The earliest lifting equipment appeared in ancient China and Europe. It is a kind of tool similar to "roller" to transport people and goods vertically. In modern times, we used to lift cargo as a wooden ladder, which is very inconvenient to use and dangerous when climbing. In March 23, 1857, a five storey shop in New York, USA, installed the first passenger elevator using Otis safety device. The original lift is driven by a steam engine, so the building must be equipped with a boiler room. In 1880, the German SIEMENS invented the use of electric elevators. Since then, the use of lifts has been widely accepted and developed at a high speed. Domestic production.
Electric lift, the product model is different, the lifting height is 4 meters, 6 meters, 18 meters.
