Lift has a very long history


    Hand Pallet Truck use of lifting gear transport of goods, persons very long history. As early as 2600 BC, the Egyptians built the pyramids on the use of the most primitive lifting system, the basic principles of the system has remained unchanged: that a counterweight is declining, the load platform rise. Early lifting tools essential to human-powered. 1203, the French coast a monastery with the installation of a donkey-powered crane, this ends up with the history of human transporting heavy loads.

   British scientists Watt invented the steam engine, the crane began to use steam-powered device. Followed by William Thomson developed a hydraulically actuated access ladder, hydraulic medium is water. On the basis of these lifts, generation after generation innovative engineers are constantly improving lift technology. However, a critical security issue has not been resolved, that is, once the lift (hydraulic lifts) pulled up the rope ladder break occurs, the load platform will certainly crash occurred.

   Mr. Otis invented completely rewritten the history of human use of lifting gear. Since then, an elevator ride is no longer a "brave game", and a lift in the world are widely used. - Lift

   United States is both a major producer of construction elevators, is the world's largest elevator industry markets. However, Japan, Germany lifts rapid industrial development and the rise of RT and AT products, American manufacturers have in the 20th century, 60 to 70 years the world market occupies a dominant position is gradually eroded to form the United States, Japan and Germany, the three pillars of . In recent years, the U.S. economic recovery, the market is active, foreign manufacturers have to compete.

   From the 1970s, Japan became the largest producer of construction elevators, product quality and quantity improved quickly, have been exported to European and American markets, the annual output ranks first in the world. Since 1992, due to the appreciation of the yen, the domestic infrastructure investment fell and the Asian financial crisis, the annual decline. Current annual demand for the Japanese market around 3000.

   Europe is a huge potential market, European industrial countries both engineering lifts exporter, is also an important importer. Germany is the largest European market, followed by the UK, France, Italy and other countries. - Lift
