Escalators. An escalator is a moving staircase that carries people between floors of a building. Its use is widespread, and includes department stores, shopping malls, airports, transit systems and hotels. Most methods of transport cannot be used when they break down or lose power. However, a non-functioning escalator can still be used as a. With the help of pulley we can apply force at any direction for lifting load. 2. mechanical advantage of pulley : Mechanical advantage of pulley is calculated as the number of pulley used. If a pulley system includes two pulleys then it ma is 2. There are three types of pulley fixed pulley, moveable pulley and compound pulley The Cable System. The most popular elevator design is the roped elevator. In roped elevators, the car is raised and lowered by traction steel ropes rather than pushed from below. The ropes are attached to the elevator car, and looped around a sheave ( 3 ). A sheave is just a pulley with a grooves around the circumference
Escalators utilize pulley systems to function. In all of these examples, a cable system works in order to make lifting easier or to make moving items easier. Pulleys are essential to being able to move and lift very heavy or large items The present invention is an improved escalator handrail drive system. The system includes a drive wheel with an uphill and downhill side, an escalator handrail wrapped around a portion of the drive wheel, and two pressure rollers. One pressure roller is positioned adjacent to the downhill side of the drive wheel and forms a first nip therebetween and the other pressure roller is positioned. The working rule of Escalators in Pakistan is like the pulley system. A pulley system is utilized to draw the water from the well.
