A caster mounted weighing system comprised of at least three caster assemblies mounted to the bottom of a bed, container, or other surface suitable for weighing, a control unit, a junction box, and a means for transmitting signals to and from the caster assemblies, junction box, and control unit. The caster assembly may be comprised of a caster, which rests on the floor, a load cell attached to the caster, strain gauges or other means for measuring the load applied to the load cell, and a stem or other attachment means which permits the caster assembly to be mounted to the bottom of a bed frame, container, or other surface suitable for weighing. In alternate embodiments, each caster assembly may be comprised of a plurality of casters centered below a caster plate, or the caster assemblies may be secured to the bed or container by a collar or clamp, rather than by a stem. In an alternate embodiment, the system is comprised of support assemblies, rather than caster assemblies, mounted to the bottom of a bed, container, or other surface suitable for weighing, a control unit, a junction box, and a means for transmitting signals to and from the support assemblies, junction box, and control unit.
