I know there must be a few OEs or other knowledgeable people on here that can answer
this for me. I looked on OSHA's site and searched here but could not find the answer.
This is for my own personal interest in crane operations. On the various jobs I have worked
years ago (retired now) I often asked myself the following questions but haven't found
the answers as yet.
My questions are:
For a crawler type lattice boom crane, under the new OSHA cranes rules
are they required to have a wind speed indicator mounted on the crane?
Which leads into a couple more questions.
1. If YES then do older cranes have to be backfitted with a wind speed indicator and is
there a requirement for its height, i.e., should it be mounted at the average working
height of the load or at the top of the boom or are multiple measurements at different
elevations required.
2. Can a locally mounted wind speed indicator that is calibrated and maintained
be used in place of a nonexistant or broken crane mounted indicator and if yes
then how close is close enough. Is a half mile away considered 'close' or not assuming
no large buildings or other structures that could influence wind direction or velocity
readings or have detrimental effects on the crane or its load are nearby.
All the hydraulic telescoping boom truck cranes I ever worked with had a wind speed
indicator. Not sure if they were required or the owner added them afterward or they
bought with the crane as an option. RT mobile cranes I don't remember having any
indicator for wind speed.
