APPAREIL INDICATEUR DE CHARGES

A load indicator is connected between a load line and a load handling member such as a hook. The indicator includes a hollow cylindrical housing, a plunger assembly including a transverse head slidably mounted in the housing, a pilot rod integral with the head and extending to a location outside the housing, means connecting a first end of the housing opposite the plunger rod and means connecting the plunger rod to the load line and to the load handling member, and a compression spring in the housing urging the plunger head toward the first end of the housing. The wall of the housing has several sight openings therethrough. A sight band of contrasting color is fixed to move with the plunger assembly inside the housing and to be visible through the sight openings. The spring is of strength to allow sufficient movement of the sight band so that a first color fills all of the sight openings when the load tensioning the load line, the indicator, and the load handling member reaches a predetermined rated value, and so that progressively less of the first color can be viewed through the sight openings as the tensioning load is reduced and the plunger head moves toward the first end of the housing.
