What is the advantage of a crimper ПКВк-16т? There is a metal cylinder on the tool? What is it used for?

Even visually you can note that this tool has a different design. The main advantage of this crimper is the possibility to crimp a terminal with the dies located at the butt end of the tool. It is perfect for crimping a cable with a very short tail. The tool also has an integrated crimping force adjustment wheel. This helps to choose a correct force for good results especially when you deal with big cross-sections from 6 to 16 mm². The metal cylinder covers a special spring that helps to adjust the opening of jaws and set the necessary crimping force of the tool in accordance with the cross-sections. That is why we recommend not opening or trying to rotate it. Without this adjustment wheel, the tool will not work.
