NPR-S Ratchet Pusher
The NPR-S is a ratchet pusher used to adjust the interval of frames when attaching side frames to the outer plating and the inner bottom plating of a ship.
For the NPR-S, when operating the handle, the length of this ratchet pusher gets longer because the screw built in the pipe is pushed out.
When attaching side frames of a ship, the NPR-S is convenient to be transported and simple to operate compared to HYD'JACK which makes it an efficient product
How to Use
EFor the NPR-S, after setting the ratchet pusher between work pieces to be pushed, push up or down the pawl according to purposes and then operate the handle.
Do not exceed the rated capacity specified on the pusher.
Be careful that there can be slipping when the inner side angsle of the both side work pieces to be pushed are not vertical or hozorintal.
For non-stopper types, leave at least 40mm of the screw thread inside one end of the pipe(80mm for both ends) when pulling the screw out of a pipe.
