An automatic wheel chock assembly for parking a trailer includes a trailer that has a plurality of axles, a frame and air brakes. Each of the axles has a wheel that is rotatably coupled thereto. A chock unit is rotatably coupled to the trailer and the chock unit is operationally coupled to the air brakes. The chock unit is actuated into a deployed position when the air brakes are turned on. Thus, the chock unit lowers a stop between the wheel on each of a respective pair of the axles for inhibiting the trailer from rolling. The chock unit is actuated into a stored position when the air brakes are turned off thereby facilitating the wheel on each of the respective pair of axles to roll.

The present invention relates to a test bench for a switch machine of a railway switch, the test bench comprising: a rigid frame adapted to receive the switch machine, the switch machine comprising a switch motor adapted to move a driving shaft; a pair of outer rails fixed to the frame, wherein the switch machine is adapted to be fixed to the outer rails; a pair of inner rails, which are movable with respect to the outer rails between a first end position and a second end position, the inner rails being adapted to be connected to the driving shaft of the switch machine; a braking module connected to the pair of inner rails, the braking module is adapted to generate a braking force that brakes the movement of the inner rails.

A turnout includes a fixed beam, and a first and a second movable beams respectively on two opposite sides of the fixed beam. The fixed beam is arranged on a turnout platform. The first movable beam is movably arranged on the turnout platform between a first and a second positions. The second movable beam is movably arranged on the turnout platform between a third and a fourth positions. When the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage; when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage.

A turnout apparatus for an overhead monorail includes a frame, an input fixed rail docking an input rail, output fixed rails each docking an output rail, and movable rails disposed between the input fixed rail and the output fixed rails. The input fixed rail is disposed at one end of the frame. The output fixed rails include a first output fixed rail and a second output fixed rail disposed at the other end of the frame. The movable rails include a first movable rail docking the input fixed rail and the first output fixed rail, and a second movable rail docking the input fixed rail and the second output fixed rail. The first and second movable rails are fixed and rotatable about a horizontal line as an axis. Directions toward which upper rail surfaces of the first movable rail and the second movable rail face differ by 180 degrees.

A railroad switch device for moving railroad switch points. The device includes a hydraulic unit having a hydraulic manifold coupled to a hydraulic pump integrated with an electric motor via a pressure pipe, where the hydraulic manifold is also coupled to the hydraulic pump via a hydraulic oil reservoir and a return pipe, and the hydraulic manifold is coupled to a hydraulic double-rod cylinder to provide forward movement and reverse movement of a point rod. Also included is a mechanical target to automatically indicate the position of a point rod, and a plurality of spring units to produce a continuous thrust force for holding the railroad switch points closed in forward position and reverse position, wherein the plurality of spring units control the target rotation to 90 degrees.
