An adjustable mounting bracket is supplied with the system, along with a reflective target. The reflective
target is mounted on the wall or other crane that is going to be protected by the collision avoidance
system.
The two laser distance set-points are adjustable to trip the relays from approximately 8 in. to 164 ft. (0.2-
50m). The first distance set-point (typically a Slowdown point) signals for the crane to start decelerating.
The second distance set-point (typically a Stop point) will signal the crane to apply its brakes.
The relationship between these points are as follows:
164 ft. (50m) ≥ Slowdown > Stop ≥ 8 in. (0.2m)
