Some problems with cargo cranes that occur on the ship.
Deck crane hoisting limit switches
While checking hoisting limit switches, due to incorrect setting of the hoisting limit switch on deck crane no. 1, noticed that the system differs from the ones on other sister ships. Hoisting up limit switch is no longer activated by means of a small weight that slacks the chain when the hook touches it, thus activating the micro switch, as on the previous sister ships; instead it has been put on the cam limit switch together with lowering limit. This means that the hoisting up limit is no longer fixed, to hook being about 2 meters below the boom head regardless to the boom angle; but that it is activated when the exact amount of wire rope is wound up on the drum.
