Abstract

See full text

A method for replacing a damaged brake beam on a railcar having a car body supported on a railcar truck. The railcar truck includes a wheel and axle assembly mounted between a pair of laterally spaced side frames. The side frames include structure, on an inboard side thereof, for guiding and supporting the brake beam, and with the structure on the side frame members defining a predetermined lateral distance therebetween. The method comprises the steps of: removing the damaged brake beam from between the side frames of the railcar truck; arranging a first part of a replacement brake beam structure into supported and guided relation with the brake beam guide on the first side frame, with the first part of the brake beam structure having an operative length shorter than the predetermined distance between the brake beam guides on the first and second side frames; arranging a second part of the replacement brake beam structure into supported and guided relation with the brake beam guide on the second of the side frames, with the second part of the brake beam structure having an operative length shorter than the predetermined distance between the brake beam guides on the first and second side frames; securing the first and second parts of the replacement brake beam structure to each other to form a rigid assembly capable of withstanding the braking forces applied thereto during operation of the railcar and with the combined operative lengths of the first and second parts of the replacement brake beam structure being substantially equivalent to the predetermined distance between the brake beam guides on the first and second side frames; and providing a brake head in operable combination with each of the first and second parts of the replacement brake beam structure for movements toward and away from the wheels as the first and second parts forming the rigid assembly move within the brake beam guides on the side frames.
