Can the second-hand elevator join the elevator energy saving project?

There are many secondhand elevators on the market. These secondhand elevators may come from some old communities, or some buildings that have already been demolished. Because these elevators do not arrive at the stage of discarding, on the other hand, in the process of reusing, it may lead to a serious waste of resources. So some industry experts consider whether the used elevator can be added to the elevator energy saving project development.
In the face of such a question, it is the best to succeed in natural results, but it is difficult to achieve such a process. After all, in today's era, the process of elevator energy saving is in full swing, but we can't ignore a very real problem, which is about the cost of energy saving equipment. The high production cost is always one of the drawbacks of such industries can not overcome, one of the industry is also flawed. So in most cases, whether the used elevator can be used in the energy saving project is still an unknown number.
Although there is a certain expectation for the future, there are many energy losses on the used elevator itself, which not only need to be upgraded when it is used again, but also must meet all the indicators needed for elevator energy saving.
