Abstract
A material moving system is disclosed for use in a plant such as a metal foundry. There is an overhead gantry for moving a main hook and auxiliary hook. The main hook carries a container such as a scrap charge bucket. The auxiliary hook carries a multi-function auxiliary tool such as a magnet with a tool hook affixed to the magnet. The scrap charge bucket carries a target member on a saddle on the outside of the bucket. The bucket also has a hold out stand that positions the target member for easy accessibility. The target member is attached to actuator cables that are attached to clam shell bottom members of the scrap charge bucket. The auxiliary tool may be used to lift and pull the target member to open the clam shell members without removing the magnet from the auxiliary hook, saving time. The hook on the magnet is positioned so that the hook does not damage the scrap metal bins or electric arc furnaces when the magnet is used for its usual purposes. The target member is shaped so that its position on the magnet is secure when it is lifted off of the saddle support; it has two plates with edges that complement the shape of the magnet, and with a center of gravity that tends to hold the target member against the magnet.
