Abstract: A fork-arm lift tractor includes a vehicle body, a supporting plate disposed above the vehicle body, a lifting device for driving the supporting plate to be lifted, a front and rear fork-arm assemblies, a front and rear fork-arm drive assemblies. The front fork-arm assembly includes two front fork-arms rotatably disposed at the supporting plate. The rear fork-arm assembly includes two rear fork-arms rotatably disposed at the supporting plate, and the front and rear fork-arms may be deployed or retracted from both sides of the supporting plate. The front fork-arm driving assembly includes a front transmission part, and a front power device disposed at the supporting plate and may drive the front transmission part to move horizontally linearly so as to rotate the two front fork-arms. The rear fork-arm driving assembly has almost the same structure of the front fork-arm driving assembly and is used to rotate the two rear fork-arms.

Abstract: The present disclosure relates to vehicle traction apparatus and radiation imaging check systems. One illustrative implementation may comprise two parallel tracks, two sets of traction mechanisms and a driving unit, wherein the tracks are disposed on a ground. The two sets of traction mechanisms may be respectively disposed on the two tracks. Further, the driving unit may be adapted for driving the two sets of traction mechanisms to synchronously move along the two tracks. In some embodiments, each of the two sets of traction mechanisms includes a body, a cantilever, a lifting driving mechanism and a wheel supporting assembly, and may include features such as the body being mounted on the track, the cantilever being disposed parallel to a direction of the tracks, and/or both ends of the cantilever being respectively connected with the lifting driving mechanism and the wheel supporting assembly.

Abstract: A vehicle inspection system is described. The vehicle inspection system comprises: an inspection device, for performing an inspection on a vehicle to be inspected; a carrier platform, for carrying the vehicle to be inspected; and an unmanned controlled travelling device for moving the carrier platform to pass through a scanning area of the inspection device, so as to perform the inspection on the vehicle to be inspected. In the present disclosure, the vehicle to be inspected is carried by the carrier platform, and the unmanned controlled travelling device is used to move the carrier platform to pass through the scanning area of the inspection device, so that the vehicle to be inspected can be subject to inspection smoothly. There is no driver required to drive through the scanning area in this process, thus avoiding exposure of a driver to a threat of radiation.

Abstract: The present disclosure relates to a vehicle positioning apparatus. An implementation may comprise a base provided with a recess, wherein each of two opposite sides of an upper edge of the recess are rotatably provided with a flap, and wherein a power unit may be provided on an outer side of a corresponding flap opposite to the recess. Further, the power unit may be adapted for driving the corresponding flap to transfer between a first supporting position and a second supporting position inclining downwardly, wherein the first supporting position is in a range from a position higher than the second supporting position to a position in a same plane as an upper surface of the base. Such vehicle positioning apparatus may achieve precise positioning of a whole vehicle, such as via the wheels of the vehicle, yielding high positioning accuracy, with simple structure, stable transmission, and low production cost.
