Load transfer mechanism for weigh in motion

A beam of a load transfer mechanism elongated along a depth axis of the load transfer mechanism, the beam comprising:

• a plate with a load-bearing surface;
• a tube portion including a base wall and a cover, the base wall and the cover including respective interior surfaces that define a cavity therebetween, the cavity elongated along the depth axis and configured to receive a sensing package therein that engages the respective interior surfaces of the cover and the base wall for measuring forces exerted on the load-bearing surface of the plate;
• and
• a neck extending between and joining the plate to the cover such that the neck transmits forces exerted on the load-bearing surface to the sensing package via the cover, the neck tapering from a wide end at the plate to a narrow end at the cover,
• wherein the beam extends a height from the load-bearing surface of the plate to a mounting surface of the base wall, wherein a midpoint of the height of the beam is vertically spaced apart from a midpoint of a height of the cavity between the respective interior surfaces of the cover and the base wall.

A beam of a load transfer mechanism elongated along a depth axis of the load transfer mechanism, the beam comprising:

• a plate with a load-bearing surface;
• a tube portion including a base wall, two upright members, and a ceiling member, the two upright members joined to different corresponding lateral edges of the base wall, the ceiling member connected to and extending between the two upright members to define a cavity, the cavity having an oblong cross-sectional shape such that a width of the cavity between the two upright members is greater than a height of the cavity between the ceiling member and the base wall, the cavity configured to receive a sensing package therein that engages respective interior surfaces of the ceiling member and the base wall for measuring forces exerted on the load-bearing surface of the plate, the tube portion having a substantially constant lateral external dimension extending along the two upright members and lateral edges to a mounting surface of the base wall that is opposite the plate load-bearing surface;
• and
• a neck extending between and joining the plate to the ceiling member such that the neck transmits forces exerted on the load-bearing surface to the sensing package via the ceiling member.
