Title:
RETROFIT SYSTEM AND METHOD FOR MAINTAINING MINIMUM APPROACH DISTANCE
Document Type and Number:
WIPO Patent Application WO/2023/215835
Kind Code:
A3
Abstract:
A system for visually maintaining a predetermined minimum approach distance between load handling equipment and energized electrical equipment includes at least two elongate electrically insulating members that have lengths that correspond to the predetermined minimum approach distance that are mounted to at least a distal end of the load handling equipment so that they extend orthogonally outwardly from the distal end by substantially the predetermined minimum approach distance. One of the insulating members is rotatably mounted using a counterweight so as to be vertical, independent of the orientation of the load handling equipment. In use, when the distal end is in the vicinity of the energized electrical equipment, the insulating members provide visual indication that the predetermined minimum approach is being maintained and is not being encroached. A corresponding method is also described.
