Microcomputer controlled scaffold fastener testing machine

WDW-200 scaffold fastener universal testing machine is a classic and practical model developed by our company, and it is also the mainstream model currently produced.Through two new upgrades, design and development, the host structure and measurement and control system have been significantly upgraded, with a more reasonable structure and more complete functions. It is a new generation of electronic universal testing machine for steel pipe fasteners with leading technology in the industry.

This testing machine consists of four columns and two precision ball screws to fix the upper beam and work surface. It uses an AC servo motor and driver through a synchronous toothed belt to drive two pairs of high-precision, gap-free precision screws to move the middle beam up and down. It has the characteristics of reasonable structure, high rigidity, smooth loading, and good stability.The replacement of auxiliary tools can complete wheel buckles, steel pipe fasteners, bowl buckles, and plate buckle scaffolding at the same time., safety net, safety belt, safety ropeVarious mechanical property tests.
