E A LATO R

Escalator is a moving staircase

a conveyor transport device for carrying

people between floors of a building. The

device consists of a motor -driven chain

of individual, linked steps that move up or

down on tracks, allowing the step treads

to remain horizontal.

COMPONENTS OF ESCALATORS

Landing platform: The two platforms

house the curved sections of the tracks,

as well as the gears and motors that drivethe stairs.

The top platform contains the motor

assembly and the main drive gear, while

the bottom holds the step return idler

sprockets.

Steps:The steps themselvesare solid, onepiece, cast in aluminumor steel.The stepsare linked by a continuousmetalchain that forms a closed loop.Each step in the escalator has two sets of

wheels, which roll along two separate tracks.The wheels are connected to the rotating chains,

and so are pulled by the drive gear at the top of

the escalator.

Floor plate:$t provides a place for thepassengers to stand before they step onto the

moving stairs. This plate is flush with the finished

floor and is either hinged or removable to allow

easy access to the machinery below.

Truss:The truss is a hollow metalstructure that bridges the lower and upper

landings.$t is composed of two side sections %oined

together with cross braces across thebottom and %ust below the top.The ends of the truss are attached to the

top and bottom landing platforms via steel

or concrete supports.

Handrail:The handrail provides aconvenient handhold for passengers while

they are riding the escalator.$n an escalator, the handrail is pulled along

its track by a chain that is connected to the

main drive gear by a series of pulleys.

The main drive machine is located in the upper pit area.The motor may be directly connected to the gearbo# or it may

transfer power through a belt drive.

The step motion is achieved by a direct step assembly connection

to the step chains.

Two-step chains$ one for each side of the

escalator are directly coupled to the ain

%rive a#le, the bull gear shaft, through the

step chain sprockets.

The step chain form a loop for the length

of the truss, from the step chain sprockets

at the upper end down to the tension

carriage gear or turnaround &depending onthe manufacturer' at the lower end or the

lower reversing station.
