Abstract:
A device for controlling a motor-driven hoist;a housing; a power source, secured to the housing, for providing electric energy; a control unit supplied with electric energy from the power source and secured to the housing, said control unit having control elements operable from outside the housing between an inactive ready position and an active position for delivering control signals; a transmitter supplied with electric energy from the power source and receiving the control signals from the control unit for wireless transmission of the control signals to a receiver operatively connected to a power controller of a drive of a motor-driven hoist; and an activation switch so operatively connected to the power source that actuation of any one of the control elements establishes a supply of electric energy from the power source, whereas the supply of electric energy from the power source is cut, when all the control elements occupy their ready position.
