Assistance Technology:
Who Needs It?

If you’re in the market for a new car, you may be looking at a lot of options that weren’t available even a couple of years ago—things like adaptive cruise control, lane departure warning systems, blind spot detection and automatic parallel parking. They’re known as Advanced Driver Assistance Systems, and although some view these features as overkill, others expect them to become commonplace very soon.

Some construction equipment manufacturers are applying assistance technology too, introducing automated grading systems that don’t require a full-blown investment in GPS infrastructure. These systems not only provide visual guidance for the operator—an in-cab image showing where to cut and fill—they also control blade or bucket movement, freeing the operator to focus on other tasks.
 

WHAT'S AVAILABLE?

Some new dozers use assistance technology to control blade angle. The operator simply sets the angle on the monitor in the cab, then lets the system maintain that angle while the machine moves over the ground. The operator still controls the height of the blade manually, but is no longer required to make constant adjustments to its angle. The result is faster, more efficient grading with less fatigue, rework and fuel.

Assistance technology is also being used on excavators to automate selected boom and bucket functions. The operator enters a target depth on the monitor, selects “auto” and starts working. When the bucket gets within a few inches of target depth, the assist technology takes over, automatically adjusting boom movement and bucket roll to maintain a constant bucket angle through the dig. Again, the result is quick, accurate, cost-effective grading.
