5.5 Mounting Location for Wing Bracket on HSA Boom
1. Mounting the NORAC UC4 breakaway bracket to the HSA aluminum boom will require
the use of a RAU aluminum boom clamp.

2. Using this clamp will also require adjusting the width of the hole in the NORAC bracket to
accommodate the larger bolts and differences in dimensions between the 2 parts.
3. For best performance, the sensor should be mounted 1-2m in from the boom tip.
Depending on the size of the boom, this may require putting the sensor on the breakaway
bracket.
4. It may be necessary to create an adapter to mount the NORAC bracket to the RAU HSA
boom. This bracket, when used in conjunction with the RAU HSA boom clamp, will
prevent the boom from rotating down towards the ground due to the clamp slipping on the
aluminum.
