A restraint for use in restraining cargo includes a main body having an elongated shape with a contact end configured to contact and restrain the cargo and a second end opposite the contact end, the contact end defining a first face and a second face such that a first angle between the first face and the second face is at least one of less than or equal to 160 degrees. The restraint further includes a spring configured to allow the main body to rotate relative to a stationary object in response to contact with the cargo and to cause the main body to return to a neutral position in response to a lack of contact with the cargo.

The present disclosure provides a container locking device and a piggyback transport vehicle. The container locking device comprises: a support, the support being provided with an accommodating space; a locking structure, a first end of the locking structure being hinged with the support, the locking structure having a locking position extending out of the accommodating space and an avoiding position retracted into the accommodating space; and a support structure, a first end of the support structure being hinged with a second end of the locking structure; wherein in a direction away from the locking structure, the support structure has a retraction position and a support position which cooperates with the support; when the locking structure is located at the locking position, the support structure is located at the support position and the locking structure is caused to stay at the locking position; and when the locking structure is located at the avoiding position, the support structure is located at the retraction position and is retracted into the accommodating space. The container locking device is an inward-overturning type and supports the locking structure by a support structure, and compared with an outer-overturning cantilever structure, the container can be supported and locked more reliably and stably.

Described herein are systems and methods for using different truck types for deliveries. A package is initially loaded into a specially configured cargo container that can be transported either on a primary truck or a secondary truck. A secondary truck is smaller than a primary truck and is configured to transport fewer cargo containers than the primary truck. An initial leg of the overall delivery (e.g., from a warehouse to a transfer point) is performed using a primary truck. The cargo container is then transferred to a secondary truck, which completes the delivery. Empty cargo containers can be transferred back to a primary truck, e.g., in a stacked or folded manner, for transporting back to the warehouse. The configurations of primary and secondary trucks are such that these transfers can occur at any location (e.g., a parking lot) with minimal human involvement.

A cargo restraint system includes a driving shaft, a first restraint, and a second restraint. The first restraint is operatively coupled to the driving shaft via a first indexing mechanism arrangement. The second restraint is operatively coupled to the driving shaft via a second indexing mechanism arrangement. The first and second indexing mechanism arrangements are arranged such that rotation of the driving shaft in a first rotational direction causes the first restraint to rotate between a lowered position and a raised position, and further rotation of the driving shaft in the same rotational direction causes the second restraint to rotate between the lowered position and the raised position. The first restraint may be axially offset from the second restraint to allow sequential loading and unloading of cargo.

A support structure for supporting vehicles one above the other during transport or storage, the structure comprising a base frame having four corner posts extending generally vertically when in use to support a separate upper frame on which an upper vehicle can be supported in an elevated transport position, and one or more separate lower frames arranged to be positioned within the base frame when in use on which a lower vehicle can be supported. The upper frame is guided up the corner posts when the upper vehicle is raised to the elevated transport position. The base frame, upper and lower frames are transportable in a collapsed state when not in use by folding the corner posts down and collapsing the base frame, upper frame and lower frame so that they occupy less space with the upper, and lower and base frames in a nested configuration.

A modular portable storage container system includes a storage container having first and second sections. The first section defines a first partial volume of storage space and the second section defines a second partial volume of storage space. The system further includes a lock mechanism with a lock arm, lock handle, and pivot shaft defining an axis of rotation. The lock arm and handle are fixed for common rotation with the pivot shaft. The arm extends radially outward from the pivot shaft to a roller assembly. A lock track is disposed within the second section and extends from a fluted open portion to a closed end, with a continuous track portion disposed therebetween. The first and second sections are movable between at least closed and open positions. In the closed position, the roller assembly engages with the lock track and retains the first section in contact with the second portion.

A coupling mechanism securing a first object having a well to a second object having a lug, including a shuttle movable within the lug, a resilient biasing means biasing the shuttle away from a base of the well when the lug is inserted, and locking elements movable radially in the lug between a retracted position and an extended position. Each locking element moves from the retracted position and retains in the extended position by a surface profile of the shuttle. The coupling mechanism includes a movable stop having: a first position in which movement of the shuttle is limited so the locking elements interact with the surface profile, and a second position in which movement of the shuttle is extended to cause the locking elements to interact with another surface profile of the shuttle, moving the locking elements from their extended position to their retracted position.
