Abstract
Abstract An improved vehicle carrier having upper and lower levels for receiving a plurality of vehicles. The upper level of the carrier includes a rear table which can be tilted to provide a ramp for vehicles being loaded onto the upper level. Each rear table is lifted up and down by a pair of telescoping struts disposed on either side of the vehicle carrier. A rear pair of telescoping struts is directly attached to the rear table. Each one of the rear pair of telescoping struts is pivotably attached at a lower end to the chassis of the vehicle carrier and is pivotably attached at an upper end to the rear table. A forward pair of telescoping struts is rigidly mounted at a fixed angle to the chassis and has an upper end which is pivotably intermediately attached to a swing arm beam. A rear end of the swing arm beam is pivotably attached to a forward end of the rear table. A forward end of the swing arm beam is adapted with a slot to pivot and translate about a fixed pivot point on the chassis of the vehicle carrier. In extending the fixed angle telescoping strut, the lifting end, or rear end, of the swing arm beam is lifted directly vertically, so that the rear table is raised vertically without any horizontal component of movement.
