Heightwatch 6

-height monitor/limiter

Heightwatch 6 is a stand-alone height monitoring safety system designed to limit the maximum angle, and therefore the height, of a single fixed length boom

Heightwatch 6 is an easy to use entry level height monitoring system that can be used on a variety of construction plant.
