Selection of electrical apparatus for cranes: Auxiliary electrical equipment for motor-operated cranes: Electric crane controllers

C. A. Bird: Referring particularly to Mr. Eastwood's paper on brakes, we might add the subject of weather-proof coils. Cranes at steel mills usually are used out of doors, and are subjected to weather conditions that are rather severe, and the design of the brake might be well considered along the same lines as those of the motor. This will refer to the linings as well.
