A rail tie plate retaining workhead is provided for use in conjunction with a rail tie replacement machine moving along a railroad track having a pair of rails. The workhead includes a workhead frame configured for movement along the track relative to the rail tie replacement machine, and a pair of plate retaining frames, each frame associated with a respective one of the rails, and being connected to the workhead frame. Each plate retaining frame has at least one rail guide wheel connected to the retaining frame using a fluid powered cylinder, the wheels vertically reciprocating between an extended position, in which the workhead is raised to a travel position, and a retracted position, in which the workhead is lowered to a working position in operational relationship with at least one targeted rail tie plate.

A rail plate handling device is provided for removing and reinstalling rail tie plates located on rail ties on a railroad track, includes a frame configured for movement relative to the track, at least one tie plate gripping assembly mounted to the frame, the assembly configured for grasping a selected tie plate at the front and rear edges between an adjacent one of the at least one raised rail raised from the operational position supported by the selected tie plate and the associated tie in the operational position upon which the plate was resting, each gripping assembly including a pair of opposing gripping jaws which are configured for controlled reciprocation in a direction parallel to the rails along a guide bar, the guide bar being slidable with the gripping jaws and the selected plate, relative to the frame.

A regulator moldboard and grader blade assembly 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.

Roadworthy rail ballast regulator

A rail fastener orienter is provided for orienting rail fasteners to a desired orientation, the fasteners having a head, an opposite tip and a shank connecting the head to the tip, and being sequentially provided to the orienter in one of a head right, head left, head up and head down orientation. The orienter includes a frame having an upper end and an opposite lower end, and defining a track with an inlet adjacent the upper end, and an outlet adjacent the lower end, the track dimensioned for slidingly and rotatingly accommodating the shank. At least one stage holder is provided for accommodating the fastener in the track as the head is at least partially engaged by at least one bumper for repositioning to a desired one of the orientations, such that the fastener reaches the outlet in the desired orientation after axial rotation.

An automatic rail spike feeder system for use with a rail maintenance vehicle having a bulk storage bin for containing a supply of spikes, and at least one spike driving mechanism, includes a mechanism constructed and arranged for receiving a supply of spikes from the storage bin and for automatically delivering individual spikes to the at least one spike driving mechanism in a desired orientation without operator contact with the spikes.

A die assembly adapted to be attached to one of a wrench first arm and a wrench second arm. The die assembly includes a die having a pipe facing front spaced apart from but parallel to the pipe longitudinal axis, a wrench facing rear, and two spaced apart opposed sides, each connected to the die front and die rear. The die is thick on one side and thin on the other side so that the die facing front has a face that recedes from the pipe from one edge to the other edge so that contact between the die facing front varies depending upon the diameter of the pipe. The die rear also has a convex curve so that the die has a thick mid section.

A drill comprising a frame supported for movement over the ground in a forward propel direction and a rearward propel direction, a mast mounted on the frame in a generally vertical position, and a drill head moveable up and down the mast. The drill head is selectively engageable with the upper end of a drill pipe so that the drill pipe is raised and lowered out of and into the ground when the drill head moves up and down the mast. The drill further includes a crawler drive for moving the drill in the forward propel direction, a motor for moving the drill head to cause drilling, and an operator's cab positioned on the frame adjacent the mast. The cab includes a first console and a second console spaced from the first console, controls on the first console for operating the forward propel drive, and controls on the second console for operating the drill head motor.

A roller is designed for adaptation into a blasthole drill and is specifically designed for use in conjunction with a rotary carriage to allow the carriage to move up and down a blasthole drill mast as needed. The roller is made of a substantially non-deformable material combined with a deformable material. Under light loads, the deformable material contacts and supports the load to provide enhanced operation of the roller. Under heavy loads, the deformable material advantageously deforms to a point which allows the substantially non-deformable material and deformable material to contact and cooperatively support the load.
