<p>#CMT# #/CMT# The device comprises an auxiliary lifting unit for the transport of reactor elements. An adapter with a load sensor (8,9) is provided. A spring (7) is provided, which is released by overloading an additional path for protection of the system. An amplifier (10,11) and a transmitter (14,15) are provided, in which transmitter passes on the load values to a receiver. The receiver on a crane control disconnects the drive of the rope drum during exceeding of a predetermined load value. #CMT#USE : #/CMT# Device for preventing overload of a crane, particularly a reactor building crane. #CMT#ADVANTAGE : #/CMT# The amplifier and a transmitter are provided, in which transmitter passes on the load values to a receiver, where the receiver on a crane control disconnects the drive of the rope drum during exceeding of a predetermined load value, and thus enables a simple and easy operation of the crane overload preventing device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of an adapter of a crane overload preventing device. 7 : Spring 8,9 : Load sensors 10,11 : Amplifiers 14,15 : Transmitters 16 : Housing interior.</p> |
