Abstract
A machine has a movable boom for lifting a load, and an overload sensing device mounted on the boom to sense boom deflection. The overload sensing device includes a rigid beam having one end secured to a vertical side plate of the boom only by anchors spaced widely apart, welded preferably on opposite sides of the centroid or neutral axis of the boom side plate. The beam has a free end, on which an adjustable contact plate is carried, to engage a switch adjustably carried on a mounting plate secured to the beam side plate.
