PURPOSE: To provide a new method adaptable to varying load conditions when operating an elevator or a hoist and an apparatus utilizing it. CONSTITUTION: This system is provided with a means for adapting the deceleration/stopage command to the varying momentary speeds of a cage 2 which are caused to change by the varying load conditions of the cage 2 itself. Also, a means is provided which verifies the deceleration/stoppage distance of the cage at certain known speeds, receives the average value of these distances and, directly or after further processing, compares this value with a range of known values. Outside of this range, reference data relating to the oblique curve for the deceleration/stoppage of the cage is automatically corrected in a proportional manner, the data being known to the electronic processor 28 which governs the operation of the system. |
