Minneapolis, Minnesota-based Mortenson Construction is using a trio of Manitowoc Grove GHC55 telescoping crawler cranes to perform a new method of solar panel assembly and installation at the Alamo solar farms in Uvalde, Texas. Traditionally, solar panels have been constructed by adjoining several 2 ft by 3 ft modules, each requiring a separate lift. The GHC cranes operate with 100 percent pick and carry capability, increasing efficiency on the jobsite. This allows Mortenson to combine 15 or 20 modules together on a table and then carry them into place to lift about 20 ft in the air for installation. The heaviest picks weigh up to 3.5 USt.
“We have chosen these telescoping boom crawlers because, as a rule, Mortenson will not pick and carry loads on cranes with rubber tires—especially on a remote job site with off-road terrain,” said Steven Klatt, crane manager with the company. “With 100 percent pick and carry, we can prefabricate the solar panels and run the cranes back and forth from the trucks to where they are placed on the solar farm. The crawler tracks easily handle the terrain, and the GHC’s booms withstand the wind. This has increased our efficiency.”
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
