One of the reasons for this is that elevator gearboxes used to be designed to include generous reserves, which provided they were regularly serviced, allowed them to achieve an extremely long service life.
As well as maximum safety and a high degree of availability, today’s lift user demands extreme stopping accuracy and low energy consumption, alongside low noise emissions.
Many of these requirements can be addressed and major improvements achieved simply by retrofitting a frequency inverter. Even if the original drive system is retained, this can offer a number of substantial advantages. Read more...
