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: 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.
