A ratchet pusher to use in assembling thin steel keel blocks in ship assembly shops. The NPR-KB is for adjusting horizontality of the inner plating arranged on a flat plate(worktable) or adjusting the interval of frames
- One worker alone can quickly and accurately perform the horizontal and vertical work due to the magnetic force of the magnet attached to the one end part of the pusher.
- The stopper type has the built-in pin to prevent the screw from completely coming out of the pipe.
How to use
After setting the ratchet pusher between frames to be tack welded and tack welded frames(L- and T- sections), operate the handle.
- Do not exceed the rated capacity specified on the ratchet pusher.
- Be careful that the pusher can slip when the erected angle of the inner plating or the frame is more or less than 90°.
