Elevator past failures, the level of quality is not high, mainly reflected in the electrical control of the elevator. Twospeed elevators by the exchange control relay, the device more plex control structure, contact the contact reliability poor exchange for more early speed elevator control of discrete ponents, the SCR domestic electronic devices such as manufacturing quality is not stable。 DC Speed elevators are basically dragging generating units, discrete ponents together with elevator control and speed backward technology, the device ages, the elevator is the main reason for poor quality. Therefore, the lifts carry out technological transformation mainly on the escalator to carry out electrical parts. The mechanical lift some of the quality of relatively more stable, particularly the domestic production of several major Dianti Chang elevator, mechanical situation relatively well. The general conduct of the elevator, mechanical adjustments and the only part of overhaul. Only in the long term use of elevators, escalators or mechanical wear Machinery Manufacturing innate quality problems exist, to consider the relevant parts of the replacement. Elevator safety equipment, such as door locks, forced to close installations, many no longer conform to the requirements of GB7588 a l995, the transformation is a key target. Doorto improve the reliability of noise and work with the new system or doorVVVF such as the doorinstalled governor of the portal machine, the effect is also very good. Some occasions, the lift of not only the pursuit of lower failure rate, it will be on the elevator control methods (to signal control centralized control, a single run parallel to twoTaiwan), the lift speed mode (twospeed transfer to turnover, twospeed reform 10% VVVF, crosschanged VVVF) to be transformed. For the pursuit of the perfect lift, many hotels, schools, agencies, offices also called on the decoration of the lift. The development of technological transformation of 2 lifts. No. 144 documents in the promotion of the emergence of a number of elevators in the technological transformation of enterprises. Initially limited to solve the lift of oldfashioned relay control of the elevator in a high failure rate. Imports by the PLC PLC, according to the logic of elevator control relay, the preparation of features and functionality consistent with the original lift the software program, transforming the content is mainly to twospeed twospeed. After the PLC because of the elevators, control equipment greatly simplified, eliminating the root causes of many of the lift failure, failure rate dropped substantially, effective transformation is very clear, resulting in the lift of momentum of development is very Meng, universal soon. In addition to funds used in the elevator or escalator limited useful life can only be updated for too long, almost all of the lift for the purpose. With the lift of the accumulation of experience, technical transformation has taken the lift logic control simple copy of the initial stage, twospeed elevators will be transformed into the exchange speed elevators, will be further developed to exchange lift into the current
