Load indicating device

摘要: A load-indicating device, e.g. an overload detector adapted to be placed between a load and hoisting cable of crane, consists annular member (I) high tensile steel, which is stressed by the along given axis - within its elastic limit provided with electric displacement transducer (III) portions at right angles vector (F, F'). The (1) elongated in proportion acting on it, whereby distance associated decreases, thus changing output from obtains input voltage source. This fed into circuit (IV) indicate actual weight and/or produce warning signal stop machinery dangerous overload.
