BRIDGES Ӏ SECTOR SPOTLIGHT
Who: Lane Construction Corp/ South Carolina Department of Transportation / Link-Belt Cranes. What: Two Link-Belt telescopic crawler cranes are constructing two bridges over a river to replace preexisting overpasses along Interstate 20 in South Carolina, USA. Where: Wateree River, Kershaw County, South Carolina.
North Carolina-headquartered construction company Lane Construction Corporation is utilising two Link-Belt TCC-2500 telecrawlers to build two bridges over the Wateree River in South Carolina. The bridges will replace two preexisting overpasses along Interstate 20 as part of a bridge rehabilitation project for the South Carolina Department of Transportation. Renting the TCC-2500s from
Lomma Crane & Rigging, of Bridgeville, Pennsylvania, Lane first used the TCC-2500s to drive piling to build temporary trestles on both sides of the river. As the river is a navigable waterway, and requires maintained access through its middle, the Lane work crew is using the TCC-2500s concurrently, one on each trestle, to begin foundation work for
the replacement bridges. Although a traditional lattice boom crane was used to start the project, Lane project director Eric Pruemer soon realised it was not optimised for the tight job site, stating it was constantly in the way and difficult to move efficiently. He says the TCC-2500s’
manoeuvrability was exactly what was needed to do the job right. “These allow us to easily go underneath the bridge back and forth to facilitate work on both the outside and the median of this bridge,” he said. “The cranes are very sleek, and they work very well.” Pruemer notes that the cranes’ ability to quickly retract and extend their booms mean they can travel under each bridge easily and work on either side when
driving the steel tubular pile needed to construct bracing for the existing bridges throughout the demolition process, saving the crew time and money. “Without that, it would’ve been a half
day to a day of dismantling the crane, moving it over, and then reassembling it,” Pruemer says. The TCC-2500s’ ability to work and
manoeuvre efficiently in close quarters made the difference to Lane, says Link- Belt and it is now using them exclusively for the rest of the job, as the company needs to keep road and water traffic open throughout the duration of the project. The cranes are likely be on-site for
between six to eight months. A video of the project can be seen here:
