Regulator for crane slewing and lifting drive - has angle regulator and function generator for load straight line travel

摘要

The regulator is used for rotating or lifting drives of a crane used for ships. The load is moved from a picking up point to the depositing point along a specified curve, espec. along a straight line. The drives of the inner (4) and external (11) strut of the crane are provided with a rotating angle regulator. This arrangement specifies the rotating angle of the inner strut (4) relative to the reference line. The outward signal of the reference value transducer is used for adjusting the rotating angle gamma of the inner strut (4). The arrangement has function generator with input system for changing parameter value depending on the crane geometry.
