The escalator system is simple. It is not nearly as good as an elevator at lifting people dozens of stories, but it can move people better in short distance. Once an elevator is filled up, you have to wait for it to reach the floor you’re in but in an escalator, no more waiting period! As soon as you load one person on, there’s space for another.
Escalators can be placed in the same physical space as one might install a staircase. People are guided toward main exits or special exhibits and they may be weatherproofed for outdoor use. The good thing is that a non-functioning escalator simply becomes a normal staircase, not like other conveyances which becomes useless when they break down.
Each and every part in an escalator is essential. Some parts are the gears, truss, steps, tracks, handrails, and escalator rollers.
There are what we call chain rollers and step rollers. The core of an escalator is a pair of chains, looped around two pairs of gears. The drive gears at the top are turned to rotate the chain loops using an electric motor. A typical escalator uses a 100 horsepower motor to rotate the gears. The motor and chain system are housed in a metal structure extending between two floors called truss.
Instead of moving a flat surface, as in a conveyer belt, the chain loops move a series of steps. This is why passengers easily get on and off the escalator.
At the top and bottom of the escalator, the two tracks converge so that the front and back wheels of the steps are almost in a straight line. This causes the stairs to lay in a flat sheet-like arrangement, one after another, so they can easily travel around the bend in the curved section of track. The tracks carry the steps down along the underside of the truss until they reach the bottom landing, where they pass through another curved section of track before exiting the bottom landing. At this point the tracks separate and the steps once again assume a stair case configuration. This cycle is repeated continually as the steps are pulled from bottom to top and back to the bottom again.
Alternating current motors that operate at constant speed are used in escalators so that they move at the rate of 1 to 2 feet per second. From the floor, the maximum angle of inclination is 30 degrees up to a maximum of 60 degrees. The aluminium or steel steps move in a continuous loop and handrails are a requirement so that those on the escalator can hold on when it is moving. A handrail is a rubber conveyer belt that is looped around a series of wheels. This belt is exactly configured so that it moves at exactly the same speed as the steps, to give riders some stability.
The other parts won’t function well without the step and chain rollers. It is important to choose the best escalator rollers for the escalator because the speed and other factors might be affected which can lead to danger.
