Abstract:
An attachment used in conjunction with a backhoe or track hoe to convert it into a machine to unload ties off of railroad cars. Two pins on an upper end of the attachment secure it to the distal end of the working arm of the backhoe or track hoe so that a front edge of the attachment point toward the backhoe or track hoe. Upper ends of four c-shaped members attached to an upper plate on the upper end of the attachment. Opposite lower ends of each of the four spaced apart c-shaped members are flattened on upper and lower surfaces into a point. A lower plate is secured to the upper surfaces of the lower ends of the c-shaped members to form the front edge. Support bars secure between adjacent c-shaped members and openings are provided in the c-shaped members to reduce weight while maintaining strength.
