Komatsu, Becker-Warkop, and Hydrotech deliver roof supports for longwall coal producer

The first face began operation in July and the second face is undergoing installation. While Komatsu has provided powered roof supports to this producer in the past, this is the first solution supplied in collaboration with Becker-Warkop and Hydrotech.

The new Joy-designed supports also include Joy’s Faceboss RS20s roof support controls. The longwalls enter operation at mines which have seam heights of 45 in. and 53 in. respectively, and the 1700 mm wide supports feature a maximum operating height of 2946 mm and have 380 mm bore legs.

Other longwall equipment at this mine was supplied by Komatsu including three Joy 7LS1D shearers and three armoured face conveyors (AFCs), including the first US-sourced Joy panline.
