Hydraulic Elevators Hydraulic elevators are heavy-duty elevators built for frequent, long-term use. They also have an ultra-smooth ride quality and are typically very quiet. They are one of the best elevators for durability, larger weight capacities, and serving a higher number of floors. The system operates with a hydraulic pump connected to a cylinder that raises and lowers a piston to move the elevator cab. The elevator will lift under the pressure of the hydraulic fluid pumped into the cylinder when a call button is pressed from a higher floor. To travel in the down direction, the controller will open a valve in the hydraulic tank, slowly releasing this pressure after a lower floor call has been placed. Since this type of elevator can travel down by simply opening a control valve and pull from gravity, it is also what makes them efficient in the use of power. They can even be lowered by battery backup in the event of a power failure with automatic operation.
