Shears are used for cutting and demolishing steel structures, and preparing bulk scrap for further processing. The shears feature 360 degree rotation and a high force-to-weight ratio. Shears can be mounted on the boom or the stick. Shears can be mounted on a quick coupler or without a quick coupler.
