Abstract
A configurable-width industrial weighing scale configured to hang directly from one of multiple engine-powered lifting machines and/or to couple to a quick-attach plate or other attachment means of an engine-powered lifting machine and configured to directly support a lifting element and/or couple to a quick-attach plate or other attachment means of a lifting element. A weighing element includes front and rear plates in parallel with one another and a weighing assembly therebetween. The weighing assembly may include a strain gauge-based load cell, a shock absorber, a mechanical preload adjustment to control a vertical difference between the front and rear plates, a mechanical linearity control to adjust an angle of the weighing assembly, a carriage alignment bolt to compensate for an uneven surface of a lifting carriage of the engine-powered lifting machine, and/or a mechanical adjustment to compensate for a distance between the front plate and a load.
