· Application
- The NPR-H is a manual screw pusher used for fixing or pushing lightweight steel blocks.
- 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.
· Features
- The NPR-H is a simple and lightweight pusher with no handle and ratchet pusher.
- The center of the NPR-H is in the shape of hexagon so that a spanner can be used when dismantling is impossible due to the load caused
by an external force after completing work.
- 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
- For 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.
· Warnings
- Do not exceed the rated capacity specified on the pusher.
- Be careful that there can be slipping when the inner side angles of the both side work pieces to be pushed are not vertical or horizontal.
- 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.
