Monitoring critical elevators in the automotive industry
Low-speed elevators with short process cycles are particularly challenging targets for condition monitoring. HD technology provides reliable early warning of deteriorating mechanical condition in this critical and very common application.
The need for condition monitoring of automotive elevators is as obvious as it is challenging. Low rotational speed and short process cycles make reliable results difficult to achieve. HD condition monitoring technologies are a proven solution to maximize elevator availability.
The availability of the elevators, moving car parts between floors, is crucial, and the economic impact of a breakdown is so significant that the payback of an installed measuring unit may be as little as a few hours.
The process cycles of elevators are periodic and exceptionally short, as they move their load up or down in a discontinuous and repetitive process typically lasting ten seconds or less. The patented HD condition monitoring technologies are specifically designed to deal with these difficult measuring conditions, while also providing extremely long prewarning times. This, in turn, enables fully utilizing asset life, cutting repair costs, and minimizing the consequences of unplanned downtime.
The SPM solution
Installation is straightforward. In the upper part of the elevator, DuoTech accelerometers are installed on the rollers. At the bottom of the elevator, DuoTech accelerometers are installed on each motor and gearbox, and on each of the shaft bearings. An RPM sensor is installed on the output of the gearbox.
Sensors with sealed connectors and cable protection conduits ensure a mechanically robust instal- lation. The signals from the DuoTech accelerometer are transferred to an Intellinova online system unit nearby.
