Discussion on “a large electric hoist” (Sykes), San Francisco, Cal., Sept. 17, 1915. (see proceedings for August, 1915)

Graham Bright: One remarkable thing about the hoist described in Mr. Sykes´ paper is that although it is much larger than anything heretofore built in this country, the actual performances obtained in operation are strikingly close to the guaranteed values given by the manufacturer. This shows clearly that the art of hoisting and hoist calculations are being more thoroughly understood and the performance of even the largest hoists can be foretold with certainty.
