As shown in fig. 1, 2 and 4, an embodiment of the present application provides a carrier, which includes a bottom frame 10, a comb rack 20, two sets of track structures 30 and a driving structure 40, wherein the comb rack 20, the two sets of track structures 30 and the driving structure 40 are all disposed on the bottom frame 10.

The rack 20 is installed on the bottom chassis 10 in a liftable manner, and the rack 20 is used for placing a vehicle. When the vehicle is taken out, the comb-tooth frame 20 can be lifted, so that the vehicle can be transferred to the comb-tooth frame 20 on the vehicle carrying platform or the parking berth.

Two sets of track structures 30 are respectively mounted on opposite outer sides of the base frame 10 in the width direction. The forward direction of the bottom frame 10 is the forward direction of the carrier during traveling, specifically the left-right direction in fig. 4, and the width direction of the bottom frame 10 is the direction perpendicular to the forward direction, specifically the front-back direction in fig. 4.
