The freight elevator needs to be reformed in the future

In order to prolong the service life of the freight elevator and ensure its safety and quality of operation, everyone will carry out a series of services such as protection, repair and transformation after the freight elevator is put into use. Freight elevator manufacturers want some freight elevators in Dongguan The freight elevator maintenance department claims that the freight elevators it manufactures will coexist in the building. We believe that to achieve this goal, it should be closely followed with the subsequent protection, repair and transformation services.

The transformation of the freight elevator in use is not carried out for no reason. It has its inevitable necessity. These are related to the years of use of the freight elevator in use, the aging of the components, the backward technology, and the function does not meet the needs. Factors such as freight elevator maintenance are closely related. Everyone knows that freight elevators are highly dangerous special equipment. Freight elevator manufacturers understand that in order to ensure the safe operation of freight elevators and protect the safety of people’s lives and properties, the country implements the license guidelines for the production of freight elevators. The management is implemented by the Quality and Skills Supervision Bureau to implement the safety inspection guidelines, that is, in addition to the inspection of the newly installed freight elevator, the annual safety inspection of the elevators in use is implemented once a year.

Throughout the history of China's freight elevator development, it can be seen that the development of freight elevator technology in China is very agile. Use fuzzy theory, serial communication skills and microcomputer control skills to replace the outdated relay control with contacts; use the leading variable frequency variable speed regulation to replace the backward AC-2 communication two-speed drive; use high-power permanent magnets Gear drive or planetary gear drive instead of low-power worm gear drive; use variable frequency speed control door machine to replace traditional old door machine; use non-slip photoelectric door protection device to replace traditional mechanical safety touch panel; use hollow auxiliary guide rail or Lightweight T-rails replace non-compliant angle steel auxiliary rails and so on. Scientific and technological progress has created outstanding external freight elevator maintenance conditions for the transformation of in-use elevators. Units that use these new skills and new components need to be engaged in the transformation shall carry out detailed and meticulous re-planning to achieve outstanding transformation effects.
