Abstract
1. Equipment, for the control of the braking initiation point in lifts, with markings (M1, M4), which are applied in the lift shaft (14) at a certain spacing from the storeys and which co-operate with a switch (15), which is actuable when the lift cage (6) travels past, and with a speed-measuring equipment (1) connected with the hoist motor (1), wherein the braking initiation point is determinable in dependence on the speed measured when the lift cage (6) travels past the marking (M1, M4) of the target storey and wherein stopping errors of earlier travels are taken into consideration in the determination of the braking initiation point, characterised thereby, - that a distance table (RAM1) is provided in the form of a store, in which the distances between the markings (M1, M4) of each storey are stored, - that a computer (RE) is provided, which from the distances forms a target travel (SSoll ) respectively associated only with the storey concerned and which determines a braking initiation travel (SEinl ) through subtraction of an empirical braking travel (SBr ) from the target travel (SSoll ), - that a travel counter (C3) is provided, which is started when the lift cage (6) travels past the first marking (M1) of a storey and on the signal change of the switch (15) brought about thereby, and - that a comparator (KO) is provided, which on equality of the travel counter state and the braking initiation travel (SEinl ) generates a signal determining the braking initiation point.
