Abstract

1299907 Signalling overloads in cranes LITTON INDUSTRIES Inc 8 Oct 1970 [8 Oct 1969] 48005/70 Heading G4H [Also in Division B8] A mobile jib crane is provided with a safety device which gives warning of excessive load for the particular operating conditions. The operator sets a switch 50 to indicate boom length and a switch 52 to indicate either tyres or outriggers support. Sensors 36, 44, 54 respectively produce signals representing the slowing angle quadrant, the boom angle and the boom load. A computer 42 comprises a memory unit 76, with an information input circuit 84, which provides a signal representing the maximum allowable load for the particular combination of crane parameters set and sensed. This is compared with the boom load signal from the sensor 54 and at 85% of the allowable load an alarm 72 is actuated. An alarm 74 is actuated at the maximum allowable load.
