Most of the control devices which are required in a foundry do not differ very materially in their functions from control devices in other industries. However, they have to encounter an unusual degree of dirt. Proper enclosing cases and the latest types of safety protection are advantageous. The crane requires a special kind of control. The difference between alternating-current control and direct-current control is discussed and it is shown that for most cases, where cranes are properly selected and arranged, there is no need of converting alternating current into direct current to accommodate foundry cranes.
