It is common sense that elevators require electricity to run. However, going beyond our expectations, this elevator can generate electricity while in operation. The carriage load and its counter weight blocks are often unbalanced during elevator operation. In the generation mode, the relative movements between the carriage and the counter weights enable the traction motor. With the use of high precise technologies, we can collect and reuse the electricity generated by the motor, this bringing about “elevator-generation”. The elevator here has precise energy feedback technologies. Compared with its traditional counterparts, this power-generating elevator can decrease consumption by over 30%.
