简单、快捷、精确

Simple, quick and accurate

采用无转矩设计，避免摩擦、螺栓扭曲、螺栓预紧力等因素的影响，使被紧固螺栓受纯拉伸力。

The non-torque design is adopted to avoid the influence of friction, bolt twist and bolt pre-tightening force, so that the fastened bolt is subjected to pure tensile force.

特别适合重负荷震动机械紧固。

Especially suitable for heavy load vibration machinery fastening.

带有行程指示器，允许在操作过程中观察、测量和控制拉伸量

With stroke indicator, it is allowed to observe, measure and control drawing amount during operation.

可以精确设定预载荷，精度高达 ±3%

The pre load can be accurately set, and the accuracy is as high as ± 3%.

最大工作压力：150MPa

Maximum working pressure: 150MPa
