Microcomputer controlled bolt tensile testing system (horizontal)

The microcomputer screen-display horizontal tensile testing machine is mainly used for static tensile strength test of high-strength bolts. At the same time, it can also be equipped with corresponding accessories to test the performance of anchors, clamps and connectors for prestressed tendons.  The hydraulic manual control technology is adopted to realize the loading, holding, unloading, pressurizing and reversing of the test process.  It can meet the requirements of GB228-200× "Metallic Tensile Test Method for Room Temperature Materials" and GB/T14370-2000 "Anchorage, Fixture and Connector for Prestressed Tendons" within a reasonable application range.

The horizontal space frame structure mainly consists of a base, front and rear crossbeams, a support cylinder, a guide, a special loading hollow oil cylinder, a special high-precision hollow sensor, a static tensile test device and the like. The front and rear crossbeams, the support cylinder, the static tensile test device and the loading oil cylinder form a closed loading space. The loading oil cylinder is installed on the front crossbeam of the main unit and is connected with the static tensile test device.  In addition, it is connected to the static tensile test device through the guide device, which can effectively ensure the coaxiality in the tensile test process and prevent the piston of the loading oil cylinder from rotating. 

It can specially order similar products of other specifications.
