Clamshells are preferred for free-flowing bulk commodities; orange-peel grapples for mixed or irregular cargo; magnets for ferrous scrap. Rotating versions improve placement accuracy into hoppers, trucks, or railcars. Dust-control features and sealed designs are important in environmentally sensitive port and terminal locations.  Alaska Craft can provide any of these tools needed including self-contained units if your current dockside crane does not have line power or controls.
