Types of Elevator Lift Systems
The idea behind all elevators
is the same: attach a lifting system to a compartment built into a hoist way.
But elevators get much more complicated once you introduce different kinds of
lifting mechanisms. Depending on what is most important to you – a smooth ride
or energy saver, for example – you might best be served by a particular type of
elevator and lifting system. There are a variety of different hoist mechanisms
used to lift and lower elevator cabs. The most familiar types of elevator
systems are: hydraulic, traction, climbing, and pneumatic.
Hydraulic
elevators
Hydraulic elevators are
typically used in low-rise applications (2-8 story buildings), and move up and
down via a piston that supports the elevator cab from the bottom. The maximum
traveling speed of these hoist systems is about 200 feet per minute, with the
maximum traveling height lying anywhere between 20-60 feet, dependent upon the
type of hydraulic system used. There are numerous types of hydraulic systems
including: holed, hole-less, telescopic, non-telescoping, and roped hydraulic
elevator systems.
Traction
elevators
Traction elevators use
ropes that pass over a wheel attached to a motor that sits above the elevator
shaft. These elevators are used for mid- to high-rise applications due to their
increased speeds and maximum traveling heights. There are three types of
traction elevators used today: geared, gear-less, and machine-room-less.
Climbing elevators
Climbing elevators have
their own electric or combustion engines mounted to them. You'll often find
these types of elevators used in construction areas and other work-zones.
Pneumatic

The pneumatic vacuum
elevator, or PVE, is the newest innovation in elevator design. PVE’s are
revolutionary because they do not require cables, chains, pistons, or
counterweights, but instead use the hoist way itself as part of the lifting
system. Composed of a tube-shaped cab in a tube-shaped hoist way, the pneumatic
vacuum elevator uses parts that fit perfectly together. This is necessary in
order to maintain precise atmospheric pressures above and below the cab. The
lifting action occurs when pressure is reduced above the cab, causing it to
rise to fill the void. To descend, a control valve slowly releases pressure,
creating a cushion of air beneath the cab. This makes for an energy-conscious
elevator since energy is needed almost exclusively to lift the cab and not to
lower it.
