For a heavy machine with accessory equipment, what extra securement step is commonly required?
- A.Only the parking brake is needed
- B.Accessories may ride raised if chained loosely
- C.One chain over the top suffices
- D.Accessories such as booms or blades must be lowered and separately secured, and the machine itself restrained against movement in all directions, often with at least four tiedowns
Correct answer
D. Accessories such as booms or blades must be lowered and separately secured, and the machine itself restrained against movement in all directions, often with at least four tiedowns
Why
Special rules for vehicles and machinery recognize that wheels roll, tracks slide, and raised attachments swing and fall. Lowering attachments to the deck and restraining them removes stored energy that ordinary cargo rules were not written for.
