Abstract: 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.

Abstract: Method/apparatus for performing following acts on a system (2-2) that comprises an electrical motor (2-8) followed by a gear (2-16), and a speed output unit (2-10): monitoring a first set of frequencies from the system over a measurement period when the system is in a known good operating condition; storing the first set of monitored frequencies or derivatives thereof as reference data in a long-term storage system; monitoring a second set of frequencies from the system over a measurement period when the system is in an unknown operating condition; comparing the second set of monitored frequencies with the first set of monitored frequencies in a frequency domain; in the frequency domain, detecting changes between corresponding frequencies resulting from the second set of monitored frequencies and the first set of monitored frequencies.
