[Application]

  • 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 hsip.

[Features]

  • When operating the handle, the length of the NPR-A ratchet pusher gets longer as the pipe comes out by the functioning of the screw.
  • NPR-A is an efficient ratchet pusher which is lighter and easier to be transported and simpler to operate than the existing HYD'JACK.
  • The stopper type has the built-in pin to prevent the screw from completely coming out of a pipe.

[How to use]

  • After fixing the ratchet pusher between a tack welded frame(L- and T-section steel)  and a frame to be tack welded, push up or down the pawl according to purposes and then operate the handle.

[Warnings]

  • 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 and the frame is more or less than 90°.
  • 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 ouot f a pipe.

[Application]

  • The NPR-B is a ratchet pusher to push outwards work pieces whose height is low and interval is short.
  • The NPR-C 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-B is a special ratchet pusher which has one screw built in the pipe and the other screw in the screw inside the pipe.
  • The NPR-B is designed to be lightweight, so it is convenient tobe transported, and also easy to work with in small space.
  • For the NPR-C, the two pads, which come in contact with a work piece,  are built in the bearing and the tooth-shaped contact area enables the rotation and the tilting(max. 13°) of the pads to be free  and also to prevent slipping, making the NPR-C a safe product.
  • The stopper type has the built-in pin to prevent the screw from completely coming out of the pipe.

[How to use]

  • After fixing the ratchet pusher between work pieces to be pulled(the NPR-B) and erecting the swivel pad vertically(the NPR-C),  push up or down the pawl according to purposes and then opearte the handle.

[Warnings]

  • Do not exceed the rated capacity specified on the ratchet puller.
  • Be careful that there can be slipping when the inner angle of a work piece to be pushed is 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.

[Application]

  • 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]

  • 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 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.

NPR-KB

WLL(TON) Working Length A ØB C D Weight(kg)
1 380-560 380 37 395 108 5.9

[Application]

  • 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

[Features]

  • 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.

[Warnings]

  • 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°.
