GRAVITATIONAL GRADER FOR ENDS OF BAR OBJECTS

摘要

The gravitational levelling machine consists of a frame (1) whose back end is adjusted to the connection with the tow rope (12) of the rope hoist. A supporting plate (2) is attached to the frame face at the front end of the frame (1). Also, at least one travel pulley (7) or, more advantageously, two travel pulleys (7) or, respectively, wheels are revolvingly mounted at the front end of the frame (1). They serve to prop up the frame (1) against a firm bottom (15). The frame (1) is tilted by the hoist so that its front end with the supporting plate (2) gets to a lower position than the back end and the bar-shaped objects (13) slip down towards the supporting plate and their ends become even (2).<IMAGE>
