A door operating mechanism for operating longitudinal doors of a railroad hopper car. The mechanism includes operating members that are coupled to ends of the doors. These operating members are each actuated by a separate actuating device that is coupled to a top surface of a sill of the hopper car. Door supports have one end coupled to a door and an opposite end coupled for rotation to an actuating device. When a power cylinder coupled to the operating member is activated, the actuating devices are rotated. This rotation causes the door supports to shift in opposite directions and to open the longitudinal doors.

A window arrangement for a rail vehicle includes a window pane disposed in a movable sliding frame and having at least one open position, a closed position and a transport position. The movable sliding frame is disposed in a window guiding frame, and the window pane has a larger surface than a corresponding window opening of the window guiding frame.

A door safety system (3) for a door (2), having a safety component (10) arranged on a movable door element (4, 4a, 4b) of the door (2) and a supply component (11) arranged on a stationary door frame (5) of the door (2) for supplying energy to the safety component (10). The safety component (10) has an electric energy store (12) which is designed to autonomously supply electric energy to the safety component (10) when the door (2) is open, and the safety component (10) and the supply component (11) are designed to electrically charge the electric energy store (12) of the safety component (10) when the door (2) is closed.

The present invention provides a system for automatic operation of a top hatch cover for a container, comprising a hatch cover, a cylinder mount, a main operating lever, a connecting link, and a hatch locking lever. The cylinder mount is configured for pivotally connecting a piston to the container. A lower portion of the main operating lever is connected to a cylinder rod of an air cylinder. A first extension of the connecting link is rotatably connected to an upper portion of the main operating lever and a second extension of the connecting link is coupled to the hatch cover. The main operating lever and the hatch locking lever are rotatably coupled to a main shaft mount, where the hatch locking lever is configured to pivot around the main shaft mount to move between a locked position and an unlocked position.

A door system includes a multi-panel door and a dual-synchronization drive assembly for the door system. The dual-synchronization drive assembly has a structural configuration and functionality that combines a drive mechanism with a synchronization mechanism. The dual-synchronization drive assembly transmits a drive force in a manner that causes linear movement of door panels of the multi-panel door system between an open position and a closed position. The dual-synchronization drive assembly causes a synchronized movement of the door panels at different linear speeds/velocities to fully advance the door panels to the open position or the closed position simultaneously. The dual-synchronization drive assembly includes a dual gear unit that is configurable to allow for any motion/speed ratio necessary in order to obtain a specific performance objective of the door system.

A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.

A hatch lock cover includes inner and outer flanges, with a keeper and a handle positioned between the flanges. The handle is rotatable with respect to the flanges to move a batten bar contacting surface into and out of engagement with a batten bar or a hatch cover tab of a hatch cover. A downwardly extending portion of an arm of the keeper may define an aperture and/or include a projection for securing an adjustment plate or extension piece to the arm to provide an alternative batten bar contacting surface. Alternatively, a mounting bracket may be provided to secure the hatch cover lock to a railcar, with the mounting bracket accommodating the hatch cover lock in different positions having different elevations. Such configurations allow the hatch cover lock to be adjusted for use with a batten bar or hatch cover tab having a gasket that has become worn out.

The invention relates to a double-leaf vehicle door device comprising at least the following: two door leaves, each of which can be moved between an open position and a closed position in the form of a respective end position and into any intermediate position between the first open position and the first closed position, wherein a first movement of the first door leaf between the first open position and the first closed position is carried out without mechanically coupling the first door leaf to the second door leaf in contrast to a second movement of the second door leaf between the second open position and the second closed position, and a common locking device is provided which locks the first door leaf in the closed position when the first door leaf is located in the closed position and which locks the second door leaf in the closed position when the second door leaf is in the closed position. A pre-locking function is provided such that of the first door and the second door leaf, the door leaf which first reaches the closed position is held in the closed position at least until the other door leaf has also reached the closed position, and the locking device is additionally designed to only then lock or become capable of locking the first door leaf and the second door leaf.

The present disclosure provides a hinge, a freight container that includes the hinge and a freight container that includes a locking rod and optionally the hinge. The hinge includes a locking pin, a first wing, a second wing and a first hinge pin that pivotally connects the first wing to the second wing. The hinge further includes a pair of hinge lugs each having a first set of surfaces defining openings through which a second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which a locking pin reversibly travels.

A flow rate adjusting device of the present invention includes a flow channel member and a valve mechanism. The valve mechanism includes a rod, a knob and a lock mechanism. The lock mechanism is switched by the knob moving in the traverse direction between a prohibited state in which the engaging portion is engaged with the to-be-engaged portion so that the rotation of the rod relative to the flow channel member is prohibited via the knob and a permitted state in which the engagement between the engaging portion and the to-be-engaged portion is undone so that the rod is permitted to rotate relative to the flow channel member.
