The U-shaped member is slidably mounted to the mounting part and including a first end and a second end. A retracting system is included that causes the U-shaped member to move to a retracted position when the U-shaped member experiences a predetermined external force sufficient to disengage the locking system. The retracting system has at least one of (a) first and second biasing mechanisms wherein the first biasing mechanism biases the first end towards the retracted position and the second biasing mechanism biases the second end towards the retracted position, or (b) an actuator, wherein the actuator moves the U-shaped member towards at least one of the extended position and the retracted position. The U-shaped member is movable between the extended position whereby at least a portion of the U-shaped member is positioned above an upper surface of the mounting part, and the retracted position whereby the U-shaped member is positioned approximately flush with or below the upper surface of the mounting part.

A low elevational profile of each of a pair of first and second wheel chocks for restraining a current “low-drag” motor vehicle in a carrier, such as a railway car, is derived from each wheel chock having an internally webbed, elongated stepped-box body terminated with a relatively short rectangular box having its inner wall integrally formed with the stepped-box body. The body of the first chock is essentially a mirror-image of the second chock body. The low profile of a wheel chock allows each to be positioned under a vehicle the rocker panel of which has its lower edge only 148 mm (5.82 inches) above the surface upon which the vehicle's tire rests, so that the installed chock height is reduced to 47.6 mm (1.87″) under the components of the vehicle's body. The assembly may include a pair of “active” chocks; or, one active chock and one anchor chock. A single window in the upper portion of the stepped-box provides access for a strap of a wheel harness, which strap is wrapped around a torque tube in an active chock. The torque tube in one chock is rotatable in a direction opposite to that of the torque tube of the other chock. With a pair of active chocks, hooks on straps of a prior art harness are eliminated because it is difficult and time-consuming to manipulate a tire harness with its straps and hooks to secure the tire between the wheel chocks. When one chock is an anchor chock, one end of the strap is provided with a hook which is anchored to a rod or tube which is substituted for the rotatable torque tube.

The invention relates to a transportation method and a package system for transporting a set of large longitudinal items such as blades for a wind turbine (1) or a tower for a wind turbine. Taking wind turbine blades (1) as an example, the advantages of the invention reside in packaging a tip (3) of one blade and a base (2) of a second blade in the one and same package (5) such that two blades (1) may be transported in packages (5, 16) having an overall lateral extension, approximately the same as the base of only one blade (1) for the wind turbine. Thereby a very compact but also a very easy means of transportation of large longitudinal items such as wind turbine blades (1) is provided.

Disclosed is a cargo space divider wherein a system of dividing walls allow a cargo space, preferably a pick-up truck bed, to be sectioned off into smaller, variably sized sections in order to prevent objects transported therein from rolling or sliding about the bed. The device consists of a pair of support rails that are installed along and clamped to the sidewalls of the truck bed above the wheel wells. Lateral sectioning walls span the width of the truck bed and longitudinal sectioning walls span between the lateral sectioning walls, both in adjustable positions, thus creating divided cargo spaces that are adjustable both in number and size.

The methods and apparatus for transporting compressed gas includes a gas storage system having a plurality of pipes connected by a manifold whereby the gas storage system is designed to operate in the range of the optimum compressibility factor for a given composition of gas. The pipe for the gas storage system is preferably large diameter pipe made of a high strength material whereby a low temperature is selected which can be withstood by the material of the pipe. Knowing the compressibility factor of the gas, the temperature, and the diameter of the pipe, the wall thickness of the pipe is calculated for the pressure range of the gas at the selected temperature. The gas storage system may either be modular or be part of the structure of a vehicle for transporting the gas. The gas storage system further includes enclosing the pipes in an enclosure having a nitrogen atmosphere. A displacement fluid may be used to offload the gas from the gas storage system. A vehicle with the gas storage system designed for a particular composition gas produced at a given location is used to transport gas from that producing location to a receiving station miles from the producing location.

A securement mechanism includes a tie down cleat assembly for engagement with a mating component, the tie down cleat assembly including a pin, a lock plate adjacent one of the ends of the pin, and a housing with an aperture receiving the pin. An actuating member is operationally connected to the pin and causes selective movement of the pin and lock plate between a secured and unsecured orientation. The lock plate includes two dimensions, a first dimension permitting the lock plate to be inserted into a channel associated with the mating component and a second dimension permitting the securement of the mating component between the housing and locking plate. The pin and locking plate and preferably the housing all rotate as a single unit.

Tension alert device is attached between opposing ends of a securing member attached to a load bed to secure a load thereupon. The device has a strip with a curved portion, which is resiliently movable towards a proximity sensor disposed on a wall in device. When tension in securing member decreases, proximity of curved portion relative wall decreases. When curved portion enters a proximity actuation state relative first wall corresponding to a low tension state where tension is below a tension threshold level, a proximity sensor actuates a signaling device which alerts a user.

Disclosed is a container loading and unloading apparatus, which overcomes a problem of a conventional container in that a special equipment such as a forklift truck, a crane or the like is necessarily mobilized whenever the loading or unloading work is performed because the container is simply a cuboidal rigid body. The present invention makes it possible to perform the loading and unloading works of the container main body at the time of its storage and transportation without a separate loading and unloading equipment by providing a container supporter to secure a space for loading the container main body on a chassis of a freight car, thereby reducing equipments and labor as well as facilitating the loading and unloading works.
