Hydraulic Elevator is a type of elevator that is powered by a hydraulic piston, which moves the elevator cab up and down. This type of elevator is commonly used in low-rise buildings, typically with up to five floors, although they can be used in buildings up to eight floors. It is controlled by a pump, which is typically located in a separate machine room. They are also generally less expensive to install and maintain than other types of elevators, which makes them a popular choice for smaller buildings or those with lower traffic volumes. Hydraulic Elevator is a reliable and cost-effective option for low-rise buildings that do not require high-speed or high-capacity elevators.
