Not all cranes go to work on construction jobsites.
You are looking at a group of researchers floating above James Cook University's Daintree Rainforest Observatory in Australia. Here, researchers are able to access every level of the rainforest with the "Jungle Giant," a 47 meter high Liebherr crane installed 20 years ago. The Jungle Giant's birthday makes it the longest-standing crane in Australia. The crane has assisted researchers in important studies of tree physiology, rainforest ecology, and how a drought might affect the region. Not long after it was set up, a Category 3 cyclone struct the area but the observatory says the crane remained standing strong.
