Abstract
A system for adapting the deceleration/stoppage command to the varying momentary speeds of the cage which are due to varying load conditions of the cage itself. The system aso verifies the deceleration/stoppage distance of the cage at certain known speeds, determines the average value of these distances and which, directly or after further processing, compares, this value with a range of known values, outside of which reference data relating to the oblique curve for deceleration/stoppage of the cage is automatically corrected in a proportional manner, the data being known to the electronic processor which governs operation of the system.
