The utility model discloses a light vehicle loading and unloading device which is used for loading or unloading light vehicles on a transport vehicle. The light vehicle loading and unloading device is formed by connecting two gangway foot plates and a plurality of connection pulling rods. The gangway foot plates are connected to form an integrated framework through two longitudinal beams and a plurality of horizontal beams. One face, in contact with a vehicle tire, of each horizontal beam is provided with a bent portion which is integrated with the horizontal beam and used for increasing the contact area with the tire. The side faces of opposite longitudinal beams of the two gangway foot plates are detachably connected through the connection pulling rods. The two longitudinal beams are provided with a plurality of sets of idler wheels, and each gangway foot plate is provided with transport holes. All gangway foot plates are detachably connected and located with the transport vehicle. The horizontal beams are provided with a plurality of process holes lowering the weights of the horizontal beams. The device can be used as a channel for the light vehicles to be loaded on or unloaded from the transport vehicle, so that the light vehicles can be more conveniently and more reliably loaded or unloaded, and the loading time is saved. The integrated framework structure is used, the weight is low, and two persons can easily finish unfolding and folding of the gangway foot plates through cooperation.
