In our chapters we will introduce a background on elevators with discussion the types of elevators in general, with talking about Hydraulic and Traction type in details, also we will submit advantage and disadvantages of each.
In general, Hydraulic Elevators are suitable for low-rise buildings (Up to 6 floors) whereas, the roped (Traction) elevators are best suited to higher buildings. Over the last forty years hydraulic elevators has been accepted worldwide.
As Machine-room-less (MRL) traction elevator system was introduced to replace the hydraulic elevator, strong competition for the low-rise marked started. Aggressive market strategies have been applied solely to grasp the market and decline popularity of the hydraulic elevator.
These efforts created MRL trend at the expense of safety. Purchasers however, should be informed about the merits and shortcomings of both elevator systems to ensure the most suitable and safe application of each type.
In this paper, mainly hydraulic and MRL traction elevators are discussed and compared in order to enlighten consumers.
