Abstract: In order to obtain the energy consumption and efficiency data of simple lifts, energy transfer was studied under different working conditions. Comparative testing scheme of energy efficiency was established according to the actual situation. Among energy supply, effective nominal value and the nominal value of energy efficiency, the nominal value of energy efficiency was shose as the index to evaluate the simple lift energy consumption level. Threephase power quality analyzer was adopted to test the energy efficiency of two different type simple lifts with same parameters. The measured values of energy supply, available energy, energy efficiency and active power were comparative analyzed with the theoretical values under different working conditions. Finally, test results and analysis show that since there is an energy feedback loop during the falling process for the forced type simple lift, the overall traction type simple lift is more energysaving. Also, the test results provide the foundation for energy consumption of simple lifts.
