Abstracts: The proliferation of science and technology has reduced human efforts in every field. Many of the human activities now rely on technological innovations. The past two centuries have seen a phenomenal improvement in various inventions and discoveries. Same is the case with the first elevator which finds mention in ancient texts to its development in last two centuries. The first commercial passenger elevator was installed by the Otis Elevator Company in 1857 in New York City. It climbed at a then-staggering rate of 40 feet per minute. Today, an Otis elevator in the Burj Khalifa tower in Dubai soars up at a speed of 22 mph. And it didn't even top a new ranking of the fastest elevators in the world from Emporis, a database of construction projects. The list is dominated by elevators located in Asia, including China, Taiwan, and Japan. Japan’s Hitachi said Monday it will provide the world’s fastest elevators, which can clock speeds of up to 72 kilometres (45 miles) per hour, to a high rise building in China. The lift is also used to move other things from one elevation to other. The elevator concerned in our project is a one which runs on solar power. It is used for just elevation for a single level. In this project, we are going to do design a hydraulic safety system for the specified elevator so that it moves the lift to the ground floor in case of power failure of breakage of rope while making sure that it does not require any power
