The Advance Metalworking Co., Inc. manufactures the Wing Jack elevating platform trailer. This 4,000-lb payload capacity trailer is specifically designed to carry aircraft wing jacks only. The Wing Jack trailer simplifies any loading situation due to its ability to hydraulically lower to ground height. When lowered, the built-in ramp provides a 3-degree load angle for easy, drive-on access. This single axle trailer comes equipped with pintle hitch and features a built-in tie-down rail as well as six standard “D” ring tie-downs. The trailer does not include lights, fenders or brakes and, therefore, is not intended for over the road use. Maximum speed recommended is 15 mph.
