RAILROAD CROSSING BLOCKING MACHINE

PURPOSE: To provide a railroad crossing gate machine for improving visibility of a crossing gate bar with respect to a regular size car and a large size car and reducing broken off accident of the gate bar. CONSTITUTION: A first crossing gate bar 2 and a second crossing gate bar 3 are attached to a body 1 and rotational action of lifting up and down are individually provided to them by a first rotational drive mechanism 11 and a second roatational drive mechanism and driven in such a way that difference of elevation is mutually caused at descent positions H1, H2. The first crossing gate bar 2 has the descent position H1 lower than the descent position H2 of the second crossing gate bar 3. The second crossing gate bar 3 has a first arm part 31 having its one end connected to the rotational drive mechanism. A second arm part 32 has its one end connected to the other end of a first arm part 31 by a joint part 33 and the second crossing gate bar 3 is bent at the joint part 33 in the descent position H2 to keep difference of elevation with respect to the first crossing gate bar 2.
