Glossary of Terms
An electrical/hydraulic device on
pumping unit that controls the normal flow of oil to and from the
jack such that a slow speed is used to approach a landing and a fast
speed is used between floors.
The cab lights can be wired to turn
on only when the elevator is called and these will turn off by a
timer.
The surface within the cab, which
is met by the closed gate, is known as the strike. The particular
finish or color of wall material chosen by the designer could be
stainless, brass or plastic laminate.
This motor-driven device is mounted
on the car roof and will open the door at each landing but not the
car gate. There would be an operator on each side of the car to operate
opposite openings.
Means to move the elevator (hydraulic,
hydraulic & cable, cable, and cable with counterweights.)
The N type door lock has four electrical
switches within it known as contacts, made by the GAL Corporation
in NY. Typically this lock is used in combination with a retiring
cam.
plain carbon steel that has been
Electro-plated with a zinc alloy to create a "rust-proofing" barrier
on the base metal.(bright silver with speckled appearance)
The high strength, flexible woven
steel wires that suspend the car with rated load and possibly counter
weights
This motor device is at each door
on every landing to open that particular door but not the car gate.
This takes place by a local elevator
inspector to verify that an elevator or dumbwaiter is in compliance
with standard codes applicable to that device.
this is an Electro-magnetic device
which moves with the car along a thin steel tape for the purpose
of informing the controller about the car location
in the hoistway. It also automatically re-levels the car if it moves up or down from floor level
in the hoistway. It also automatically re-levels the car if it moves up or down from floor level
A plastic like material giving appearance
of deep rich paint; very durable and hard, bonded to both sides of
Particleboard.
This is the door through which the
passengers gain access to the elevator from the building. Being metal
gives the advantage of having the proper fire rating and the flush
fit of the frame to the hoistway inside wall gives the correct running
clearance.
This device actuates the safety
by sensing that the car is traveling too fast downward.
Granulated pinewood that has been
bonded together under high pressure and temperature.
(Programmable logic controller)
a control device that uses a programmable microprocessor and is typically
programmed IIEC 61131 programming languages. The number of I/O ports
they provide often categorizes PLC. This device controls the motion
of the elevator based on the call of the passenger.
A motor-driven device mounted on
the car roof, which opens and closes the car door automatically.
This electrical/hydraulic device
is attached to the control valve to scene when there is low pressure
in the oil line and prevents the car from being operated.
A relay is an electromagnetic switch
used to control multiple circuits on the elevator. There is many
of these type switches in a typical controller.
This electrical/mechanical device
is used to activate the door locks when the elevator is at floor
level and it will retract when the elevator is moving between floors.
This hydraulic device is attached
to the inlet of the jack and it will limit the speed of car decent
if an oil line should brake open.
A mechanical device, which will
stop and sustain the elevator and its rated load if either of the
hoisting cables becomes slack or breaks.
This is a heavy-duty pulley, which
is used with the hoist cables so as to drive the cables by traction
or suspend the cables. In either case the direction of the cable
is changed and this device supports the weight of the elevator.
This is the gate track on the floor
of the cab, which serves to guide the gate. It is typically metal
located between the floor of the cab and the threshold of the building
door.
An electrical/hydraulic device on
pumping unit that controls the normal flow of oil to and from the
jack such that a single car speed occurs up or down.
High carbon, low iron content, high
nickel resulting in a material, which is corrosion resistant and
has a smooth pewter (silver-gray) appearance.
The stationary steel members of
an elevator system who guide the car vertically through the hoistway
and resemble a "T" in a cross-section view.
A horizontal crosspiece over a gate
that is attached to the ceiling and two adjacent walls of the cab
that serves to hide the upper gate track and complements the strike
and return portion of the cab interior. Since gates are normally
80 inches tall and cabs can be 7 or 8 feet tall the transom makes
up the height difference for the opening.
