Abstract
An improved load cell for logging trucks or similar vehicles. The load cell is principally formed by a single cast or machines resilient beam including a relatively flat central portion connected to a pair of end portions through respective relatively thin intervening portions. The end portions space the central portion from a support plate from which the end portions are welded. The support plate is bolted to a frame of a tractor or trailer, and a bunk-supporting cross-beam, which was previously mounted on the frame, is secured to the central portion of the beam by bolts which tap directly into the central portion. Strain gauges are secured to the undersides of the midsections to measure the load induced deflection of the beam. A transverse slot is formed in the support plate adjacent the inner edges of the end portions to allow the inner edges to be welded to the support plate.
