In the following, we have compared each of the traction and hydraulic elevators based on various criteria to determine their differences. These criteria include the following:
✳️ Energy consumption
In general, hydraulic systems are efficient and desirable systems compared to traction models in terms of energy consumption. . These elevators consume less energy than traction systems. ✳️ Efficiency
Traction elevators have a balance weight that can help these systems to be more efficient. . While hydraulic models have much lower efficiency due to not having this feature.
✳️ building height
As we mentioned above, traction elevators are very suitable for tall and medium buildings. While hydraulic models can be installed and used in low-rise buildings. do While hydraulic elevators have a slower performance and are able to move users between building floors in more time. They can have. So that heavy loads can be moved with these systems. While the cabin capacity is lower in traction systems.
✳️ Movement without noise
Traction elevators produce a lot of noise when working, which may be annoying for some users. But hydraulic models do not make much noise when working and have a smooth movement. Also, hydraulic elevators do not experience shock or impact when starting and stopping. While traction systems vibrate and shake every time they start and stop. Installation is more difficult and installers need more time. But on the other hand, hydraulic elevators are simpler and easier to install due to their less complexity, and installers can install and operate the system in less time.
✳️ Cost
Generally, traction elevators have lower installation and commissioning costs than hydraulic models. But hydraulic elevators need to spend more money for initial installation and operation. Also, service and maintenance costs in traction elevators are higher than hydraulic elevators. While there is no need to spend high costs for the service and maintenance of hydraulic systems. They make and install and operate the drive system equipment in it. But the location of the engine room in hydraulic elevators is not very limited. Usually, the engine room in these elevators is built in the lowest part of the shaft. In this case, the service and repairs of the elevator are done easily and spend less time.
✳️ installation space
Hydraulic systems are not very limited in terms of installation space, and these systems can be installed and operated in the building with more freedom. But the traction models are limited in terms of space or installation location and need a suitable space with larger dimensions. ✳️ environmental cleanliness
Hydraulic elevators with oil or fluid hydraulics are working and there is a possibility that this oil or hydraulic fluid will leak due to some causes. In this case, oil leakage will cause pollution and dirtiness of the environment. But on the other hand, traction elevators do not have the problems of hydraulic models in terms of environmental cleanliness, and the place of installation of the elevator does not get dirty or polluted. ✳️ number of starts in elevators Hydraulically, the number of starters reaches a maximum of 90 starters. While traction models can have up to 180 starts.
✳️ Duration of evacuation of users
If the hydraulic elevators fail, the evacuation of passengers will not take more time. Because these systems have a manual valve in the hydraulic circuit for emergency landing. In this case, a person can open this manual valve and lower the elevator. But traction elevators are not like this, and in case of a breakdown or an accident, an expert must be there and lower the elevator so that the users can evacuate. >Hydraulic elevators usually have a 15-25% lower purchase price than traction models. Of course, it should be noted that the purchase price of elevators is not a fixed figure and depends on various criteria.
