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.

A cargo restraint system may comprise an inner shaft and a first outer tube coaxially configured to rotate about an axis and a first restraint located about the first outer tube and configured to rotate about the axis. A second outer tube coupled to the inner shaft configured to rotate about the axis and a second restraint located about the second outer tube and configured to rotate about the axis. The first restraint and the second restraint may include a head configured to rotate about the axis and a plunger configured to translate between an engaged state and a disengaged state.

A system and method for monitoring one or more objects that have been restrainedly secured to a vehicle by one or more restraint members. The system includes a plurality of sensors each configured for monitoring one or more of a compressive or tensile stress or strain in one of the one or more restraint members, and a controller for periodically interrogating each of the plurality of sensors to ascertain a value of stress or strain detected by the respective sensor. When a change in the value of stress or strain is indicative of loosened or overtightened restraint members, a mitigation event is triggered.

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.

The present disclosure provides a trailer and a vehicle. The trailer comprises: a structural beam; and at least one container protector installed on the structural beam; wherein the container protector comprises a drive member and a protection member, the drive member being adapted to drive the protection member to rise and lower, and the protection member being capable of providing a limiting function for a container on the trailer when raised. The present disclosure may automatically raise the protection member after installing the container on the trailer so that the protection member locks the container; before the container is to be unloaded, the protection member is automatically retracted to release the limiting function for the container. In this way, it is no longer necessary to specially manually tighten or loosen a shackle of a container, realizing the intelligent control of cargo loading and unloading.

A locking mechanism has a guide and a vertically movable plate. The plate is movable in the guide under gravitational influence between a locked position and an unlocked position. A slot is formed in the plate to receive a guide pin. The guide pin maintains the movable plate in the guide. The slot enables axial vertical movement of the plate in the guide. The plate moves into the locked position upon contact with a surface. In this position, the plate projects from the guide to lock a roll off container onto the hoist. The movable plate reverts to the unlocked position upon removal of the surface so that the plate moves into the guide.

A cargo restraint assembly may comprise a first bracket slidingly coupled to a housing. A retention block may be pivotably coupled to the first bracket. A second bracket may be slidingly coupled to the housing. The first bracket may be coupled to the second bracket via a spring. The first bracket and the second bracket may be configured to attenuate in response to a cargo deck bending during transportation of cargo in an aircraft.

Disclosed herein concerns an industrial truck for transporting a container on a support frame including a vehicle frame with height-adjustable wheel suspensions and engagement means for fixing a support frame which can be picked up by the industrial truck. Further disclosed herein is a self-supporting support frame suitable to interact with the industrial truck.
