Abstract: An automatic underride protection actuator for a trailer, where the trailer has a forward end and an opposed rearward end and has a tiltable bed supported by a trailer frame, the tiltable bed being tiltable with respect to the trailer frame between a transport disposition and a load/unload disposition, the tiltable bed presenting a trailer rear margin, a rotatable ramp being operably coupled to the tiltable bed proximate the trailer rear margin, the automatic underride protection actuator including an actuation apparatus. The actuation apparatus is operably coupled to the trailer frame and to the rotatable ramp, the actuation apparatus acting to rotate the rotatable ramp between a ground engaging load/unload disposition when the tiltable bed is in the load/unload disposition and an underride protection disposition when the tiltable bed is in the transport disposition.
