Our large mail and parcels processing equipment doesn't fit in any chamber either, and it doesn't have wheels. Just have to do it the old fashioned way and bring the portable equipment to the Cat. At least it can be driven to an open field for evaluation.
-Dave From: Ted Eckert [mailto:ted.eck...@microsoft.com] Sent: Tuesday, August 26, 2014 8:26 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] construction machinery in USA The FCC is generally not concerned with unintentional emissions from construction machinery. The general assumption is that a susceptible receiver would not be operating in close proximity to the construction equipment. It may no longer be a correct assumption, but that is the basis. It will likely be true in some cases. I can't imagine a Caterpillar 797 operating in a residential area. However, smaller pieces of machinery might be used closer to susceptible receivers. The rules have not kept up with technology and they are based on a time when the most significant ignition source in a vehicle was the distributor and when digital electronics did not exist in construction equipment. That being said, I'm not an expert in automotive EMC and I encourage anybody with better information to amend or correct what I have stated. (I would also like to know how you would run testing on a Caterpillar 797. I don't think it would fit in many chambers.)

For FCC, 47 CFR 15.103(a) says that digital devices utilized exclusively in transportation vehicle are exempted, but FCC OET says "The exemption is only intended for digital devices which operate primarily when the vehicle is operating in a mobile environment such as on a road or highway where the potential for interference is low" (KDB 892282) and I guessed that construction machinery would not covered by the exemption (i.e., may be covered by 47 CFR 15) even if the machinery can run on road. I also guessed that OSHA (or somebody else) may say something for electromagnetic immunity of such machinery as those malfunction can cause injury or death, but could find nothing about such requirements.
