The Basis of Elevatoring a Building

EARLY POPULATION Before any thought is given to the elevators in a building, a thorough and detailed study must be made of how people will arrive at the building, occupy that building, and move about the building. Occupancy is an obvious prerequisite to the design and size of the building itself. It must be expected

Elevatoring is the analysis of the requirements of vertical transportation of people and materials in a building, under all operating conditions. Such transportation requirements may be studied from a compatibility aspect, as in an office building from a function aspect, as in a hospital or from a merchandising point of view, in a department store.

HYDRAULIC ELEVATORS A third major type of elevator in use today is a modern version of the hydraulic elevator. Most hydraulics are direct-plunger-driven from below (the cylinder extending into the ground as high as the elevator rises), and the operating fluid is oil moved by high- speed pumps rather than water under pressure see the

GEARED TRACTION MACHINES As the name implies, the geared traction elevator machine utilizes a reduction gear with a high-speed motor to drive the traction sheave. A high-speed ac or dc motor drives a worm and gear reduction unit, which in turn drives the hoisting sheave, the net result being the slow sheave speed and high

Gearless Elevator Traction Description The preceding brief discussion of early elevator history introduced the traction-type elevator. The first high-rise application of this type of elevator was in the Beaver Building in New York City in 1903, followed by such notable installations as the Singer Building (demolished in 1972) and the Woolworth Building. These elevators were

TRACTION ELEVATORS Description: Up until about 1903, either drum-type elevator machines, wherein the rope was wound on a cylindrical drum, or the hydraulic-type elevator (the direct-plunger hydraulic or the roped hydraulic machine) was the principal means of hoisting force. Both had severe rise limitations: the drum type, in the size of the drum; and the hydraulic

The beginning of the story EARLY BEGINNINGS Since the time man has occupied more than one floor of a building, he has given consideration to some form of vertical movement. The earliest forms were, of course, ladders, stairways, animal-powered hoists, and manually driven windlasses. Ancient Roman ruins show signs of shaftways where some guided movable

Comments Off on Elevator- Lift : definition and history

Definition: An elevator (US and Canada) or lift (UK, Australia, Ireland, New Zealand, and South Africa) is a type of vertical transportation that moves people or goods between floors (levels, decks) of a building, vessel, or other structure. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a
