Agreed! Mechanical Engineer here. Why in the world take a chance? Any forces (bumps, truck turns on curves) will be transferred through a much smaller load bearing area (leg to pin lower cabinet). Increasing the risk of localized failure. Better is the option of having the cabinet on a skid and the load equalized as evenly as possible. Don't laugh, but filling gaps, between the pin cabinet and pallet, with even cardboard is an acceptable method of balancing out the contact/load distribution area. Points of contact is the key here. With legs it equals 4 (legs lagged/braced to pallet). Legs off it equals linear feet of cabinet contact area with pallet and this is where filling gaps is vital. For the best transport, hopefully the carrier/rigger gap fills the pallet as well to the trailer bed. That would be ideal! If the pallet is allowed to flex to much with the cabinet strapped tight to it, then it could be worse than 4-leg shipping. The 4 leg option would flex better and give a parallelogram type energy absorbing benefit! This is a plus!
The only debate that can/should come after this post is that many common day carriers offer/use, "Cushion" type trailers. The type that are very capable of transporting delicate electronic equipment. Industrial robots(Nachi, Motoman, Fanuc, ABB, Kuka, etc) and their control cabinets are a good example. Should a carrier be transporting with these next generation cartage trailers there is a good chance that even a pin on legs could go cross country 3-4 times over without a problem. Why take the chance though?
My 2 cents lol. time for another beer! Is anybody going to Bump my post for me? I bump other folks but have yet to get a bump! C'Mon SHOW SOME LOVE!
Lol
