A portable multi-functional system having a multi-functional apparatus customizable by way of devices arranged to respectively perform different functions, and a container arranged to be transported by way of ground, naval or air transportation and having predetermined external dimensions is provided. The multi-functional apparatus is secured to the container, and is arranged to take at least two types of layout: a first layout or transport layout wherein the multi-functional apparatus is inside the predetermined external dimensions and a second layout or lifting up layout wherein the multi-functional apparatus projects from the predetermined external dimensions of the container so as to realize a tower. The invention also relates to a method for realizing the multi-functional system.

A frame rail for a movable barrier includes a top side, a bottom side, a front side, and a rear side. A first module connector is formed on the rear side. The first module connector extends continuously along a length of the frame rail and is configured to slidably receive a corresponding second module connector of a module. The frame rail has a continuous cross-section with the first module connector integrally formed with the top, bottom, front, and rear sides. One of the first or second module connectors comprises a groove and the other of the first or second module connectors comprises a tongue configured for receipt within the groove. The first module connector is configured to slidably receive the second module connector from a longitudinal end surface of the frame rail.

Disclosed is strut for a wind load door comprised of connected portions disposed at angles to one another. The strut comprises a mounting portion, the mounting portion including a fastener mechanism adapted to connect the strut to a panel of the door. The mounting portion is connected with a first oblique portion, a first edge of the first oblique portion connected with the mounting portion at a first edge of the mounting portion, the first oblique portion extending at a first angle with respect to the mounting portion. The mounting portion is connected with a leg portion, a first edge of the leg portion connected with the mounting portion at a second edge of the mounting portion, the leg portion extending at a second angle with respect to the mounting portion. The leg portion is connected with a web portion, a first edge of the web portion connected with a second edge of the leg portion, the web portion extending at a third angle from the leg portion. The web portion is connected with a second oblique portion, a first edge of the second oblique portion connected with a second edge of the web portion, the second oblique portion extending at a fourth angle from the web portion. The strut may include one or more ribs extending along a portion of the mounting portion and the leg portion.

A hinge for a bi-fold door is integrated with a pair of stiles. Each stile has a hinge flange integrated to the stile. Opposing stiles with opposing and aligned hinge flanges collectively create an integral hinge assembly that may be useful in thermal doors employing one or more thermal breaks.

A tank cover, especially a cover on a sewage treatment tank, is provided with an access opening with a liftable hatch cover. Along with the hatch cover is a safety barrier or grate, either connected directly to the hatch cover or to structure surrounding the hatch opening. When the hatch is opened the barrier is deployed to prevent a worker from accidentally falling through the opening. In one form the barrier is pivotally attached to the bottom side of the hatch cover, and can be swung out as the hatch is opened to form an A shaped or roof shaped barrier, with the hatch cover and the barrier both inclined and essentially forming a roof over the opening. Braces or struts hold these components in the erected position and provide barriers from the sides. For entry of a person through the opening, the barrier or grate can be retained against the bottom of the hatch cover as the cover is swung fully open, through 180. In another form the barrier is secured to tank cover structure just below the hatch cover and can be left in place as a horizontal barrier when the cover is fully opened. For access into the tank the barrier/grate can be swung back in the same direction as the access cover and stacked on the opened access cover.

Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.

A container inspection device and a container inspection method for inspecting containers are provided. The container inspection device comprises at least one light fixture for illuminating containers at a predetermined inspection instant of time for inspecting the containers, and an electrical line for connecting the at least one light fixture to an electrical energy supply and to a bus system, so that the electrical line serves both to supply the at least one light fixture with electrical energy and to connect with a real time data network.

A high load retention system for a sectional overhead door enables uninhibited operation of a standard roller track mechanism of a sectional overhead door, while allowing high wind loads to be seamlessly transferred from the track mechanism to a more robust high load jamb retaining element. The system comprises: a plurality of primary door panels, each having a front face; a primary track; engagement elements each having a first end connected to a primary door panel and a second end that rides in the primary track; a high load jamb retaining element positioned adjacent to the primary track and having a clasping portion; and a high load door retaining element connected to a primary door panel and having a clasping portion corresponding to the clasping portion of the high load jamb retaining element.
