<p>The present invention relates to an improved safety device for elevator or lift maintenance and service. The safety device of the present invention can be used in any vertical transportation shaft to provide protection to individuals in the pit of an elevator. The safety device consists of a shoring means (1) which is connected to the vertical side surface (8) of the vertical transportation shaft via mounting means (18), which allow the shoring means (1) to be moved from a retracted position, wherein the shoring means (1) is disposed in the vicinity of the vertical side surface (8), to a deployed position, wherein the shoring means (1) is disposed vertically and spaced from the side vertical surface (8). In the deployed position, the shoring means (1) provides a physical barrier between the elevator car (11) and the floor (9) of the vertical transportation shaft, thus preventing potential injury to the serviceperson working in the pit.</p> |
