On a project located in O’Hare International Airport, La Grange Crane employed a Grove GMK5275 all-terrain crane to build an underground water detention system in Rosemont, Ill. The 275-ton crane lifted a series of 9-ton precast segments to construct the system, which will keep stormwater runoff under control for a planned commercial development.
Since the job took place near the airport, crane operators for the Hodgkins, Ill.-based company had to stay within strict tip-height limits, as per FAA regulations. This meant staying below 100 feet to avoid interference with the incoming paths of commercial airliners. Contractors also had to work around a pre-existing pipe situated inside the jobsite, which called for a crane that could alternate between two lift locations with efficiency.
Judi Mooncotch Jr., president of La Grange, said the GMK5275 was ideal for the job because of its mobility and the smooth operation of its boom.
“This crane was perfect because it allowed us to stay low, telescope out, and make all the necessary lifts without exceeding tip-height constraints,” she explained. “Mobility was also a factor. It’s not easy moving a crane when you also have to coordinate the delivery schedule of nearly 1,500 tons of precast, but the GMK5275 enabled us to get the work done on time.”
