opposite ends of the cables to which the car is fastened.

A

counterweights

23
Q

Is the vertical passageway to the car & counterweights.

24
Q

Are available with pre-engineered units with speeds of 500 to 1200 ft/min. They offer the
advantages of:

A

Gearless Traction Machine

25
Q

Are designed to operate within the range of 100 to 450 ft/min, restricting their use to mediumrise building.

A

Geared Traction Machine

26
Q

Safety is designed to stop an elevator car automatically before the car speed becomes
excessive. The action of one such device is controlled by the _______.

27
Q

Their purpose is not to stop a falling car but to bring it to a partially cushioned stop if it would
over travel the lower terminal.

28
Q

Are located a few feet below and above the safe limits of the elevator car.

A

Final Limit Switches

29
Q

CRITERIA FOR ELEVATOR SELECTION

A
  1. [INTERVAL
  2. [HANDLING CAPACITY
  3. [TRAVEL TIME
30
Q

The elevator solution involves transporting large groups of people from
the street lobby to an upper lobby called a sky plaza. At this time the
passengers transfer to another elevator to continue their upward journey.

A

Sky-Plaza Systems

31
Q

an old technique, recently revise to answer the needs of tall buildings .
the double deck car increases shaft capacity, decreases the number of
local stop and increases the rental area available.

A

Double-deck elevators

32
Q

In contradiction to the traction type, this hydraulic or plunger elevator
Is raised and lowered quite simply, by means of a movable rod rigidly
fixed to the bottom of the elevator car.

A

Hydraulic Elevators

33
Q

It is a conveyor transport device for transporting people, consisting of individual, linked steps that
move up or down on tracks, which keep the treads horizontal.

A

Escalators

34
Q

It is used to do just what its name implies: to elevate, or lift, freight, or goods. It is built to carry
goods rather than people, though some do both to allow operators and those loading goods
along for the ride.

A

Freight Elevators

35
Q

There is a fresh air intake housed on the roof contains a blower to drive
air downward through escalator floor openings, while the exhaust fan
on the roof creates a strong draft upward through an exhaust duct, this ducts
in turn draws air from the separate ducts just under the ceiling of each
moving stairway floor opening.

A

Sprinkler Vent

36
Q

Four methods of affording protection in case of fire near escalators
are available:

A
  1. [rolling shutter

38
Q

It is a device with an incline limited to 15 degrees, where vertical
motion is as important or more important than the horizontal component

A

Moving Ramp

39
Q

It is a vertical transport vehicle that efficiently moves people or goods between floors of a building

A

Elevator or Lift

40
Q

It can operate without the use of cables or hydraulics.

A

Pneumatic Vacuum Elevators

41
Q

An elevator cab is typically borne by six or eight hoist cables, each of which is capable on its
own of supporting the full load of the elevator plus twenty-five per cent more weight

A

Cable-borne elevators

42
Q

It uses the principles of hydraulics (in the sense of hydraulic power) to pressurize an above ground
or in-ground piston to raise and lower the car.

A

Hydraulic Elevator

43
Q

Elevators and lifts used in mines, The method involves destructive testing of a segment of the
cable.

A

Mine-shaft elevators

44
Q

All elevators, whether traction or hydraulic, require a machine room to store large electric
motors (or hydraulic pumps) and a controller cabinet. This room is located above the hoistway
(or below, for hydraulic elevators) and may contain machinery for a single or a group of
elevators.
