The disclosure relates to a traction device and a traction method. The traction device includes: a support chassis; a swing arm, one end of the swing arm is rotatably connected to the support chassis by a rotating shaft such that the swing arm can be switched in a retracted state and a deployed state, wherein the swing arm in the deployed state is adapted to drive the wheel of the vehicle to rotate and tow the vehicle; a driving mechanism, connected to the swing arm, wherein the driving mechanism is capable of driving the swing arm to horizontally rotate around the rotating shaft to switch the swing arm between the retracted state and the deployed state; and a rolling assembly, disposed on a side of the support chassis and being capable of preventing the wheel from contacting with the side of the support chassis when the vehicle is towed.

A tractor, including a frame, a power wheel and a connecting assembly. The power wheel is rotatably arranged on a bottom of the frame. The connecting assembly is arranged on the frame and is configured to be attached to a goods carrier. The power wheel is rotatable relative to the frame to drive the frame to move, so as to drive the goods carrier to move synchronously through the connecting assembly. The connecting assembly is configured to move back and forth along a first direction relative to the frame to render a relative position between the goods carrier and the frame adjustable along the first direction. The first direction is a travelling direction of the tractor.

A parking robot for a transportation vehicle having at least two wheel axles and a method for operating a parking robot. The parking robot includes a main robot part and a secondary robot part which each have a pair of wheel support arms on two opposite sides. The two-part parking robot then moves under the transportation vehicle with respective folded-in wheel support arms and disconnects the secondary robot part from the main robot part to position the main robot part and the secondary robot part each in a region of one of the wheel axles beneath the transportation vehicle and to lift up respective wheels of the respective wheel axle of the transportation vehicle by folding out the respective pairs of wheel support arms.

A cluster transfer robot includes a body, two clamping arms arranged at the bottom of the body, and a first driving mechanism arranged at the bottom of the body. The first driving mechanism includes a driving wheel configured for driving the transfer robot to move. The clamping arm includes a second driving mechanism and a rotating assembly connected to the second driving mechanism, the rotating assembly includes a rotating arm rotatably connected to the body and a supporting wheel arranged on the rotating arm for supporting the transfer robot, the rotating arm is provided with a clamping portion for clamping automobile tire, and two clamping portions of two rotating arms are arranged facing to each other to define a clamping space for the automobile tire when the two clamping portions are close to each other. The cluster transfer robot can greatly reduce the construction cost of intelligent parking lots.

The present invention is a personal watercraft lift and transporting cart. In particular, the present invention is directed to a lift that can lift and rotate a personal watercraft (“PWC”) so that repairs can be conducted more ergonomically. The lift preferably has two lifting arms attached to upright frame members. In turn, the upright frame members extend vertically from a mounting base. The lift also preferably has two actuators pivotally attached to the lifting arms at one end and attached to the mounting base at the other end. When the actuators extend, the lifting arms lift and rotate. The transporting cart preferably has a cart chassis, a hull bunk and two receivers, where the first and second receiver are spaced to allow insertion of the first and second lifting arms so that the cart can be lifted and rotated by the lift with PWC mounted on the cart.
