Pre-Cast Concrete Panels Lifted by Link-Belt
In Henrico, Va., a new 216,000-sq.-ft. warehouse is being built by Becknell Industrial at the Richmond Airport Distribution Complex. The developer, which specializes in industrial properties, is anticipating an influx of cargo for the state capitol in the coming years, and the 900-ft.-long facility will prepare Becknell to receive goods. Located on 17-plus acres, the pre-cast concrete building will have 20 dock doors, 25 tractor-trailer stalls, and a 60-ft. loading bay.
Extreme Steel Crane & Rigging Inc.,Warrenton, Va., placed more than 190 pre-cast concrete panels during the building’s construction. In order to lift and place the 27,000-lb. panels, which measure 8 ft. wide and up to 38 ft. tall, the company used a 210-ton Link-Belt ATC-3210 all-terrain crane. On average, the Extreme Steel Crane & Rigging Inc. crew lifted and placed 12 panels each day. To help rotate the slabs, crane operator David Haley uses the 12-ft. heavy lift stowable fly jib, and a two-line, one load lift procedure that comes standard on the Link-Belt ATC-3210. The fly is rated at 34 tons of capacity.
“Before [using the fly jib], we would have had two lines over the main head sheaves which means the blocks would get too close and hit or banged up against each other,” said Haley. “This fly makes the procedure so much easier because it keeps your lines separated. It’s nice and quicker for me with less line entanglement.”
The radius for lifting the concrete slabs ranges from 40 to 70 ft. with the boom extended anywhere from 135 to 168 ft.
