The first electric crane over built in
the United States has just been intro
duced in the foundry of f. Z. Allis d
| Co., of Milwaukee. Wis. 1t is n non
derous affair, weighing thirty tons and
is capable of lifting and carrying to anv
part of the foundry, with case, weight
OF twenty-five tons. The crane is n
bridgelike affair, suspended on track
built on each side of the foundry, near
the ceiling. 1t is provided with three
electric motors. One moves the crane
from one end of the foundry to the other.
another moves the carriage with which
the crane is provided from one side of
the foundry to the other, and the other
runs the lifting machinery. It's advan

cage, which it resembles somewhat. is a
saving of power and the wear and teal

crane know is in an English foundry.
