A storage tank includes a floor, a roof, a sidewall extending between the floor and the roof, an access hatch provided on the roof and having a base, a lid pivotably coupled to the base, and a latch configured to secure the lid to the base in a closed position, and a system for remotely opening and closing the access hatch. The system includes an elongate arm having a proximal end operatively coupled to the lid, a pull cable attached to a distal end of the elongate arm and extending toward a ground adjacent the storage tank, and a latching cable attached to the latch and extending toward the ground adjacent the storage tank, wherein pulling on the latching cable when the lid is in the closed position actuates the latch to secure the lid to the base in the closed position.

A tailgate assembly includes a tailgate hinge that is operable to attach a tailgate to a vacuum tank such that the tailgate is movable between an open position and a closed position, the vacuum tank operable to withstand vacuum pressure when the tailgate is in the closed position. A tailgate warming tube loop is operable to circulate a heated fluid through the tailgate, the tailgate warming tube loop attached to an interior surface of the tailgate and a first rear pipe flange that includes a first rear pipe flange warming channel in communication with the tailgate warming tube loop.

The invention relates to an assembly (10) of a tank container (20), an inliner (40) and a connection unit (60) for the transport and/or storage of a liquid. The inliner is present in the tank container and the outlet of the inliner is connected to the drain hole (25) of the tank container. A connection unit is present that secures the connection of both outlets and at the same time provides a liquid tight and an air tight connection with an external unit for the delivery or discharge of the liquid contents.

The invention refers to an equipment (1) including a container (19) for the storage of a liquid (2) as well as thermal insulation panels (12,13), wherein none of the thermal insulation panels (12,13) is mounted directly on or even in contact with an outer surface of the container (19), wherein a chamber (5) housing the container (19) is delimited by an enclosure (6) consisting of walls (7), a floor (8) and a ceiling (9), and which is accessible through an access opening, either in the form of an entrance opening in one of the walls (7) closeable by a door or in the form of a manhole (11) eccentric to the center of the ceiling (9) and closeable by a lid (10), wherein the lid (10) or the door is thermally insulated at the inner side and is provided with an air-tight sealing all around, and wherein an inner surface of the chamber (5) except the access opening is entirely covered with the thermal insulation panels (12,13) in such a way that a volume of space occupied by the container (19) is smaller than a volume of space delimited by the inner sides of the thermal insulation panels (12,13) at the inner side of the walls (7), the ceiling (9) and the floor (8), leaving a space for maintenance between the outer surface of the container (19) and the thermal insulation panels (12,13) mounted to the inner surface of the chamber (5), which is only filled with air and is free of any liquid or bulk material in order to keep the container and the bottom of the chamber visible for inspection, and wherein the only way for heat to leave the air-filled space for maintenance between the outer surface of the container (19) and the thermal insulation panels (12,13) is through these thermal insulation panels (12,13) and neither besides such thermal insulation panels (12,13) nor through any kind of air duct or acitve or passive venting.

An automatic hatch assembly for bulk material containers includes a hatch cover which covers a fill opening of the container, and may be retrofitted to existing containers equipped with a conventional hatch cover. A drive unit is operable to open and close the hatch cover, and a locking assembly actuates an extendable lock member. Optionally, a pneumatic seal is provided within the cover for sealing the container from the outside environment. The locking assembly is adapted to resist opening forces applied to the cover, such as when the container is pressurized, and a sequencing controller may be provided to facilitate automated operation of the opening/closing, locking/unlocking, and/or sealing/unsealing of the hatch cover.

A method for installing trays in a case where a plate tower is horizontally placed or approximately horizontally placed. No manhole is formed on a cylinder body of the plate tower, so as to reduce damage to the cylinder body of the plate tower, thereby improving the airtight performance of the plate tower. Since the trays are installed in a case where the plate tower is horizontally placed or approximately horizontally placed, manual operations are facilitated, manual working is reduced, and the potential safety hazard caused by high-place operations is avoided.
