User configurable horizontal brake feature for railroad crossing gates

1. A method of controlling a crossing gate comprising:

determining if a first crossing gate arm is in a substantially horizontal position; and

locking the first crossing gate arm in the substantially horizontal position by activating a braking mechanism when it is determined that the first crossing gate arm is in the substantially horizontal position, the braking mechanism preventing the first crossing gate arm from being raised while the braking mechanism is activated,

wherein the step of determining if the first crossing gate arm is in the substantially horizontal position comprises:

monitoring an output of a sensor connected to the first crossing gate arm; and

determining if a value of the sensor output is indicative of the first crossing gate arm being in the substantially horizontal position,

wherein the crossing gate further comprises a second crossing gate arm and said step of locking the first crossing gate arm in the substantially horizontal position simultaneously locks the second crossing gate arm in the substantially horizontal position.

2. The method of claim 1 , wherein the braking mechanism is connected to a first crossing gate support arm connected to the first crossing gate arm.

3. The method of claim 1 , wherein the sensor is a gate tip sensor.

4. A railroad crossing gate comprising:

a first crossing gate arm connected to a first crossing gate support arm; and

a gate mechanism connected to the first crossing gate support arm and for raising and lowering the first crossing gate support arm and the first crossing gate arm, said gate mechanism comprising a braking mechanism connected to the first crossing gate support arm and

a controller, said controller adapted to:

determine if the first crossing gate arm is in a substantially horizontal position, and

lock the first crossing gate arm in the substantially horizontal position by activating the braking mechanism when it is determined that the first crossing gate arm is in the substantially horizontal position, the braking mechanism preventing the first crossing gate arm from being raised while the braking mechanism is activated,

wherein said gate mechanism comprises a horizontal position detector connected between a shaft used to raise and lower the first crossing gate support arm and the controller, the controller being adapted to determine if the first crossing gate arm is in the substantially horizontal position by:

monitoring an output of the horizontal position detector; and

determining if a value of the horizontal position detector output is indicative of the first crossing gate arm being in the substantially horizontal position,

wherein the railroad crossing gate further comprises a second crossing gate arm supported by a second crossing gate support arm, the second crossing gate support arm being connected to the gate mechanism, wherein the controller is adapted to lock the first crossing gate arm and the second crossing gate arm simultaneously.

5. The railroad crossing gate of claim 4 , wherein the horizontal position detector comprises:

a cam mechanism connected to the shaft; and

an electrical contact connected to the controller, the contact being adapted to open and close when contacted by the cam mechanism.

6. The railroad crossing gate of claim 5 , wherein the controller is adapted to monitor the output of the horizontal position detector by determining if the contact is open or closed.

7. The railroad crossing gate of claim 4 , wherein the controller is further adapted to:

initiate a timer after determining that the value of the horizontal position detector output is indicative of the first crossing gate arm being in the substantially horizontal position; and

wait for the timer to expire before locking the first crossing gate arm in the substantially horizontal position.

8. The railroad crossing gate of claim 4 , further comprising a switching mechanism connected to the controller and being adapted to output a first value in a first position and a second value in a second position, said controller being further adapted to lock the first crossing gate arm in the substantially horizontal position if it is determined that the first crossing gate arm is in the substantially horizontal position and the switching mechanism output has the first value, but not the second value.

9. A control system for a crossing gate, said system comprising:

a horizontal position detector adapted to output a first value when a first crossing gate arm is in a horizontal position and a second value if the first crossing gate arm is not in the horizontal position;

a holding mechanism being activated to hold a first crossing gate support arm connected to the first crossing gate arm in a locked position upon receipt of a control signal, the holding mechanism preventing the first crossing gate arm from being raised while the holding mechanism is activated; and

a controller adapted to monitor the output of the horizontal position detector and to send the control signal to the holding mechanism when the output has the first value,

wherein the holding mechanism is activated to hold a second crossing gate arm connected to a second crossing gate arm in the locked position upon receipt of a control signal, wherein the controller is adapted to lock the first crossing gate arm and the second crossing gate arm simultaneously.

10. The system of claim 9 , wherein the horizontal position detector comprises a gate tip sensor connected to the first crossing gate arm.

11. The system of claim 9 , wherein the horizontal position detector comprises:

a cam mechanism connected to a shaft connected to the first crossing gate support arm; and

an electrical contact electrically connected to the controller, the contact being adapted to open and close when contacted by the cam mechanism, the first value corresponding to the closed contact and the second value corresponding to the opened contact.

12. The system of claim 11 , further comprising a timer, wherein the controller is adapted to initiate the timer and wait for the timer to expire before sending the control signal to the holding mechanism.

13. The system of claim 9 , further comprising a switching mechanism outputting a first switch value when the holding of the first and second crossing gate arms is desired and a second switch value when the holding of the first and second crossing gate arms is not desired, and wherein the controller is adapted to send the control signal only if the switching mechanism outputs the first switch value and the horizontal position detector output comprises the first value.

14. The system of claim 9 , further comprising at least one device connected to the controller and being adapted to output the horizontal detector output.
