A converter gear dolly used in a combination of vehicles may have one or more axles and must be equipped with safety chains or cables to be secured to the vehicle pulling the dolly. The combination of any safety chains or cables used must be strong enough to prevent the dolly and any cargo units attached to the dolly from separating from the vehicle which is pulling it if the hitch on the dolly fails.
