The paper deals with the principal aspects of the testing of geared elevator machines in laboratory conditions. A brief description and illustration of the testing equipment is included as well as a summary of the quantities measured during the tests. The machine load capacity was determined in respect of the temperatures of several reference places. The graphs were plotted from the measured values and compared with the theoretical exponential temperature/time diagrams. The measurements were taking while the machine worked in various conditions (variable braking torque and operation mode). The overall efficiency of elevator machine has also been determined.
