ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, en las operaciones de elevación de cargas, es muy importante que se mantenga la verticalidad del eje de elevación de la misma para evitar que se produzcan desajustes en el equilibrio y, como consecuencia de ello, accidentes indeseables.

As is known, in load lifting operations, it is very important that the verticality of the lifting axis be maintained to prevent imbalances in balance and, as a consequence, undesirable accidents. However, in many cases the crane operator, due to different circumstances, whether due to the type of load, position or type of machine, cannot see or control the simple view that said verticality is fulfilled.
El objetivo de la presente invención es, pues, proporcionar un medio para evitar dicha problemática y hacer que el operador, aunque no lo pueda ver, sepa en todo momento si la elevación se está produciendo correctamente o no. The objective of the present invention is, therefore, to provide a means to avoid said problem and to make the operator, although he cannot see it, know at all times whether the elevation is taking place correctly or not.
