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

Both had severe rise limitations: the drum type, in the size of the drum; and the hydraulic
