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 quite. They are one of the best elevators for durability, larger weight capacities and serving higher number of floors. 

The system operates with hydraulic pump connected to a cylinder that will raise and lower the elevator cab. The elevator will lift under pressure of the hydraulic fluid pumped into the cylinder when a call button is pressed from a higher floor. 

To travel in the downward direction, the controller will open a valve 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, it is also what makes them efficient in the use of power. They can even be lowered by batter backup in the event of power failure with automatic operation.
