Small machinery elevators will completely replace general elevators

Chinese machine room elevators are the products of the 1970s, when they are controlled by relay, that’s why they need big machine room. However, with the large application of the computer technology of the 21 century, big machine room elevators have cost developers and elevator users huge cost risks and some foreign corporations never input new technology to China and update Chinese machine room elevator technology to avoid Chinese elevator industry having strong competition in the world.

As many Chinese elevator corporations lack the study of the world elevator technology and the recognition of exploiting the elevator technology, they are always enslaved to foreign corporations at a large extent and over trust in the impact of that Japanese technology such as Mitsubishi and so on. Moreover, some manage institutions in elevator industry are also lack of the policy of changing and improving the industry, which causes stasis of the elevator industry for many years.

Each year, almost 100 thousand elevators are used now, and especially the national 40 thousand residential elevators of the developers, which have changed big machine rooms into small ones, have saved the building cost by 600 million. Moreover, if the source matching and all other factors are added, the total contribution of the application of small machine room elevators to the country economy is at least 1.5 billion. In future, small machine room elevators will certainly replace big machine room elevators for the developing cost, designing convenience, reasonable building structure and residential structure, energy sources and other aspects.

Actually, there is no problem of the application of small machine room elevators in China, although some brand elevators have not promoted the small machine room elevators and have high prices. In fact, the cost of VVVF small machine room elevators has no difference with general machine room elevators especially those speed under 1.75M/S elevators, their cost are totally the same. The reason of high cost of those speed over 1.75M/S elevators is for the collocation of the host not for the increasing equipment cost.

At present, some no machine room elevator manufacturing corporations have provided many kinds of small machine room elevators. Low equipment price of VVVF small machine room elevators are mainly provided by WALESS elevators, who formally introduced a VVVF small machine elevator whose price is the same with big machine room elevators to national users in Jan., 2005. This product introduced the latest small machine room elevator technology from Italy. Its host is also the latest-small but completely satisfy the usage of small machine room elevators. Small machine room elevators with non-gear host provided by Kone are also good.

We suggest that developers choose VVVF small machine room elevators rather than big machine room to save cost when choosing residential elevators.

In 2010, Chinese general traditional big machine room elevators will certainly replaced by small machine room elevators and no machine room elevators as the two-way security system replaced the traditional one-way security system in Jan.1, 2005. The technology of small machine room elevators can completely refer to the present national elevator standards.

 The reform of the elevator industry is just on the way, so elevator corporations and elevator users should notice the movements all the time and produce and choose the products that satisfy the need of future development.
