Abstract:
A weight measurement apparatus for a dump truck, the dump truck having a frame, a dump body movable relative to the frame and a hoist coupled between the frame and the dump body for moving the dump body relative to the frame, the hoist pin comprising:an elongated load bearing member of unitary construction having a first end and a second end opposite the first end, the load bearing member being coupleable to the frame of the dump truck at a first connection location proximate to the first end of the load bearing member and at a second connection location proximate to the second end of the load bearing member, the load bearing member being coupleable to one of the hoist or the dump body at a third connection location between the first and second connection locations, the load bearing member further having a first aperture extending completely through the load bearing member between the first and third connection locations and a second aperture extending completely through the load bearing member between the second and third connection locations, the first and second apertures each having a length, a diameter, and opposing ends, the diameter of each of the first and second apertures at a central location along its length being smaller than the diameter of the respective aperture at its opposing ends;a first load sensor attached to a wall of the first aperture near the central location to measure a first portion of a load borne by the load bearing member; anda second load sensor attached to a wall of the second aperture near the central location to measure a second portion of the load borne by the load bearing member.
