Abstract
A suspension frame for supporting a nose-tilt molten metal ladle includes end-to-end vertically arranged hydraulic cylinders above the ladle and totally protected within an elongated hollow enclosure. One of these cylinders is connected to an overhead carriage and operates to raise the suspension frame and the ladle as a unit. The other cylinder is connected to the ladle such that it raises the ladle relative to the suspension frame, causing the ladle to tilt about a pivotal connection at the ladle spout. The pouring device is completely self-contained with the hydraulic fluid reservoir, the hydraulic pump and motor, and a rechargeable electric storage battery for powering the pump motor all being supported on the suspension frame. Adjustment is provided to permit selection of the basic vertical position of the ladle within the suspension frame.
