Hydraulic elevators are used in residential complexes, commercial buildings, office buildings, shopping malls etc. The hydraulic mechanism is also seen in stair lifts and wheelchair lifts. Hydraulic elevators are supported by a hydraulic cylinder that is driven by electric pumps. The service life for most
hydraulic elevators is 20 to 30 years, depending on the level of use and how well the elevator is maintained.

Maintenance and Repair of Hydraulic Elevators
It is very essential to take proper care and maintenance of hydraulic elevators. Hydraulic elevators have to be in proper function all the time so as to ensure safe passage. Therefore it is always necessary that hydraulic elevator manufacturers should also offer excellent and reliable and experienced engineers so that any problem in the elevator can be easily looked upon. There are many parts required in an elevator for its proper running like as rails, motors, cylinders, to gears and hydraulics. All parts need to be properly coordinated, and skilled technicians must provide excellent service so that the user reach his relevant destination safely.
Hydraulic elevators used for commercial purpose are different from those for home use. Commercial elevators may be with or without gears and they work with the help of a traction wheel on very heavy commercial grade steel cables , while, residential lifts are usually hydraulic driven. To keep all electronic parts functioning, the hydraulic elevator technicians must have a thorough knowledge of all elevator parts, and capable enough to provide elevator service for either commercial or home use elevators.
As a user, check the warranty to see what is covered before calling for repairs. All repair works must be performed by professionals who understand the function and technology of the lift so as to reduce down time. Safety and reliability is of the utmost importance to ensure optimum use for the life of the product. Service providers must be well trained, knowledgeable experienced engineers.
Common Defects
The most common defects found in hydraulic elevators are as follows:
- Cylinder damage
- Excessive creep
- Leaks
- Rough operation
Check the Maintenance Record
Always keep a track of the maintenance history. With time, the elevators will require more corrective maintenance. Check the maintenance log for the elevator to find out if maintenance requirements are more or less constant, or if they are increasing. A sharp increase in maintenance means that the elevator is approaching the end of its service life.
