- 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.
- 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.
- 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.
