<p>PURPOSE: A method for a load test of a hydraulic elevator is provided to perform a load test based on a criteria range required by elevator inspection criteria, thereby improving the reliability of a test. CONSTITUTION: A method for a load test of a hydraulic elevator is as follows. A first pressure value which is a pressure value when a car(50) is moved up and down in a non-loaded state is measured. A first current value is measured. A first speed value is measured. The first pressure value, the first current value, and the first speed are processed as data. A second pressure value which is the pressure value when the car is moved up and down in a loaded state is measured. A second current value is measured. A second speed value is measured. The second pressure value, the second current value, and the second speed are processed as data.</p> |
