摘要

This invention relates to a monitoring apparatus and to a support means comprising at least some of the components of the monitoring apparatus. The monitoring apparatus comprising at least an attachment member configured to facilitate the monitoring apparatus being attachable to, or in contact with, a support means; an electrical strain gauge to measure stress or strain experienced by the support means; and indicator means to indicate at least unsafe strain associated with the support means measured by the strain gauge. The apparatus also conveniently comprises a processor to control at least the indicator means in response to receiving electrical signals measured by the electrical strain gauge.
