20100293819 | ROTARY UNDERCUTTER FOR RAIL LINE MAINTENANCE - A railroad ballast removal system capable of removing ballast material from below a rail line. The railroad ballast removal system includes at least one rotary cutting wheel having a plurality of individually replaceable cutting attachments positioned about a perimeter of the rotary cutting wheel. Each rotary cutting wheel is attached to an articulated arm capable of adjusting the position of the rotary cutting wheel along varying axis. The articulated arm is mounted to a support structure capable of transporting the rotary cutting wheel to a portion of railway requiring maintenance of the ballast material. The railroad ballast removal system is able to operate at a spot location or in a continuous manner down a length of railroad track. The ability to manipulate the rotary cutting wheel along the various axis allows the rotary cutting wheel to be used for ballast removal in locations wherein adjacent railways limit cutting access. | 11-25-2010 |

20120216433 | METHOD FOR PUTTING INTO OPERATION A CLEARING APPARATUS SUITABLE FOR PICKING UP BALLAST AND CLEARING APPARATUS - A method puts into operation a clearing apparatus suitable for picking up ballast and is disposed in an endless configuration during employment so as to encircle a railroad track. The clearing apparatus has a horizontal cross-duct which, prior to a start of the employment, is intended to be positioned below the railroad track and connected, on the one hand, to a rising duct and, on the other hand, to a return duct of the clearing apparatus. The method includes displacing ties of the railroad track in a longitudinal direction of the railroad track to create a tie gap; lowering the cross-duct through the tie gap between two rails of the railroad track and transferred, below the ties, into a working position extending crosswise to the longitudinal direction of the railroad track; and connecting the cross-duct to the rising duct and to the return duct. | 08-30-2012 |
20130192095 | Undercutter self adjusting and shock absorbing device - A self adjusting chain mechanism for use with an undercutter attached to an excavator having hydraulic means for adjusting the undercutter; the self adjusting mechanism has a chain and sprocket assembly in a sprocket holding frame, a ram and piston, all operating in conjunction with the hydraulics of the excavator with a control system to move an adjuster shaft connected to the chain sprocket assembly, so as to cause the chain to tighten in response to the changes in hydraulic pressure. | 08-01-2013 |
20140360056 | Railcar Ballast Distributing Apparatus - This invention may comprise a railcar ballast distributing apparatus comprising a ballast railcar traveling in a direction of travel on a pair of railroad rails, a plow mechanism operatively attaching to a main bracket assembly attaching to the middle underside of the railcar, and being powered by a hydraulic system, the plow mechanism comprising: a spring box assembly mechanism operating a single plow blade assembly comprising: a pair of articulating and independently movable plow blades vertically and independently adaptable during contact against the pair of railroad rails and having a transport mode span and a separate deployed mode span, and a spring-loaded safety locking latch mechanism, the spring box assembly mechanism vertically deploying and retracting the pair of plow blades, which automatically and differentially change orientation when contacting the pair of railroad rails, and increase to the deployed mode span and decrease to the transport mode span. | 12-11-2014 |

20160083913 | SEGMENTED RAILWAY REGULATOR BLADE - A blade segment is provided for use on a railway regulator wing, and includes a blade body having a front surface, a top surface, a bottom surface, a first side edge and a second side edge, the blade body having at least one mounting aperture. Each of the first and second side edges having an irregular configuration such that adjacent segments tightly and nestingly engage each other along complementary side edges as they are mounted upon the railway regulator wing. | 03-24-2016 |
20160108582 | ROADWORTHY RAIL BALLAST REGULATOR - A regulator moldboard and grader blade assembly is provided and includes a moldboard having at least one transversely extending pin, the pin having a notch with a surface inclined toward the moldboard. At least one grader blade has at least one mounting opening having a flared surface complementary to the notch so that the blade is hangable on the pin so that the notch draws the blade against the moldboard as a fastener tightens the blade to the moldboard. | 04-21-2016 |
