A tugger train trailer (1) with a chassis (2) and a transport device (7) is disclosed and configured to hold at least one cargo carrier (LT) having rollers (R), wherein the tugger train trailer (1) is provided with at least one locking means (20) that secure the received cargo carrier (LT) in the transverse direction (Q) of the vehicle of the tugger train trailer (1). The locking means (20) has a locking element (21a; 21b) that can be electro-mechanically actuated between a locked position and an unlocked position, wherein the locking element (21a; 21b) is actuated by a spring device (30) toward the locked position and by means of an electric drive device into the unlocked position.

A tugger train trailer is disclosed, including a frame and drive-on surfaces for holding a trolley cart. Transport vehicle drive-on surfaces for an autonomous transport vehicle moving the trolley cart are also provided such that a unit of trolley cart and autonomous transport vehicle can drive on the drive-on surfaces.

An articulated working machine vehicle, such as an articulated hauler, including a front section and a rear section pivotally connected via a connection arrangement configured to control a pivot angle between the front and rear sections for steering of the vehicle, the connection arrangement further being configured to allow the front and rear sections to rotate in relation to each other about a longitudinal axis of the vehicle. The connection arrangement comprises a rotation damper device arranged to transfer dampened relative rotation between the front section and the rear section of the vehicle.

This disclosure relates to systems and methods of towing, hitching, and connecting devices. In particular, this disclosure relates to tow devices, hitches, and connections for towing item containers behind vehicles, both autonomous and manually guided.

A lift device (10) of a tugger train trailer(1) is disclosed for raising and lowering a cargo carried in the tugger train trailer (1). The lift device (10) has a lifting shaft (21) driven by a drive motor (20) and mounted so that it can rotate around an axis of rotation (D), and to which at least one lift linkage (25a; 25b; 25c; 25d) that raises and lowers the cargo is coupled in an articulated manner at some distance from the axis of rotation (D) of the lifting shaft (21).

A vehicle according to a vehicle system and method includes a chassis, a coupler, and a platform on the chassis. The coupler is mounted to the chassis at a first end of the chassis and is configured to releasably connect the vehicle to a second vehicle. The platform is for supporting a cargo container and includes a base portion and a bridge member. The bridge member is located at an end of the platform and is extendable relative to the base portion from a retracted position to an extended position to lengthen the platform. The bridge member in the extended position projects beyond the first end of the chassis, above the coupler, towards the second vehicle for establishing a bridge to transload the cargo container from the platform to the second vehicle.

A cart for transport and storage of items, including odd-size or over-size luggage of airline passengers, comprises a chassis comprising a plurality of wheels, and a storage section comprising at least one shelf. A drawer is provided below the storage section, the drawer comprising a compartment, which is inaccessible when the drawer is in a closed state, in which the drawer is overlapped by a bottom portion of the storage section. The compartment is accessible when the drawer is in an open state, in which the drawer is extracted from and extends beyond the bottom portion of the storage section.

A high capacity cargo/container dolly. The cargo/container dolly includes retractable side stops that actively retract a roller linkage assembly upon retraction of the retractable side stops rather than relying on passive gravitational forces for the retraction. In some embodiments, the retractable side stops are configured to avoid hold up on the cargo during retraction. The retractable side stops may be coupled to a retraction mechanism that may be actuated from either side of the cargo/container dolly, as well as from one or both ends of the cargo/container dolly. The dolly may include aspects that accommodates dynamic loads that occur during transport to mitigate inadvertent retraction of the retractable side stops or spurious release of catch assemblies that retains cargo on the dolly. The dolly may also include self-locking roller assemblies that release only in the presence of cargo, and deck modules that protect the deck roller from road spray contamination.

This disclosure relates to systems and methods of towing, hitching, and connecting devices. In particular, this disclosure relates to tow devices, hitches, and connections for towing item containers behind vehicles, both autonomous and manually guided.

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.
