Features
- Simple, quick, and precise installation;
- The design employs a torque-free approach to avoid the influence of factors such as friction, bolt torque, and bolt preload, ensuring that the bolts being fastened are subjected to pure tensile force.
- Especially suitable for fastening heavy-duty vibrating machinery;
- Equipped with a stroke indicator, allowing for observation, measurement, and control of the stretching amount during operation;
- Preload can be precisely set with an accuracy of up to ±3%;
