Civil engineering & Material Testing equipments

Intelligent Prestress tensioning equipment


Model: ZL-5


The prestress tensioning equipment is mainly used for pre-stressing the rods and cables that used in civil engineering construction, full automatic testing of load and elongation, higher prestress control with servo pump technology, whole process full automatic control.


  • Higher control accuracy of prestress with latest digital valve technology
  • Timely checking the elongation of cables and reach automatic control
  • Regularized tensioning process, less prestress loss, the whole tensioning process reaches intelligent control
  • Easy & friendly operation interface, good human-machine interactive function, no high requirement for operator
  • Wireless communication between controller and computer, no need cables, easy moving at site
  • Automatic test report generation, customized report formation, higher working efficiency.
