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.

The invention relates to a driverless transport vehicle for moving a semi-trailer. The driverless transport vehicle comprises a base body and a telescopic arm protruding from the base body, said telescopic arm comprising a surroundings detection device on one end facing away from the base body. The invention also relates to a method for moving a semi-trailer using a driverless transport vehicle.

The invention relates to a driverless transport vehicle for moving a semi-trailer. The driverless transport vehicle comprises a coupling device for automatically coupling the driverless transport vehicle to a kingpin of the semi-trailer. The invention also relates to a method for moving a semi-trailer using a driverless transport vehicle.

An industrial vehicle includes a frame, a counterweight that is connected to a rear part of the frame and a drive device that drives rear wheels. The drive device includes a drive device body and a pair of damping members that is mounted to the counterweight on right and left sides of the drive device body and allows relative motion between the counterweight and the rear wheels. The counterweight has a left mounting portion and a right mounting portion that are formed by machining. The left mounting portion and the right mounting portion have a first mounting hole and a second mounting hole, respectively, through which the respective damping members are mounted to the left mounting portion and the right mounting portion. The first mounting hole and the second mounting hole are formed coaxially with each other.

A towing tractor includes a frame, a counterweight that is connected to a rear part of the frame, and a plurality of component parts supported by the frame. The frame includes a plurality of frame assemblies that are connected to each other by bolts. Each frame assembly includes a plurality of frame members. Each frame member is selected according to the component parts, from a plurality of members to be selected that is different from each other in at least one of dimensions in a longitudinal direction and a width direction of the frame.

A container transportation system using autonomous driving includes: a container to be transported; an autonomous vehicle docked with or undocked from the container and autonomously travelling to transport the container to a transport destination; and a management server controlling travelling of the autonomous vehicle, wherein the autonomous vehicle comprises a container coupling part coupled to the container, and the container comprises: a container body; a plurality of height adjustment pillars coupled to respective corners of a lower surface of the container body and adjustable in length to lift or lower the container body from or to the ground; and a vehicle coupling part formed on the lower surface of the container body and coupled to the container coupling part.

Articulated vehicles and trailers configured for highway transportation, where the tractor of the articulated vehicle is configured to operate in an autonomous mode. In such articulated vehicles, the trailer can be removably coupled to the tractor via a kingpin. The tractor, when coupled to the trailer via the kingpin, and aligned with the trailer, fits entirely beneath the trailer, the tractor being operable to tow the trailer when coupled to the trailer.

A terminal tractor, comprising: (a) an operator cab, (b) a fifth wheel configured for repositioning trailers, and (c) a trailer stabilizer lift separate from the fifth wheel.

A portable trailer stabilizer includes a support surface engagement element, a trailer engagement element, a hydraulic cylinder that extends the trailer engagement element relative to the support surface engagement element, an on-board, self-contained energy source including a hydraulic accumulator for the hydraulic cylinder, an isolation valve fluidically interposing the hydraulic cylinder and the hydraulic accumulator, a positioning element engagement element to selectively couple with a trailer stabilizer positioning element of a tractor, and a valve operator mechanism to (i) open the isolation valve when the positioning element engagement element is coupled to the trailer stabilizer positioning element of the tractor, and (ii) shut the isolation valve when the positioning element engagement element is uncoupled from the trailer stabilizer positioning element of the tractor. The hydraulic cylinder, the hydraulic accumulator, and the isolation valve are operatively connected in a closed hydraulic system containing a hydraulic fluid.
