction preparation
Industrial park and logistics center site preparation
Highway interchange earthworks and subgrade finishing
Levee construction and flood-control earthworks

Sécurité et opération

ROPS/FOPS certified cabs standard; operators work at elevation with limited visibility to the rear and blade ends
Blade articulation, scarifier, and ripper controls require coordination training to prevent tip-over or equipment contact
Wide turning radius and long wheelbase demand adequate operating clearance from walls, slopes, and other equipment
High fuel capacity and pressurized hydraulic systems require spill containment and fire-suppression awareness on site

Transport et logistique

Heavy-duty lowboy or multi-axle tilt trailers required; machines in this weight class often exceed legal road limits without permits
Transport width with blade attached may require dismounting or special-width permits depending on jurisdiction
Self-loading onto low-angle tilt trailers common; smaller models in the range may use standard heavy equipment trailers

Alimentation

Diesel fuel; daily consumption varies widely with engine size, load factor, and duty cycle but can exceed 200–400 liters per shift on large models
On-site bulk fuel storage typical for multi-machine mine or large civil projects; DEF (diesel exhaust fluid) required for Tier 4 Final engines
Cold-weather operations may require block heaters or auxiliary warming systems for reliable starting

Questions fréquentes

What differentiates a 200+ hp grader from smaller classes in mine applications?

The additional power, weight, and blade width enable fewer passes on wide haul roads, better penetration in compacted or rocky material, and the drawbar pull needed to operate heavy scarifiers without loss of traction.

Are machines at the upper end of this range (600+ hp) common in the fleet?

Ultra-heavy graders above 500 hp are less common in general inventory and more often owned by large mining contractors or specialized earthwork firms; mid-range models (200–350 hp) see broader availability.

What transport logistics should be planned for a 200+ hp motor grader?

Machines in this class typically require permitted heavy-haul transport, advance route planning for overhead clearances and bridge ratings, and coordination with utility companies where blade width exceeds standard lane dimensions.
