Both large and small construction and earthmoving projects will often require a grader. For civil engineering projects, graders are used to precisely refine the level of a surface that a bulldozer or scraper has “rough graded”.
We have a number of Sydney grader hire suppliers on the iSeekplant database, and we’ve broken down everything you need to know about hiring a grader in Australia.
Graders have a range of attachments, meaning they can be set to different jobs, and with a long blade and three axles on the front, they’re perfect for the creation of an even and flat preparation surface or final product.
Graders were traditionally used to maintain roads and flatten surfaces before asphalt was applied. These days, graders are often used for spreading, fine grading and earthmoving, clearing brush and debris, and even snow removal.
Graders can produce both horizontal and inclined surfaces, and depending on the depth, can also be used for the digging of drainage ditches.
Caterpillar is responsible for almost half of the annual motor grader sales around the world. Its first grader was introduced to the market in 1926, and the company produced many models in the years following, with the M Series machines (joystick-controlled) released in 2006.
Grader hire suppliers in Newcastle categorise their graders by blade width, from less than 10ft, to 12ft, 14ft, 16ft, and right up to 24ft. Some of the most well-known and respected grader manufacturers include Terex, Komatsu, John Deere and Caterpillar, however there are so many grader hire suppliers in Melbourne that you’ll be sure to find the perfect fit for your specific needs.
Graders have a movable blade, and different sized blades are required for different jobs. The blades are mounted onto the grader, attached under the frame with a ring that swivels vertically, adjusting the angle of the blade. This means that the grader can work sideways on jobs like sloping banks and pulling ditches.
A Scarifier blade penetrates gravel, frozen and hard-packed surface with less horsepower and down pressure than standard blades, and will also usually do it with fewer passes. The blades feature individual self-sharpening and rotating tools so blades last longer and allow an even cutting height.
A dual-carbide planer blade has two inserts in the edge, made of carbide. These blades are ideal for low-impact, highly-abrasive jobs.
Perth grader hire suppliers are likely to let you know that the thickness of the edge of the blade is an important consideration, and a thicker edge will be less susceptible to breakage and will also wear for longer, however the penetration is less compared to a thinner edge. A thicker edge also requires more down pressure to cut and penetrate material which can burn more fuel.
Using an edge that’s too thin or small can also make it more susceptible to early wear and damage, and there are many different materials used that can influence how long a blade will last for.
Certain types of graders are used and we categorise them by their width of blade – from below 10ft, through to 12ft, 14ft, 16ft and larger. The largest grader we have on our site is a Caterpillar 24M.
