OOSC, Part II, Item 2. Cargo Securement, a. General Securement - Mobile Home

Nebraska had a modular home that was in transport tip over/become unsecured from the trailer during a cornering maneuver. The house was secured to the trailer with lag screws, and the company indicates this is standard operation for house movers. We can only find anecdotal evidence of the strength of lag screws driven into wood beams, and it is all over the board, from 250# to 800+# per lag screw.

The house moving industry indicates that lag screws through eyelets on a trailer is the standard method of securement. There is a lack of a documented, standardized, securement technique for this commodity. Additionally, there is a lack of data on the working load limit of lag screws in wooden boards is to make a determination if a modular house is properly secured prior to movement. Lack of guidance on this subject makes congruent North American enforcement impossible.

Nebraska asks for CVSA/FMCSA/CCMTA to coordinate with the house/building mover industry to determine what methods of attachment provide sufficient securement to adequately prevent a house from becoming detached from the trailer during normal driving, to include starting, stopping, cornering, traversing normal grade changes, and exigent evasive driving that is encountered during movement of this type of commodity.
