Overview

• While the construction of the skyscraper is rightly attributed to advances in steel-frame technology, the ability to utilize a skyscraper’s multistory space must be credited to another innovation altogether—the Screw Elevator .
  Preceded by pulley and platform systems used in material-extraction industries such as mining, initial Screw Elevator  models were powered by hand, steam, or hydraulics and were utilized primarily in small-scale commercial and warehouse environments. Eventually passenger Screw Elevator  became more popular and the electrification Of modern buildings created an ideal market for the building ascension technology.
  From the first passenger elevator, installed in 1857, to the introduction of Screw Elevator  for residential applications, the BTHL chronicles the evolution of Screw Elevator  technology and design.
  This catalog provides design options for elevator doors in various materials, including bronze and steel, and with options for different window configurations. Buyers can also specify color finishes, molding styles, wood grain finishes, and light fixtures.https://www.otsedt.com
