A liquefied gas unloading and deep evacuation system may more quickly, more efficiently and more completely unload liquefied gases from transport tanks, such as rail cars, into stationary storage tanks or into truck tanks. The system may utilize a two stage compressor, an electric motor, a variable frequency drive, a four way valve, a three way valve, a two way valve, a programmable logic controller based control system and pressure and temperature transmitters. The valving enables deep evacuation of the transport or supply tank to more completely empty the transport tank. The programmable logic controller and variable speed drive may be used to variably control the speed of the two stage compressor so that the system may be running as fast as possible during changes in ambient temperature and/or different stages of offloading the liquefied gases without exceeding the compressor's horsepower limit.

A system, method, and apparatus for palletizing cargo on a rack for shipment are provided. The system generally includes a tiered rack having a base tier, a support framework extending from the base tier, and a second tier adjustably attached to the support framework. The system may further include a plurality of lower frame support members positioned longitudinally across the bottom of the base tier, and a plurality of pneumatically actuated rollers spaced to cooperatively engage the plurality of lower frame support members, the rollers being selectively extendable from a plurality of raised tracks positioned longitudinally along a floor of the railcar, where the rollers are configured to pneumatically extend past an upper surface of the track when actuated and allow for linear motion thereover.

Disclosed are various embodiments for a containerized shipping trailer and an automated module moving apparatus. A containerized shipping trailer may comprise a shipping container having a plurality of compartments configured to store a plurality of modules in an interior of the shipping container. An automated module moving apparatus may comprise a body configured to move horizontally along a rail from a first position to a second position to insert at least one projection into a portal of a module located in a compartment of the shipping container. The module may be removed and placed at a predefined location.

Disclosed herein is a movable platform and an extension assembly which enables the width or length of the movable platform to be extended. The extension assembly comprises a plurality of clips which releasably engage openings on the movable platform. A top surface of the extension assembly is flush with a top surface of the movable platform.

A shuttle van system for a container terminal, including: at least one rail and a transfer device. The transfer device includes a plurality of shuttle vans and a plurality of transition platforms. Each shuttle van includes: a base frame, a wheel group, a wheel driving device, a lifting device, and a supporting plate. Each transition platform includes brackets. The shuttle vans run on the rail between the brackets. The lifting device of the shuttle van is configured to lift the container from the supporting plate. The container is transferred from the supporting plate of the shuttle van to the bracket after contraction of the lifting device.
