Question 2

A tracked weight which is suspended from cables and moves within the
guide rails along the hoistway walls. The counterweight will be equal to the weight of the
elevator car plus 40 percent of the anticipated live load. (passengers)

Answer 2

counterweight

Question 3

Constructed within the hoistway, an elevator car consists of a cage of light
metal or metal supported plywood panels within a heavy steel frame. This frame includes a
SAFETY PLANK which forms the bottom and the CROSSHEAD from which an elevator car is
usually suspended. The ELEVATOR CAR DOOR moves with the car.

Answer 3

elevator car

Question 4

A keyhole in the HOISTWAY DOOR that accepts a LUNAR KEY
which is used to trip the hoistway door release. Generally, only the top and/or bottom hoistway doors have this feature

Answer 4

ESCUTCHEON TUBE-

Question 5

A shaft that encompasses the elevator car, generally serving all floors in
buildings of modest height. In high rise buildings exceeding about 20 stories, the elevator
hoistways may be BANKED with one bank serving only the lower floors and one or more banks which serve only intermediate or top floors. The elevator cars in upper banks will travel in a BLIND HOISTWAY until they reach the designated levels they serve. A blind hoistway has no hoistway doors on the lower floors not served by the elevator car.

Answer 5

hoistway

Question 6

The hoistway door locks, called INTERLOCKS because of their electrical and
mechanical interconnection. In normal operation the car cannot move until all interlocks are closed.

Answer 6

Interlock

Question 7

A hoistway door opening device which is inserted into the escutcheon tube and
turned or pulled down to trip the release mechanism. An assortment of Lunar Keys are carried by Squad One and all Truck companies.

Answer 7

Lunar key

Question 8

Generally located above the hoistway. However, there are exceptions
which are covered under “ELEVATOR TYPES”. A machine room generally contains a hoisting
machine, a controller, a motor generator and speed generator. The main electrical disconnect is also housed in this room

Answer 8

machine room

Question 9

A mode of operation activated either by smoke detectors or the KEY RECALL
SWITCH, and results in the return of all cars (except those out of service or in independent
service) to the designated level, usually the lobby.( see PHASE 1 OPERATION in PART
THREE of this bulletin )

Answer 9

Phase one

Question 10

A steady beam of light shown between the Hoistway and Car
doors, horizontally at about knee level. This light beam is sent to a receiving unit and is designed to stop the closing motion of the doors when the beam is broken, and immediately reverse the doors until they are fully open. This feature is overridden when the car is in PHASE TWO operation.

Answer 10

Photo electric eye

Question 11

A set of three wheels that roll against the guide rails. Roller guides usually
mount to both the safety plank and the crosshead, one set on either end of each beam. These guides keep the car in contact with the guide rails and prevent sway or lateral movement

Answer 11

Roller guides

Question 12

A motion sensing device, such as a frangible bulb, installed on the
Machine Room wall which renders a car inoperable. Seismic devices are required on all traction installations constructed after 7-1-93 where the speed of the car is greater than 150 feet per minute. These devices should only be reset by an elevator technician. If activated, it is an indication that the installation may be unsafe. i.e. counterweights out of their track, loosened mounting bolts, etc

Answer 12

Seismic device

Question 13

To give you some idea as to the stopping distance, a car whose rated speed is up to 125 feet per
minute should, in free fall, stop within one foot three inches. A car rated to 500 feet per minute
would stop within five feet eight inches. Elevator cars that have a rating of 1500 feet per minute
could require up to forty feet to stop.

Question 14
