Patent ID: 8584800

Claim:
A load monitoring system for a work platform, said system comprising: an operator platform, a base, a lift configured to lift the operator platform relative to the base, a load cell for monitoring the load on the operator platform, a central processor unit (CPU) receiving signals from the load cell and from one or more sensors that sense movement of the operator platform, said sensors being selected from the group consisting of a sensor that senses control signals that control operation of the lift or motion of the base, a sensor that senses actual operation of the lift or motion of the base, and an accelerometer that senses acceleration of the operator platform; said CPU predicting the dynamic load caused by movement of the operator platform based on input from said sensors and said signals from the load cell, comparing an actual load measured by the load cell with the predicted dynamic load, and providing an alarm and/or restrict operation of the work platform if a difference between the actual load and the predicted dynamic load exceeds a predetermined limit.
