For the design of his tower, there was virtually no experience in structural history from which Eiffel could draw other than a series of high piers that his own firm had designed earlier for railway bridges.

...During the previously mentioned studies of high piers undertaken by the Eiffel firm, it was established that as the base width of these piers increased in proportion to their height, the diagonal bracing connecting the vertical members, necessary for rigidity, became so long as to be subject to high flexural stresses from wind and columnar loading.

...By the last quarter of the century, a continuous series of improvements in the valving, control systems, and safety features of the steam machine had made possible an elevator able to compete with the subsequently appearing hydraulic systems for freight and low-rise passenger service insofar as smoothness, control, and lifting power were concerned.

...The Backmann design for the upper elevators was based upon a principle which had been attractive to many inventors in the mid-19th century period of elevator development-that of "screwing the car up" by means of a threaded element and a nut, either of which might be rotated and the other remain stationary.

...In the plan as first presented, a ground-based steam engine drove the frames and rollers through an endless fly rope-traveling at high speed presumably to permit it to be of small diameter and still transmit a reasonable amount of power-which engaged pulleys on the cars.
