Abstract

1479511 Monitoring crane load electrically G E BROOME 6 June 1974 25243/74 Heading GIN [Also in Division B8] Strain gauges 28a, 28b, 30a, 30b are mounted on a core member 26 in a hinge pin 22 mounted between a pair of trunnions 24 to support the boom 8 of a crane. The gauges are said to monitor the horizontal component of the turning moment created by a load upon the boom, and are connected in a bridge circuit so that the bending moment is self-cancelling.
