Lift functionality testing method, involves measuring maximum pressure in hydraulic pump and determining maximum weight corresponding to maximum pressure from line, which runs through two measured pressures and weight

摘要

The method involves setting a car on a force measuring equipment and measuring weight (F1) exerted by the car on the force measuring equipment. A pressure (P1) corresponding to the weight is measured. The car is lifted from the equipment and moved upto a preset holding point, and another pressure is measured. A connection between a hydraulic pump and a working piston is broken and a maximum pressure (P3) in the pump is measured. A maximum weight (F2) corresponding to the maximum pressure is determined from a line, which runs through the measured pressures and the weight.
