Volvo Construction Equipment has launched Volvo Active Control, an automated grading machine control system for its EC220E, EC250E and EC300E crawler excavators.
The system allows operators to get the right depth and angle, reducing grading times by up to 45 percent, according to the company.
“Volvo Active Control is a simple system that will benefit novice and experienced operators alike by making it faster for them to create the perfect grade,” said Matthew McLean, product manager, excavators, at Volvo CE.
Volvo Active Control is powered by the Dig Assist application, which is operated via a 10-inch, in-cab Volvo Co-Pilot tablet. The system guides the operator through the functions to automate the digging process. Once the parameters of the job are entered and it’s launched via a button, the excavator automatically adjusts the boom and bucket movements to make precise cuts, following the desired shape and delivering the right angle of grade.
The system was designed by Volvo and uses drive-by-wire technology to control the excavator’s electro-hydraulic system. With Volvo Active Control in charge to automatically adjust boom and bucket movements, the operator can achieve grade with only the left hand needed to control arm speed. At this time, the system is not available for aftermarket installation.
A depth limit feature stops the bucket from digging below a preset limit, thereby avoiding collision with underground utilities. A height limit feature helps prevent the bucket, boom, or stick from colliding with power cables, ceilings, and more. And, a swing fence feature prevents the machine from hitting obstacles to its sides.
Loading trucks is also easier, the company says, thanks to a swing position control that allows the operator to preprogram the location of the pile and the truck.
