Abstract
An adzer skid assembly having a frame and a base plate attached to the frame. The base plate has an adzer unit attached thereto. The frame has a receptacle for slidably attaching the frame to a railroad track maintenance machine so that up and down motion of the railroad track maintenance machine does not produce up and down motion of the adzer skid assembly. Hydraulic cylinders are attached to the baseplate and are attached to skids, wherein the hydraulic cylinders raise and lower the skids relative to the frame and baseplate and determine the cutting depth of the adzer unit. During the adze cutting process the adzer unit is supported entirely by the skids as the skids move across railroad crossties.
Claims9
An adzer skid assembly, comprising:
- a) a frame and a base plate attached to said frame, said base plate providing attachment of an adzer unit;
- b) a receptacle on said frame for attachment of said frame to a railroad track maintenance machine;
- and
- c) hydraulic cylinders attached to said frame or base plate and attached to skids, wherein said hydraulic cylinders raise and lower said skids relative to said frame and said base plate.
An adzer skid assembly, comprising:
- a) a frame and a base plate attached to said frame, said base plate providing attachment of an adzer unit;
- b) a receptacle on said frame for attachment of said frame to a railroad track maintenance machine;
- c) hydraulic cylinders attached rotatably to said frame or base plate and attached rotatably to skids by means of a linkage system, wherein said hydraulic cylinders raise and lower said skids relative to said frame and said base plate;
- and
- d) an electronic speed control system that automatically adjusts the forward speed of the railroad track maintenance machine relative to the rotational speed of a motor that drives an adzer unit, so that a decrease in rotational speed of the motor will cause a decrease in the forward speed of the railroad track maintenance machine, and an increase in rotational speed of the motor will increase the speed of the railroad track maintenance machine up to a desired endpoint.
