(54) Electric hoist with an improved functionality


(57) An electric hoist (25) having an improved functionality, comprising a transmitting apparatus, situated inside a driving device (23), and a receiving apparatus, inserted inside a casing (26) in a position adjacent to the electric driving motor (10) of the hoist (25). By pressing at least one push-button (24) of the driving device, the transmitting apparatus is capable of sending codified signals (S), via radio, to the receiving apparatus for the remote up and down moving of the load (14) hung on the hook (22) of the hoist (25). Furthermore, as this is an electric hoist (25) of a machine with moving organs, the transmission of coded signals (S) avoids any undesired setting in motion of the machine, as the receiving apparatus is only activated after recognizing the signal (S) transmitted by the transmitting apparatus.
