The US Federal Aviation Administration has a new radar to use as its primary source of weather information at Midway airport, Chicago. For its construction, lifting equipment was supplied by Imperial Crane of Bridgeview, Illinois. Imperial supplied mobile cranes ranging from 20t to 270t capacity to erect the tower, which is known as a Doppler Radar. The photograph shows the boom of a Grove TMS 870 truck crane lifting the radar dish into the tower. For this job, it was rigged with 42m of main boom and 17m of jib. The crane was working at an 18.3m radius and the dish weighed 1.6t.
Imperial was also recently called on to lift an 11.8t section of the hull of The Titanic, which is on display for six months at Chicago’s Museum of Science & Industry. For this job, a Krupp KMK 5175 was used.
