Abstract
A load monitoring system (14) is provided for a mobile work platform that includes an operator platform (6), a base (2) and a lift mechanism (5) for lifting the operator platform relative to the base. The load monitoring system includes a load cell (12) for monitoring the load on the operator platform (6) and a control device (16) for controlling operation of the work platform, wherein the control device (16) is constructed and arranged to sense and monitor both static and dynamic loads on the operator platform.

-10. (canceled)
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) connected to receive signals from the load cell and from one or more sensors,
- 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 attached to the operator platform;
- said CPU configured to
- predict the dynamic load on the operator platform based on input from said sensors and said signals from the load cell,
- compare an actual load measured by the load cell with the predicted dynamic load, and
- provide 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.
A method for monitoring a load system in a work platform comprising:
- sensing a load on an operating platform of the load system;
- sensing one or more of the following actions or signals:
- control signals that control operation of a lift or movement of a base,
- operation of the lift, and
- acceleration of the lift;
- predicting a dynamic load on the work platform based on the sensed load and the sensed actions or signals;
- comparing the sensed load with the predicted dynamic load;
- and
- providing an alarm and/or restricting operation of the work platform if a difference exceeds a predetermined limit
