A cargo restraint includes a housing. The cargo restraint further includes an inner pawl and an outer pawl coupled to the housing and configured to rotate between a retracted position and an erected position relative to the housing. The cargo restraint further includes a locking pawl rotatably coupled to at least one of the inner pawl or the outer pawl and configured to rotate between a locked position in which the inner pawl and the outer pawl are locked in the erected position and an unlocked position.

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.

A pallet hold-down system having a horizontal and vertical movement securement apparatuses and a method of using the system where a rotatable member is interconnected with a vertical and a horizontal movement securement apparatus such that rotation of the rotatable member simultaneously locks both the vertical and horizontal movement securement apparatuses to prevent horizontal and vertical pellet movements.

Methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

Various devices, methods, and media are provided. According to one of the devices, an unlocking request for unlocking a lock is received. The lock is provided in a container and contains a physical object. Information of a first owner, that has a right of ownership of the physical object, is acquired from a first ledger when the unlocking request is received. The first ledger is one of a plurality of distributed ledgers which each have a same content. The device determines whether the first requester matches the first owner, and causes the lock to be unlocked when the first requester matches the first owner.
