To quickly assess the difficulty of the text, read a short excerpt:
The governor is driven by a three-rope drive, dependence not being placed on a single rope or belt. A device has been installed to call attention to broken strands, which strike a board hinged to the pulley-guard, throwing the board back, and thus notifying the engineer. All overhead cranes are provided with railed walks on both bridge girders, extending the entire length of the crane. The trolley, or carriage, is floored over and pro- vided with a railed walk. Hoists are equipped with a limit ...switch, which prevents overwinding, breaking of the cable, and dropping the load on the workmen. Each crane has a safety switch, cutting off all power and making it impossible for an absent-minded operator to forget that men are working above. When a man goes on top of a crane he pulls out this switch and attaches a sign reading " Danger Do Not Move. " A box is provided on the crane bridge for tools, oil cans, and other articles. Ex- tending out from the truck-wheels of cranes are brush guards to warn a person resting his hand on the rail of the approach of the crane, which he might fail to note because of other noises.
