詳細信息

簡單、快捷、精確

Simple, quick and accurate

采用無轉(zhuǎn)矩設(shè)計,避免摩擦、螺栓扭曲、螺栓預(yù)緊力等因素的影響,使被緊固螺栓受純拉伸力。

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.

特別適合重負荷震動機械緊固。

Especially suitable for heavy load vibration machinery fastening.

帶有行程指示器,允許在操作過程中觀察、測量和控制拉伸量

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

可以精確設(shè)定預(yù)載荷,精度高達 ±3%

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

最大工作壓力:150MPa

Maximum working pressure: 150MPa
