Nagaki Seiki Haru Wire Tensioner

Manufacturer: Nagaki Seiki Co., Ltd.
Our lineup is extensive, ranging from wire tensioners that can be used for a wide range of applications from low to high tension, to belt tensioners that use fiber belts, and chain tensioners that are popular for strong tensioning work.
Precautions regarding product handling
◇ Always use the tensioner horizontally. Do not use it vertically, as it is dangerous.
◇ Replace the wire immediately if any strands break or kinks form.
◇ Always leave at least one turn of wire or belt remaining when performing tensioning work.
◇ If tension is released from the tensioner due to other factors while tension is applied, the brake may remain engaged in the pull-out (return) direction, preventing the handle from turning. In this case, reapply tension and use the rebound to return the handle to release the brake.
◇ When winding up, if you set the switch to “return” and wind in the reverse direction, the screw on the butterfly washer will break, so wind it correctly.
