How do you create a 3D machine avoidance zone and upload it to Trimble earthworks

1. 4m Around the overhead electric line

2. 5m off the edge of the live rail 

Unfortunately you can't. Trimble Earthworks only support 2D avoidance zones.

I believe that to be incorrect as there is a new module on earthworks which allows TMC to be added, and has been done in New Zealand

That looks like some custom software they created for that project. Definitely not earthworks. 

Hi Gavin,

Lasse and Matthew can correct me but Trimble Marine construction is a standalone program. It probably uses same sensors as Earthworks but not connected to the Earthworks program. TMC program looks very similar as PDS2000 that also can use same sensors as Earthworks (Trimble) but completely different program.

Didn't the press release stated that they installed dual mast GPS on a crane?

If that's the case than they could have defined hook or boom or bottom of the load as the "cutting edge" and have simple, template based 3D model for the 3D avoidance zone.

"Onboard, a touch screen shows the driver a 3D view of the crane boom’s proximity to the closest conductor and the closest section of the safety envelope... "

You're in FILL, your'e safe with fill value showing vert. dist from the "3D avoidance zone".

Energised power lines could be alignments providing real time offsets.

Doesn't transpire to me that they were using 3D model + 3D avoidance.

But that is just my guess.

We used TMC with Trimble SPS855/555H and LR sensors on the cranes in Wellington.  The primary antenna on the end of the boom and the heading on the cab.  We then created line models of the powerlines in their highest (lowest elevation) potential sag state and positions if the wind had made them swing then had an avoidance zone from these lines to any point of a 3d model of the crane.  You can choose two different alarm zones, one say 10m from zone and one 5m from zone. 

It is possible to use the EC520 to provide position information to TMC but not Earthworks itself.

This is one for the Machine guys to answer. Last week at ConExpo they were showing some Augmented Reality stuff on the machine that may help here (Read SiteVision in the Cab on Earthworks) so you can see Virtual Utilities in the 3D Graphics of a Machine. 

They will have to answer what is possible today or coming soon, as I don't have all the latest info in that area.

Thanks, Alan

Just to let you know that the subcontractor has upgraded his trimble earthworks machine control with TMC 3d avoidance (get fitted in the next couple of weeks)

We are just trying to set up the files ready for export to TMC / Earthworks
