Abstract
A glyde-rail apparatus removably attached to a carrier such as an excavator to enable the excavator to mount and demount at any point along a railroad track and to travel along the railroad track without damaging the railroad track. A non-metallic cover attaches to the track of the excavator. A front swing arm assembly and a back swing arm assembly attach to ends of the excavator. A first pair of hydraulic cylinders on the front swing arm assembly and a second pair of hydraulic cylinders on the back swing arm assembly enable rail wheels to be raised or lowered. An operator of the carrier controls the raising and lowering of the front swing arm assembly and the back swing arm assembly from within a cab of the carrier by a combination of hydraulic controls in the carrier and the glyde-rail apparatus.
