<p>An apparatus for collecting energy in connection with a sheave system (1 -80) in a hoisting apparatus (1-20) provided with a sheave system. The apparatus comprises at least one generator (2-50) comprising a rotor (2-60) and at least one stator (2-80). The rotor (2-60) is connected rigidly to a sheave (2-21, 2-22) of the sheave system (1-80), and said at least one stator is connected rigidly to the sheave system such that when the load of the hoisting apparatus is rising or lowering, said at least one sheave (2-21, 2-22) rotates, whereby the rotor (2-60) rotates simultaneously but the stator (2-80) does not rotate, whereby electric energy is induced in the stator. The apparatus further comprises electric energy storage, means for modifying induced electric energy and storing it in energy storage; and means for supplying energy from the energy storage to at least one consumption device (295). The consumption device may be, for example, a working lamp, sensor, measuring device, communications device, signal device, charging plug or a combination of these mounted in connection with the sheave system.</p> |
