Abstract
A cutting apparatus for cutting a rail or other elongated workpiece includes a rotatable blade for cutting the rail, a blade cover for covering the blade, an engine (or motor) for driving the blade, and a frame for supporting the blade, the blade cover and the driver. The cutting apparatus further includes link mechanisms. One link mechanism supports the blade and the blade cover relative to the frame and permits the blade cover to move while maintaining a predetermined attitude during cutting. Therefore, the blade cover moves vertically and avoids hitting obstacles. Another link mechanism moves the driver while maintaining a predetermined attitude of the driver. Therefore, the driver remains level during cutting.
