Mitchell Trim is owned by Stewart Mitchell who has over 30 years experience in the construction industry.
Out of 30 years in the industry, Stewart has worked as a surveyor, foreman and leading hand with 18 years as a full time grader operator.
Mitchell Trim was started in 2009 and Mitchell Trim has been proud to work on a variety of road projects for different construction companies throughout QLD and NSW.
Mitchell Trim owns the latest 150 AWD has six wheel drive capabilities with a larger C9 engine. The grader can be operated like a conventional rear wheel drive grader. When six wheel drive is activated the machine has pull power as well as push power, increasing work capabilities. The C9 engine comfortably handles the machine with good fuel economy. The 150 AWD is an efficient choice for earthworks and pavements.
The GPS can be tuned into any base station (Trimble, Topcon and Leica). It is quick to set up and gives flexibility for the machine to move around the project as long as the sky is visible from the mast. GPS is generally used for bulk earthworks – GPS accuracy can be as good as +/- 10mm
The grader is fitted with a Trimble Earthworks control system. The Trimble Earthworks used with the Universal Total Station is a full 3D control system that puts the site plan – design surfaces, grades and alignments – inside the cab.
The on-board computer uses position information, and compares it to the design elevation to compute cut or fill to grade. This information displays on the Trimble Earthworks screen- in plan, profile, cross-section view, or text. The cut/fill data is also used to drive the valves for automatic blade control.
Mitchell Trim owns the latest 930 Trimble Universal Total Station, with a T7 controller which offers the complete 3D machine control solution.
The total station has a radio link to the machine control mounted to the grader blade. It uses active target technology to lock onto and track the target. The high up-date rate, low latency and synchronized angles and distance measurements capabilities make it perfect for dynamic applications. Once the bulk earthworks is completed, the UTS is the best solution as accuracy is much better than GPS at +/- 2mm.
