US Patent 7784589 Elevator lift cage load measuring assembly

Load measuring equipment has a small-area load sensor arranged between a support and a first damping body for vibration damping of parts relative to the support. The support may be a bracket and the parts may be a lift drive engine. The force on the sensor, which may be the force emanating from an engine foot of the drive engine made up of cage weight, cage load, weight of the counterweight, weight of the support cables and weight of the drive unit, is a small portion of the force on the support, such as the bracket. The ratio of the area of the first damping body to the load sensor determines the ratio of the force acting on the damping body to the force acting on L, and sensed by Z the load sensor.
