MAGNET MARVEL.
■ I | The electric lifting magnet, while employed chiefly for handling magnetic materials, is also useful when its properties are applied to the demolition of obsolete engineering plant." In this type of work the best results are obtained by using a breaker ball in conjunction with a circular type of lifting magnet. The magnet is slung from the most convenient type of hoisting gear available, and as large a drop as possible is allowed between the breaker ball and the plant to be demolished. Work of this description was recently undertaken in a large w;orks in the Midlands, where an obsolete steam engine previously used for driving workshop machinery has been replaced by up-to-date electric gear The plant used in demolishing this engine included a 36in diameter electric lifting magnet and a steel ball -weighing 14 tons. The magnet held the breaker ball above the engine to be demolished, and when the current was switched off from the magnet the breaker ball fell on the flywheel... This process was repeated until the whole of the engine was reduced to sufficiently small proportions to be handled conveniently.
