1. A scale to measure a cantilevered load carried by lift members of a lift system, the scale comprising:
- a base coupleable to the lift system;
a lift member support system; and
a plurality of load cells coupled between the base and the lift member support system, each load cell comprising;
an elongated, vertically oriented structural member having an elongated, vertically oriented aperture extending through an entirety of a width thereof which defines at least one pair of offset strain gauge mounting surfaces that are parallel to a horizontal reference plane; and
an arrangement of strain gauges to sense deformations at least at one or more locations on the at least one pair of offset strain gauge mounting surfaces,wherein the elongated, vertically oriented structural member of each load cell further comprises a transverse base flange, the load cell being coupled to the base via the transverse base flange, andwherein the elongated, vertically oriented structural member of each load cell further comprises a vertically extending dove tail structure, the load cell being coupled to the lift member support system via the vertically extending dove tail structure.

Abstract
A waste bin scale to measure a cantilevered load carried by lift members of a lift system. The waste bin scale includes a base coupleable to the lift system, a lift member support system; and a plurality of load cells. Each load cell is coupled between the base and the lift member support system, and includes a structural member configured to deform during application of a load applied by the waste bin, where the deformation is indicative of the applied load. Other related waste bin scales, load cells therefor and methods of measuring waste bin scale loads are also provided.
