GOOD GRADES What’s new in grade control solutions

emote monitoring, wireless data transfer (WDT) and automatic/ semi-automatic functions are becoming increasingly common in grade control systems. Other grade control trends include a clamour for 3D solutions even when a cheaper, simpler 2D solution might suffice. “2D works in two dimensions usually with a rotating laser as its benchmark. It’s perfect for flat pads, simple slopes, maybe a driveway or parking lot. 3D uses GPS [or GNSS] satellite technology or a total station for more complex operations with contours, such as a super elevated turn on a highway, maybe a golf course… A lot of customers think they need 3D but, in many applications, 3D may be over the contractor’s budget or overkill,” says Richie Snyder, marketing manager for precision solutions and telematics, CASE Construction Equipment.

“2D applications can have a tighter tolerance… [Also], 3D does not necessarily always work inside tunnels — you have to see the satellites. So, a 2D application would work there. Then, there’s the initial investment. [With 2D] you don’t need a base station. You might just need a laser transmitter,” adds Scott Hagermann, senior market professional in CatGrade Technologies at Caterpillar. Wireless data transfer meanwhile, can be used to update machines and operators to changes in design or work conditions. Connectivity also enables remote support, from construction headquarters, a dealer or manufacturer. “With these technologies, support is as important as the initial purchase,” says Sean Mairet, product marketing manager for grade control at John Deere. “If something goes wrong or the setting seems goofy [it’s beneficial if someone can] remotely get into
that machine and help the operator.” A final trend centres on user-friendliness. Simple displays, clearly identifiable screen icons and easy-to-follow instructions are now the norm. Intuitive grading controls simplify operations for older operators who didn’t grow up with technology while reducing the learning curve for younger workers with limited job experience. “Technology is obviously something that’s helping bridge some of the gaps with workforce availability,” Mairet says. Come what may, it seems pretty that clear grade control technology is here to stay. In addition to allowing operators to make consistently make grade, these solutions save money and resources. “With grade control, you don’t need as many supporting people grade-checking and setting up stakes and all,” Clark says. Here’s a look at what’s new and/or noteworthy in grade control.
