![]() Both methods allow you to achieve a precise height and angle, while using an exact amount of materials and manpower to complete the job. Automatic systems for both 2-D and 3-D even adjust the blade for the operator. A 3-D system is best for complex contours. The control box’s computer compares the cutting-edge position to the design elevations and then displays cut-and-fill information. A receiver on the machine reads the GPS signals received by an elevated antenna, as well as correctional data transmitted by a jobsite-based station to calculate an accurate, cutting-edge position. 3-D systems-With a 3-D grade control system, the job’s design elevations are input into the crawler dozer’s or motor grader’s control box.Often, these systems come with a control box that includes software with a powerful range of features specifically designed for lift and/or tilt control on dozers and motor graders. The 2-D grade control system is ideal for applications with tight tolerances and finished grade work. With the laser receivers, operators can use the system for fine grading plane surfaces. Using a motor grader or crawler dozer, the system allows stringline, previous pass or curb and gutter tracing. The 2-D system uses angle sensors and rotational sensors to calculate the cross slope of either side of the blade, as well as a laser receiver to provide elevation control. Entry-level 2-D systems-The 2-D grade control system allows operators to set up a laser transmitter to cut to their desired grade, on both flat and sloping surfaces.There are many grade control systems available in the market today: Grade control drastically eliminates the need for grade stakes and additional workers on the jobsite, even during the verification process. With the system ready to go, the contractor’s accuracy is improved, reducing the number of passes for successful job completion. Next, the contractor creates a 3-D model from the digital design, and then he/she will localize it and integrate the model into the on-site data collector and grade control machine. After completing his/her own accurate estimate, the contractor can create a competitive bid and win the contract. This process is known as takeoff, which is comparing the plan quantity versus takeoff quantity using construction software. Using a grade management system, contractors can topo the site themselves to verify the engineer’s quantities on the initial, 3-D contoured map of the existing site. Once the design is in place, contractors are brought in to prepare an estimate. From this map, a design of the shopping center is then created. First, the developer will hire an engineer to build a 2-D representation of a 3-D land surface, or a topo. For example, a developer plans to build a shopping center with a huge parking lot, a commons and a pond on a stretch of land. With grade control, the impact on an operation’s return on investment is almost immediate. A grade control system gives contractors the accuracy needed to bid more competitively and, in turn, win more jobs. Pairing a grade control system with a crawler dozer or motor grader is a great way to see a huge return on investment. Grade control is quickly being adopted on jobsites throughout the country, and the cost benefits of investing in grade control technology can enhance a contractor’s bottom line. Today, machine technology has emerged to simplify the grading process and eliminate inefficiencies. While it can be an expensive process, grading plays a critical role in laying out a mapped overview of jobsite development.

Caterpillar offers extensive operator training through Equipment Training Solutions. Otherwise, you’ll have slower return times, and your downhill dozing advantage will be reduced.Īvoid third gear in reverse unless push loading scrapers or there is an emergency.įront-to-back or slot dozing in short cuts will save on fuel costs in the long run and help prevent problems like overloading and track slip.įor small machines, that distance is about 200 feet for larger machines, it’s up to 500 feet. Lose too much dirt over the sides of your blade, and you’ll just have to redo your work. Keep an eye on the rise of material over the blade and monitor your spillage. When your blade is loaded, use the tilt to move in the direction of the pile or fill. Use dozer tilt to steer the machine while dozing.Avoid lugging or stalling your machine.Ĭat AutoCarry automates your blade lift to maintain a consistent amount of material to prevent overloading.And overloading your blade can lead to a waste of horsepower and fuel and can cause track slip. Cat Traction Control can help automatically reduce track slip to save on time, fuel and wear.
