Abstract
Various systems and methods for derailing a vehicle from a track are provided. In one embodiment, a device is provided that includes a directional derail block extending from a base and including a wheel deflecting surface arranged at an angle less than or equal to about 13 degrees with regard to a longitudinal axis of the track and designed to deflect the wheel away from the track. The length of the device is greater than or equal to about 53 centimeters (cm) (21 inches (in)).
Claims20
A device comprising:
- a first derail block extending from a base and including a wheel deflecting surface, the wheel deflecting surface configured to be arranged at a first angle with regard to a longitudinal axis of a track when the device is attached to the track and configured to deflect a wheel of a vehicle away from and off the track, the first angle less than or equal to about 13 degrees;
- and
- at least three clamping mechanisms positioned along the base and configured to engage with a rail of the track on a side of the track opposite the wheel deflecting surface and toward which the wheel is deflected by the wheel deflecting surface, with each of the at least three clamping mechanisms spaced apart from one another so as to enable forces to be dispersed as the wheel is deflected away from and off the track.
A derailing device comprising:
- a base;
- a directional derail block attached to the base and configured to deflect a wheel of a vehicle away from a track and including a wheel deflecting surface configured to be formed at a first angle with regard to a longitudinal axis of the track when the device is attached to the track, where the first angle is less than or equal to 13 degrees;
- a grab plate attached to the base and including a plurality of steps, each of the plurality steps having a rise greater than or equal to about 1 centimeter (cm) (0.4 inch (in)) and a run greater than or equal to about 2 cm (0.8 in);
- and
- a plurality of clamping mechanisms coupled to the base, where each of the plurality of clamping mechanisms includes a clamping arm and is configured to attach to the track.
