The earliest appearance of similar lifts should be traced back to the ancient Chinese and European countries, where people and goods were transported vertically with tools such as Windlass. Modern lifts are the product of the invention of the 19th century steam engine. The first hydraulic lift was born in 1845, when the liquid used was water. In 1853, the American Eliza Ol "Elisha Otis" invented automatic safety devices, greatly improving the safety of cable traction lifts. A passenger lift with an Otis safety device was installed at a five-storey shop in New York, USA on March 23, 1857. Since then, the use of elevators has been widely accepted and developed at a high speed. The original lifts were propelled by a steam engine, so the buildings to be housed must be equipped with boiler houses. 1880, the German Siemens invented the use of electric lifts, from the veritable "lift" officially appeared.
Since then, the use of elevators has been widely accepted and developed at a high speed. In modern times we used to lift the cargo is a wooden ladder, it is inconvenient to use, climbing is more dangerous. The first city to install lifts in China is Shanghai. In 1907, the six-storey hotel was installed with two Otis lifts. Taiwan's first commercial lift was installed in 1932 in the Japanese era, located in Taipei City "Chrysanthemum Yuan department store", then called the cage. At present, the domestic production of lifts, product models are different, lifting height of 4 meters, 6 meters 18 meters or even up to hundred meters range. Select domestic and foreign advanced hydraulic, motor, pumping station system, hydraulic system explosion-proof device and hydraulic self-locking device. With novel design, reasonable structure, lifting balance, simple operation, easy maintenance and other products irreplaceable advantages. Widely used in plant maintenance, industrial installation, equipment maintenance property management, warehouses, aviation, airports, ports, stations, machinery, chemicals, medicine, electronics, electricity and other high-altitude equipment installation and maintenance.
