Motor Grader

motor grader

Motor graders are widely used to loosen the top surface of the road to create a flat surface in road construction. Graders can come with multiple attachments such as; a ripper, front blade or mid scarifier. CAT 140H is a common grader which is usually built in the USA or Brazil and is used by most road contractors. The CAT 140K looks very similar but is built in China. M-series graders are controlled with joysticks, not levers and a steering wheel. This reduces operator fatigue over a work shift. Mining applications use the larger 16 series, 160H, 160M, 16M as these are bigger. Other common graders are Komatsu, Volvo and John Deere.
