Abstract
A weighing scale having a shock-absorbing platform support. The scale comprises a scale platform seated on a platform saddle, a scale base, a load-cell transducer having first and second body portions separated from one another, and a platform shock-mount. The platform shock-mount includes a Y-shaped transducer-support frame formed with three arms each having an extremity extended from a central frame junction with the scale platform saddle being fixed to the first transducer body portion and the second transducer body portion being fixed to the central frame junction, a preloaded spring assembly carried on the base and having a spring resiliently supporting each arm extremity of the Y-frame on the base, and a set of adjustable platform motion-limit stop screws. The preload force of the spring assembly and the platform motion permitted before the engagement of the limit stop screws are both adjusted in accordance with a specified platform-weight-shift test, so that as a shock force grows to exceed the readout weight limit of the scale the force is momentarily absorbed by the spring assembly before the platform is braked by the stop screws.
