Now the market elevator two conventional: a hydraulic elevator; a traction elevator. Hydraulic elevator on the shaft requirements are relatively low, such as the top level, the top floor room, as well as energy saving and so on. Traction elevator is the most conventional, he is driven by the hoist to enhance the cable, relatively speaking on the shaft requirements are relatively high, the top level is usually 4.5 meters, 3.3 meters as long as the water, the other cable every two years as needed to be replaced. Both elevators are very safe and have national manufacturing standards. Hydraulic stairs afraid of high fear is not heavy, traction ladder afraid of fear of high. Now the hydraulic elevator occupies less than 10%, or even smaller. General elevators are traction elevator (that is, driven by traction machine and wire rope friction.) Traction elevator is divided into the machine room and the machine room. (Of course, can also be sub-passenger ladder, cargo ladder and debris ladder, etc.) Now the elevator technology is already very mature, relatively foreign than the domestic to a lot of advanced. Now the traction machine slowly to the gearless, more reliable operation , Is the power of the points, generally can be considered three kinds of hydraulic, traction type, there are mandatory (that is, the drum and the like to do the power, and slowly eliminated.) Hydraulic elevator for low Floor, heavy load occasions. Relative traction elevator, the development of space is not.
