GMK7550 helps restore historic theatre
A Grove GMK7550 all-terrain crane helped dismantle a dome in the roof of The Tobin Center for the Performing Arts? in downtown San Antonio, Texas. Dismantling the roof of the landmark, 1920s-era theatre is one part of the $130 million renovation project. The four roof sections, which ranged in weight from 5 to 10 US t, were dismantled in place and lifted out by the GMK7550. The Grove GMK7550 was rented by Texas Crane Services in San Antonio, Texas. Texas Crane Services crane operator John Dalton said they chose the GMK7550 primarily for its reach. The GMK7550 features a 197 ft main boom, but when rigged with a luffing jib and inserts it can achieve a maximum tip height of 430 ft.

For the Tobin Center job, Texas Crane?s GMK7550 operated at radii that ranged from 90 ft to 180 ft, the GMK7550 was configured with 115 ft of main boom and 161 ft of luffing jib. The crane was also configured with Grove?s Mega Wing Lift attachment to give greater rigidity to the boom and to accommodate increased counterweight. It is particularly useful for jobsites such as this one where the crane was not able to be placed very close to the pick site.
