According to the present embodiment, a serving module includes: a tray; a main body formed therein with a tray space configured to accommodate the tray and having a tray entrance; a tray moving device configured to move at least a part of the tray out of the tray entrance or move an entire of the tray into the tray space; a door configured to open and close the tray entrance; and a door driving device connected to the door to open and close the door.

A vehicle transporting device includes a bogie frame, a device main body, and an upright frame. The upright frame connects a tip portion of the bogie frame and the device main body. The bogie frame includes two frame members and at least two pipes, which are disposed parallel to a longitudinal direction of the bogie frame. The two frame members are disposed parallel to the at least two pipes at a position outside the at least two pipes in a width direction of the bogie frame. The at least two pipes include two pipes facing each other in the width direction. A reinforcing member extending in the width direction is provided at the tip portion of the bogie frame and between the two facing pipes. The two frame members, the reinforcing member, and the upright frame are connected to each other at the tip portion of the bogie frame.

The present invention provides a tiering device for a freight compartment, which pertains to the technical field of logistic and transportation equipment. It solves the problem in the prior art that existing tiering devices for a freight compartment occupy a relatively large space inside the freight compartment. The tiering device for a freight compartment according to the present invention comprises: a sidewall of the freight compartment, a transmission part, and a vertical guide track; the transmission part lift/lower support members, the support members forms placement area for goods. Half of the transmission part is buried inside a belt guide channel on the vertical guide track, the other half is located inside the vertical guide track or is flush with the groove opening of the vertical guide track. The present invention occupies less space inside the freight compartment, thus facilitating loading/unloading goods to/from the freight compartment.

A motorized horizontal support system may include first and second vertical tracks that are configured to be installed upon opposing walls of a cargo compartment; first and second brackets that each slide along the respective first and second vertical tracks; a horizontal support disposed between and fixed with respect to the first and second brackets, where the horizontal support includes a first inner passageway extending along a length of the horizontal support; a first balance cable extending through the first inner passageway of the horizontal support; a motor operatively engaged with the second bracket, where operation of the motor may cause the first and second brackets to slide upwardly or downwardly along the respective first and second vertical tracks; and a controller with user input capability that may selectively control the operation of the motor.

Provided is a mobile body system including a traveling unit having an autonomous traveling function and a trolley unit having a housing portion for loading an object. A detection unit detects an amount of objects placed on the housing portion. A control unit determines an operation of the traveling unit based on the amount of objects detected by the detection unit.

This invention corresponds to a mechanism for loading and unloading materials for a container, comprising at least one guide located inside the container; at least one rigid panel connected by means of a first sliding element to the side guide, where said side guide allows the displacement of the rigid panel along a first direction. Furthermore, the mechanism of this invention includes a loading panel connected to the rigid panel, said loading panel being arranged parallel to a floor of the container.

This disclosure provides a bushing for a captive beam system, and specifically a bushing that extends between a track for a captive beam system and a bracket that slides along the track. In some captive beam systems that have automatic moving capability, the bracket (and therefore the captive beam that is rotatably connected to the bracket) is pulled upward or downward by a force applied thereto either directly or indirectly, and this force may result in some rubbing between the bracket and the track, which introduces the possibility of wear. The bushing is provided as a wear surface to prevent track or bracket wear. The disclosure also provides a tensioning system for an automatically movable captive beam.

A rack and lifter system and method is described. The system includes a rack having at least a first engagement opening, and a lifter having at least a first engagement member and at least a first vertical extension member, wherein in use the at least a first engagement member interlocks with the at least a first engagement opening of the rack, and the at least a first vertical extension member extends to lift the interlocked lifter and rack, wherein the at least a first vertical extension member includes means for movement. The lifter may include a guiding-and-lifting member which lifts the lifter and guides the lifter into an interior space of the rack. The lifter may include a towing machine connection member which connects the lifter to a towing machine which positions the lifter within the rack and tows the connected lifter and rack.
