Description
In hydraulic elevators, the elevator load is carried by the building foundation.
The machine room can easily be located on the ground or first floor. During installation, the risk of accidents is lower due to the safe use of the machine room.
Rescue operations can normally be performed by informed building occupants within a few minutes, with no need for specialists. In emergencies, intervention can be carried out without entering the shaft or climbing to the top floor.
Installation and maintenance costs are lower. Spare part supply is easier.
Damage caused by earthquakes is less compared to rope-driven elevators. They do not have a counterweight that could pose a life-threatening risk during shaking.
Hydraulic elevator units require less service because they consist of fewer parts. The motor-pump drive system, usually immersed in oil, operates smoothly with minimal wear.
They are less sensitive to fire sprinklers and extinguishing systems located in the elevator shaft and machine room.
They are the elevator type that provides high lifting capacity in the safest way.
Hydraulic elevators can be used like machine-room-less elevators. Inside the building, they provide more effective flexibility in usable floor area. For example:
Hydraulic elevators use less shaft space compared to rope systems since they have no counterweight (approximately 0.5m² saved for a 630kg elevator).
Since hydraulic elevators do not impose vertical loads on the building, column sizes around the elevator shaft can be reduced.
In machine room solutions, they offer flexibility in selecting the room location.
Can easily be installed externally in buildings without a shaft, suitable for terrace elevator designs.
They are the most economical solution that can be installed in old buildings without requiring structural reinforcement.
If additional floors are added to the building, hydraulic elevators adapt well to this situation.
The limited amount of heat generated by the hydraulic power unit during downward movement helps to mitigate the low temperature at the building's base.
