ANORDNING FOR OVERVAKNING OCH BEGRENSNING AV ARBETSOMRADET FOR EN SKENBUNDEN TORNSVENGKRAN |
摘要 |
In a device for checking and limiting the working area of pivoting tower cranes guided by rails, the position of the crane being looked at is reproduced on a small scale by means of a driving system using a pin supporting a rotational driving system having a perpendicular shaft. The simulation of the position of the jib is reproduced on a small scale by means of a synchrogenerator 6, the baseplate 7 of which is rigidly connected to the shaft of the rotational driving system. <IMAGE> |
