Caterpillar's S365B and S385B Mobile Shears, with jaw openings of 33.3 and 34.6 inches, respectively, are designed for scrap processing and demolition. Cat says these tools provide excellent cutting capability along the entire jaw length. For scrap processing, Model S365B is recommended for boom mounting on Cat 330C-L or 345C-L excavators; and for demolition work, stick mounting on the 365C-L is suggested. The larger S385B shear can be boom mounted on the 345C-L and 365C-L, or stick mounted on the 385C-L. The shears feature a heavy-duty rotation system and an integrated speed valve designed to reduce cycle time to less than 8 seconds.
