Abstract: A rolling gate of the invention has two gate parts movable toward or away from each other from opposite sides of a gate opening; carriage tracks mounted above the gate opening; a running carriage connected to each gate part and movably mounted on carriage tracks above the gate opening to carry each gate part as the gate parts are moved toward or away from each other; a guide member provided on each gate part extending along a front edge of each gate part; an L-shaped force transmitting element for each gate part, a first end of which is pivotally connected to and slidable along the guide member of that gate part and a second end of which is pivotally connected to a stationary member, advantageously the frame of the gate, and a linear drive for each gate part, which can be a hydraulic or pneumatic drive, including an extendible driven member connected to one of the force transmitting elements to pivot the force transmitting element and thus move the movable gate parts to or from each other to open and close th

Abstract: A sealing arrangement for a loading door has three flexible sealing elements extending along two lateral edges and one upper edge of a door opening and movable between an inoperative position in which the flexible sealing elements are located in the plane of the door opening, and an operative position in which they are withdrawn from this plane and extend into the interior of a container or the like so as to abut against the inner walls of the latter. The proximal end portions of the sealing elements overlap one another.
