NPR-C Ratchet Pusher
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.
For the NPR-C, the two pads, which come in contact with a work piece, are built in the bearing and the toothshaped 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
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
