ABSTRACT:
An improved rolling restraint device and method for restraining a person are disclosed. In a preferred embodiment, a lockable hinged frame that has a roller which is adapted for rolling on a surface of a structure is provided. Preferably, the structure to which the rolling restraint device is attached is a railroad rail. In certain embodiments, side rollers are also provided that permit the apparatus to continue to roll even in a tipped or tilted configuration. A tether is attached to an attachment point that is preferably disposed on top of the frame that surrounds the rolling restraint device. The tether is also attached to the person being restrained and thereby provides a safety device which may be moved along as the person moves along the track or work place.
