Abstract

The present invention concerns a system for measuring the vibration an operator of a piece of the equipment encounters while operating the equipment. The system includes at least one motion measuring means, such as an accelerometer. The accelerometer may be affixed to the equipment or integrated into the equipment. In addition, motion data recording equipment that is in electrical communication with the accelerometer may also be provided. An alarm may be used to indicate that a preset limit has been or is about to be exceeded.
