A door leading edge sensor has a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and includes a cavity extending in a direction intersecting with the closing direction; a linear pressure sensitive sensor is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor has an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and has plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

This compartment of a railway vehicle defines an interior volume and comprises: a cover movable between an open position, in which the cover is offset from the interior volume, and a closed position, in which the cover covers the interior volume and at least partially delimits that interior volume, a bar, a central region of the bar extending out of the interior volume, and a hinge defining the path of the cover between open and closed positions.

The cover is rotatable about an axis of the bar between its open and closed positions, the bar forming a pin of the hinge.

A screw-driven control system includes a driving mechanism fixed in a cross beam, a guide locking piece and a limiting mechanism. The driving mechanism includes a screw rod and a motor driven nut assembly having a transmission frame, a nut sleeved in the screw rod, and a follow-up member fixed in the nut; the nut is mounted in the transmission frame, and the transmission frame is connected with a controlled object; the screw rod drives the nut assembly to reciprocate axially along the screw rod.

A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.

A door control device includes: an electric motor control unit configured to drive, in response to a closing command for closing a door that is driven to be opened and closed by an electric motor, the electric motor; a door closed state detection unit configured to detect a closed state of the door; and a lock command output unit configured to output a lock command to lock a locking device of the door, upon the closed state being detected when a predetermined waiting time has passed after the electric motor was driven by the electric motor control unit in response to the closing command and the closed state was detected by the door closed state detection unit.

A system for locking a platform screen door leaf, the leaf being capable of moving by a horizontal translational movement in a plane of the leaf between open and closed positions, including a bearing rail mounted on the leaf and having a reception recess, a motor body forming the stator of a drive motor of the leaf and mounted freely in rotation about a motor axis on a gear unit, a locking roller mounted projecting on the motor body and arranged so as to roll along the bearing rail during a movement of the leaf, and engage, by a rotation of the motor body, in the reception recess when the leaf reaches the closed position or the open position, in order to lock.

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. The locking rod is mounted to the door of the freight container, where the locking rod includes a cam that can move between a first predetermined position where the cam can engage the cam keeper and a second predetermined position where the cam is disengaged from the cam keeper and can travel past the end frame of the freight container and the cam keeper as the door travels into the volume of the freight container.

According to some embodiments, a discharge door locking system for a railcar discharge door comprises a lock piston configured to move between a first position (not engaged with an operating beam coupled to a discharge door) and a second position (engaged). The locking system comprises a first and second input. Activation of the first input moves the lock piston to the first position, and activation of the second input moves the lock piston to the second position. The first input of the locking system is coupled to a first input of an operating cylinder coupled to the operating beam. The first input of the operating cylinder is configured to move the discharge door to the open position.

At least one leaf of this door is equipped with a detection device comprising a mechanical detection device and a contactless sensor each capable of detecting a presence. The control circuit board comprises a control unit for movement of each leaf and a diagnostic unit, while means transfer, from the detection device in the direction of the diagnostic unit and the control unit, a first item of information representative of the activation state of the mechanical device, and a second item of information representative of the activation state of the contactless sensor. The diagnostic unit can identify a malfunction at least of the contactless detection device, when the first item of information has an active value while the second item of information has an inactive value. The invention allows redundancy to improve the availability of the detection device, while performing predictive maintenance for the operator, in particular a malfunction of the contactless sensor.
