Hydraulic Elevator VS Traction Elevator

Nowadays, there are two kinds of lifts in the market: one is hydraulic lift and the other is traction lift.

Hydraulic lift has lower requirements for the shaft, such as the height of the top floor, the top floor machine room, and energy saving, etc. Traction elevator is the most conventional one. Traction lift is the most conventional, he is through the winch driven steel cable lifting, relatively speaking, the requirements of the shaft is relatively high, the height of the top floor is usually 4.5 metres, as long as the hydraulic 3.3 metres, in addition to the steel cable every 2 years depending on the situation needs to be replaced. The safety of both types of lifts are very high, there are national manufacturing standards. Hydraulic elevators are not afraid of height and traction elevators are not afraid of height.

Nowadays, hydraulic lifts account for less than 10%, or even smaller. The general lift is traction lift (that is, by traction machine and wire rope friction driven.) Traction lift is divided into machine room and no machine room. (Of course, can also be divided into passenger elevators, freight elevators and miscellaneous ladders, etc.) Now the lift technology has been very mature, relative to foreign countries than the domestic to be much more advanced. Nowadays, the traction machine is slowly developing to gearless, and the operation is more and more reliable and smooth. Power to points, generally can be regarded as three kinds. Hydraulic, traction, and forced (that is, the reel and so on to do the power, slowly being eliminated). Hydraulic lifts are suitable for low floors and large loads. Compared with traction lift, the development space is not big.
