"Energy feedback technology"is a brake in the elevator when the elevator traction machine as a generator used to produce electricity back to the building power system using energy saving technology.

This technique not only energy saving, but also realize the safety of the elevator, so that power outages and other unexpected situations arise when, still able to function properly. The "variable speed lift technology " is based on the product's energy saving potential of conventional elevators, can lift the maximum speed of up to 1.6 times the rated speed, passenger waiting time was reduced by about 12%.
