A tire-mounting structure, the tire-mounting structure having a laterally extending end wall, two protrusions longitudinally extending from the end wall, the two protrusions spaced apart from one another, and a recess formed between the two protrusions. The recess is dimensioned such that a first distance between the two protrusions at a distal location relative to the end wall is longer than a second distance between the two protrusions at a proximal location relative to the end wall, where the first distance corresponds to a first tire dimension and the second distance corresponds to a second tire dimension, the second tire dimension being narrower than the first tire dimension.

A compression wheel chock system is disclosed. The system is comprised of two, triangular-shaped devices having longitudinal channels and a lanyard. An object of the apparatus is to enhance wheel chocking by preventing a wheel from moving both fore and aft while chocked. During installation, the lanyard is fed through a channel in each chock and is drawn tight by the user. As the lanyard is tightened it compresses the chocks around the wheel while at the same time compressing the channels and securing the lanyard therein.

A wheel chock assembly to secure a wheel of a motorcycle and/or bicycle by encasing the wheel and secured by a lockable lock pin. The wheel chock assembly can be used with one of the various mounting assemblies and with the frame securement collar assembly. The wheel chock assembly when mounted on one of the various mounting assemblies can be used to secure a motorcycle and/or bicycle on the bed of a truck or on the bed wall of a truck, trailer floor, trailer wall or trailer railing and even in a garage on the floor or wall. The securement collar assembly is used either around the steering column and frame attaching to the wheel chock assembly's lock pin for securement or between the rear tire and the frame attaching to the wheel chock assembly's lock pin for securement.

The present invention relates to a movable station. More particularly, the present invention relates to a movable station including a vehicle, a multi-tier open frame rack installed in the vehicle, and multiple accommodation modules mounted on each tier of the rack and each of which stably secures an electric kick scooter. With the use of the movable station, many electric kick scooters can be picked up easily and stably carried. In addition, damage to the electric kick scooters and stable placement frames can be prevented during transportation of the electric kick scooters.

A tiltable trailer that can assume a high, or road, position, and a low loading position in which the trailer is tilted with respect to the ground. The trailer includes wheels; a chassis mounted on an axle that pivots with respect to the wheels; an actuator for actuating the pivoting of the axle relative to the wheels to vary the position of the chassis with respect to the ground, the actuator including a flexible element secured to the axle and a tensioner attached to the chassis for adjusting tension of the flexible element; and a lock for locking the trailer in the high position, which is separate from the actuator. The lock includes a sliding locking bar, a first end of which is secured to the axle and a second end of which cooperates with a locking mechanism, mounted on the chassis, when the trailer is in the high position.

This present invention relates to a missing wheel chock alert device that features a flag or indicator system on one side of the device that is easily visible to a vehicle operator through the side view mirror. The wheel chock alert device provides notification to an operator regarding a missing, lost, or unsecured wheel chock; and therefore, ensures that the vehicle operator does not leave the wheel chock(s) at jobsites and other areas. Additionally, the wheel chock alert device offers ease and convenience when identifying the position and status of the wheel chock, and ensures the wheel chock remains secure.

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.
