Abstract

1463811 Crane load indicating arrangement PYE Ltd 15 March 1974 [16 May 1973] 23233/73 Heading G1N A load indicating arrangement similar to that of Specification 1462785 is disclosed but the indication here is of total effective load defined as the weight at the hook of the actual load plus the total weight of a structure, acting through its centre of gravity, which supports the load i.e. in the latter respect, an equivalent weight at the hook which produces the same turning moment as the weight of the structure acting through its centre of gravity. The indication is derived by dividing the signal M which is proportional to the total turning moment of the boom about its pivot by the signal TR representing the load radius. Meter 58 is operative to indicate available lifting capacity or overload as the case may be in terms of total effective load at the hook.
