Workers labor under the hot sun Friday at Winfield Scott Elementary School in order to install a brand new airconditioning unit. Before the new unit could be put into place, the old units had to be removed. A 110-ton crane was used to lift the old unit off the building and to place the new unit onto the roof of the building. The massive crane is called T3 because of its role in the 2003 movie 'Terminator 3: Rise of the Machines.' The Joplin, Mo.-based company, Ozark Crain Services, purchased the crane after its Hollywood debut. Tribune photo/Rayma Silvers
