Trimble ‘advancing’ machine control
By Andy Brown02 April 2020
Trimble has released the latest version of its earthworks grade control platform introducing a host of new features, including for dozers and excavators.
Earthworks Grade Control Platform version 2.0 introduces Horizontal Steering Control for dozers. This is said to automatically control the machine to follow any horizontal alignment such as a back of a curb, breakline, roadway centerline or bottom of slope, without operator assistance.
According to Trimble, this allows the operator to focus on the grade and machine productivity rather than worrying about steering, reducing operator fatigue and errors. It enables the machine to follow the horizontal guidance from the 3D model, providing operators increased awareness of their surroundings, better accuracy and improved productivity with decreased overlap and fewer passes.
Another first is Augmented Reality for excavators. This enables users to easily understand 3D models, cut/fill information, slope data and other bench points and reference points on the in-cab display in context, without the need to interpret complex 2D plans or stakes.
Using a camera mounted on the outside of the machine, operators can view 3D models in a real-world environment at a true-life scale, in the context of existing surroundings. On the Trimble Earthworks display, the model is overlaid onto the existing ground giving the operator a better understanding of the work that needs to be done. Visibility of the bucket gives operators better situational awareness to be able to keep surrounding people and objects safe.
“Trimble is on the forefront of innovation and cutting-edge technology along the path to automation,” said Scott Crozier, vice president, Trimble’s Civil Engineering and Construction. “Using proven steering technology from Trimble Agriculture, we are continuing to advance construction machine control yet again.”
Trimble Earthworks is also now available for compact grading attachments with dual GNSS, single GNSS and total station guidance options.
