Hitachi Rolls Out Factory-Integrated Grade-Control Features on Three of its Excavators.

Hitachi has rolled out options for factory-integrated grade-control technology on its ZX210-6, ZX210LC-6, and ZX350LC-6 crawler excavators. They include 2D Grade Control and Solution Linkage 3D Grade Control, which allow an operator to set a grade and hold it.

Hitachi offers customers a total of four options for grade-management technology: 2D grade guidance, 3D grade guidance, 2D grade control and Solution Linkage 3D grade control.

“We gave a sneak peek of Hitachi’s grade control technology at Conexpo last year,” said Justin Steger, solutions marketing manager, site development & underground, Hitachi Construction & Mining Division. “It’s thrilling to share this solution with our customers for increased efficiency. We know grade-management technology is the future of the excavator industry, and we’re glad to provide a variety of options for our customers.”

With the technology, the machine controls the boom and bucket as the operator handles the arm. This is especially useful as it reduces the need for multiple passes to achieve the correct grade. Likewise, less experienced operators are able to achieve the correct grade more efficiently while a crew member who previously had to check for the grade can now be assigned elsewhere on the worksite, Hitachi says.

Solution Linkage 3D Grade Control with Global Navigation Satellite System (GNSS) controls position and elevation with respect to a global reference, and the 2D Grade Control manages the elevation of the cutting edge in relation to a benchmark. The 2D Grade Control technology can also be upgraded to 3D Grade Control, through Hitachi excavator dealers.

“Our 2D Grade Control and Solution Linkage 3D Grade Control unite advanced grade technology with the smooth hydraulics and fast cycle times of Hitachi excavators,” Steger said. “It saves time and helps make good operators great.”

With an over-dig protection feature, the new grade control technology also lowers the likelihood of over-excavation by preventing the machine from digging past a defined surface or depth. The Virtual Front feature hydraulically limits and automatically stops the bucket cutting edge from contacting the front of the machine at a selectable distance.

Additionally, operators can set virtual boundaries helping prevent damage when working around job site obstacles. Virtual Ceiling, Virtual Floor, Virtual Swing, and Virtual Wall features provide visual and audible alerts to the operator as the machine approaches an adjustable set point.

The systems are also fully supported by Hitachi excavator dealers. Machine integration helps ensure that keep components such as sensors and harnesses are protected. System data from all options works with ZXLink telematics for analysis, so the machine’s health can be monitored.
