fifth wheel. Trailer wheels may roll if they are not chocked. Failure
to comply may result in serious injury or death to personnel or
damage to equipment.
Fifth wheel, ramps, and trailer kingpin must be coated with grease. Failure
to comply may result in damage to equipment.

overrun fifth wheel. Failure to comply may result in damage to equipment.
