A tie-down assembly for selective attachment to a structure at an oblong aperture defined thereby and detachment therefrom includes an anchor arranged along an axis. The anchor has an oblong-shaped section configured to be inserted into the structure's oblong aperture. The anchor also has a knob section which turns the anchor's oblong-shaped section about the axis when a torque is applied to the knob section. The assembly also includes a rail mount configured to abut the oblong-shaped section, and defining a pocket for accepting the knob section and limiting rotation of the oblong-shaped section via contact with the knob section. The anchor's oblong-shaped section and the rail mount are together configured to sandwich therebetween material of the structure proximate the oblong aperture after the anchor's oblong-shaped section is inserted into and turned relative to the oblong aperture to thereby attach the tie-down assembly to the structure.

An intermodal container mobilizer that includes a tow vehicle and forward and aft intermodal shipping container attachments. The forward container attachment is carried by the tow vehicle and connects to one end of an intermodal container. The aft container attachment is wheeled and connects to an opposite end of the intermodal container. The forward and aft attachments, together with the tow vehicle, support the intermodal container for rolling transport across a flat surface.

A surface mount assembly may comprise at least one connector set, including a mount anchor and mount fitting that are configured to lockingly engage, and a remote release assembly for unlocking the two. The surface mount assembly may include a catch to catch the mount fitting as it drops from engagement with the mount anchor. The surface mount assembly may further include a guide member for guiding the mount fitting into engagement with the mount anchor. The surface mount assembly may further include a case mount assembly that is crashworthy, in that it is configured to transfer the loads from cargo contained in the case to the mount fitting, while largely bypassing the case. The surface mount assembly may also include two connector sets, where the remote release assembly is disposed between the two and is configured to simultaneous release each of the two from engagement.

Fixtures for supporting wind turbine blades that have a root end flange, which may be interconnected with twistlock fasteners and stacked for use in plural modes of transportation, including ocean transportation. A root fixture includes a bearing that rotatably engages a mounting flange adapter that is coupled to the blade's root flange. A bearing pivot is coupled to the bearing to allow the blade to pivot during loading, unloading and transport. A tip stand assembly is provided to engage the blade along a tip end support region.

A system for lifting shipping containers each having corner fittings provided with lifting/fastening apertures, the system including lifting means for lifting en masse a matrix of containers including two or more columns of vertically connected containers, each column being at least two containers high. The lifting means uses the lifting apertures provided on the top of the top container in each column, and connecting means are provided for connecting each column transversely to each adjacent column to hold the columns together and prevent toppling of the columns relative to each other. A method of lifting is also disclosed together with a lifting beam and trailer and for use in handling containers.

A railcar locking system includes an elongated tower having an outer rail configured to engage with a lower railcar via a restrain cone; a locking arm extending from the elongated tower; a first locking cone secured to the locking arm and configured to engage with the lower railcar; and a second locking cone secure to the locking arm and configured to engage with an upper railcar.

A locking device for containers on a vehicle chassis, having a housing, a plug-in pin which is mounted displaceably in the housing and/or a rotary pin which is mounted rotatably in the housing, wherein the plug-in pin and/or the rotary pin can be moved between an open position and a locked position. The invention was based on the problem of providing a locking device for containers which is triggered automatically by way of the loading operation. According to the invention, the problem is solved by the fact that a spring element which interacts with a triggering element acts on the plug-in pin or the rotary pin, wherein the triggering unit has at least one sensing bolt which protrudes out of the housing in the direction of a container fitting in the open position.

Embodiments of the present disclosure include a trailer assembly for transporting a plurality of proppant containers along a roadway, and associated methods. The trailer assembly includes a skeletal frame having open areas between structural components to enhance weight reduction of the frame, and first, second, third, and connector sections. Additionally, the frame includes a pair of spaced-apart side rails and three or more wheel and axle assemblies to facilitate movement of the trailer assembly. The trailer assembly includes a first pair of outriggers coupled to and arranged transverse the pair of side rails, and a second pair of outriggers arranged proximate the first pair of outriggers. The outriggers have a coupling element positioned at each distal end to engage and secure a proppant container of the plurality of proppant containers to the trailer assembly. Each distal end is positioned to extend outwardly from an axis of the trailer.
