A material vehicle (10) comprises a vehicle body (101), an unlocking assembly (102), a plurality of front universal wheels (103) and a plurality of rear universal wheels (104), wherein the plurality of front universal wheels (103) and the plurality of rear universal wheels (104) are all in a locked state; the vehicle body (101) is used for placing a target article; the unlocking assembly (102) is used for releasing the plurality of front universal wheels (103) from the locked state when same are in a horizontal rotation direction, and controlling the material vehicle (10) to travel in a first direction by means of the plurality of front universal wheels (103); and the unlocking assembly (102) is further used for releasing the plurality of rear universal wheels (104) from the locked state when same are in the horizontal rotation direction, and controlling the material vehicle (10) to travel in a second direction by means of the plurality of rear universal wheels (104), the first direction and the second direction being opposite to each other. By means of the unlocking assembly, the plurality of front universal wheels or the plurality of rear universal wheels can be released from the locked state thereof, such that the material vehicle can change the positions of driving wheels, and bidirectional traveling can be realized without needing to turn the material vehicle around.

The disclosure is directed at an apparatus and method for shifting or moving trailers. In one aspect, the apparatus is a converter dolly with at least one set of powered wheels, which can be equipped with a remote control steering device. In another aspect, the apparatus is a remotely controlled terminal tractor configured to be coupled to a trailer. In some aspects, the remote control of the apparatus is directed by an autonomous algorithm resident remotely or on the apparatus itself. In another aspect, a frame of an apparatus for towing a trailer includes an articulated frame with a first frame counterpart pivotably connected to a second frame counterpart.

A guiding vehicle (100) for an intralogistics system, wherein the guiding vehicle (100) is remote controlled or autonomous and configured to be connected to a self-propelled load bearing cart (200), and guide and control the propulsion of the self-propelled load bearing cart (200) such that the load bearing cart (200) can transport a load in the intralogistics system. The guiding vehicle (100) comprising a mechanical connector (170) for mechanically connecting the guiding vehicle (100) to the load bearing cart (200) and a connector for transferring data. The guiding vehicle (100) is configured to receive navigation data from the self-propelled load bearing cart (200), using the connector for transferring data, in the form of information concerning the movement of a drive wheel of the load bearing cart (200) obtained from at least one motor of the load bearing cart (200) or from at least one encoder connected to the drive wheel.

An auxiliary dolly attachable to the rear of a primary trailer includes a first portion attachable to the primary trailer, a second portion comprising one or more axles with wheels, and a pivot point at which the first portion is coupled to and movable relative to the second portion, and further includes one or more cylinders configured to adjust the first and second portions relative to each other and apportion weight between the primary trailer and the auxiliary dolly.

An unmanned and self-powered vehicle or Towable Autonomous Dray (TOAD) may follow a vehicle and tow a trailer, haul a load, and/or recharge a pilot vehicle. The TOAD may be semi-autonomous and may attach to a pilot vehicle by an electronic identification. Further, wireless charging of the pilot vehicle may be provided by the TOAD. Smart trailer brakes, electric trailer axles, and a mechanically coupled tow vehicle may be provided by the TOAD in combination with additional units. A smart trailer controller may include a smart head unit and a smart tail unit in a trailer that may offer trailer security and increased safety. A smart trailer brake controller on the pilot vehicle and a smart module on the trailer may be applied where no unmanned vehicle is employed, such as, in a classic pick-up/trailer combination.

An improved cargo dolly for transporting cargo is described having a mobile dolly frame, a main shaft on the frame, a lever proximate to a first part of the frame (where the lever is movable relative to the frame and in responsive communication with the main shaft), a first set of transfer sprockets mounted to the main shaft, a secondary shaft rotatably disposed at a second part of the frame (where the first part is remote from the second part), a second set of transfer sprockets mounted to the secondary shaft, a chain disposed about the first set of transfer sprockets and the second set of transfer sprockets, and a locking pin having a first end fixed to the secondary shaft and a second end configured as an angled latch. Rotation of the lever responsively causes the locking pin to remotely rotate at the second part of the frame.
