Motor Grader

A 130 HP motor grader is a road maintenance machine. Its normal work is reshaping gravel roads, cutting and pulling drains, restoring camber and maintaining haul roads, rather than bulk cutting. The specification that matters on a grader is the moldboard and the control system: blade length and thickness against the material, and how precisely the blade can be held to grade over a long pass. A scarifier or rear ripper decides whether the machine can break a compacted surface before reshaping it, which on old gravel roads is most of the job. We build to the buyer's requirement, including against a tender's own technical annexure.

This entry covers the motor grader across a 130 to 220 HP range rather than at one fixed power. The right power class follows from the work: maintenance grading of existing gravel roads sits at the lower end, new road formation in the middle, and continuous mine haul road duty at the top. Because the range is wide, the specification conversation starts with the application rather than with the machine. Tell us the surface, the tolerance and the hours the machine is expected to work, and the power class, moldboard and wear package follow from that. We manufacture to the buyer's own schedule, including a tender's technical annexure.

At 170 HP the motor grader moves from maintenance into formation work: cutting subgrade, trimming base course to tolerance and forming road profile on new construction rather than restoring an existing one. Formation work is measured against a tolerance, so the questions at order are about accuracy and reach as much as power. Moldboard length, circle drive, articulation and whether the machine carries grade control determine whether it can hold the tolerance a contract specifies over a long pass. Manufacture is to the buyer's own schedule, and a tender annexure is quoted and built against in full.

A 180 HP motor grader is specified for heavy formation and for mine haul road maintenance, where the machine works continuously in coarse material and the blade is loaded hard for long passes. Duty of that kind is hard on the circle and the moldboard rather than on the engine, so the wear specification is where the machine is won or lost: circle wear inserts, blade thickness, and cutting edge material all decide what the grader costs to keep working over a year. Build is to the buyer's requirement, including against a tender technical annexure where one is issued.

220HP motor graders — a motor grader at 220 horsepower for road formation, grading, levelling, ditch cutting and haul road maintenance.

A grader's real work is fine blade control, and the operator does more for the finished surface than the horsepower does. The power rating matters for ripping and for working in hard material; blade width, moldboard control and the availability of a ripper or scarifier matter for everything else. At 220 HP this suits road construction and mine haul road maintenance rather than light levelling. Contact us with your application and whether you need a ripper fitted for a specification.
