Prior to the arrival of machine-room-less elevators, the height restrictions and sun shadow regulations, among other factors, meant that consideration had to be paid to the actual building, and hydraulic elevators were used when there were limitations, like not being able to load heavy equipment.
These elevators have a high capacity and are suitable for transporting heavy loads, thus, they currently operate in factories and warehouses. However, due to their structure they are almost always used in low-rise buildings.
