A cooperative deal between Komatsu, Becker-Warkop and Hydrotech has resulted in the delivery of 385 new longwall-powered roof supports to an Alabama operation.
The new supports, according to Komatsu, include Joy’s Faceboos RS20 support controls. While the trio did not confirm the identity of the recipient mines, they did collectively confirm that the first face began operation in July and the second face is undergoing installation.
“The longwalls enter operation at mines which have seam heights of 45 inches and 53 inches, respectively, and the 1,700-millimeter (67-in.) wide supports feature a maximum operating height of 2,946 mm (116 in.) and have 380-mm bore legs,” the OEM said.
Komatsu has provided powered roof supports to the producer in the past, though the new delivery is the first in collaboration with Becker-Warkop and Hydrotech.
Other longwall equipment at this mine supplied by Komatsu includes three Joy 7LS1D shearers and three armored face conveyors (AFCs), including the first U.S.-sourced Joy panline.
