This product is a professional tool that uses hydraulic power to accurately stretch bolts to produce controllable preload, and uses gravity reset. The hydraulic system is used to apply axial tension to the bolts to elastically stretch them, and then the position is locked by tightening the nuts, thereby ensuring uniform preload and long-term stability of the bolt connection. It is widely used in high-precision, high-load industrial scenarios.
