WAW-S Series Computerized PC Strand Tensile Testing Machine

(600kN, 1000kN Capacity, 6 columns, 0.5 class accuracy)

 

1. Introduction

This WAW-S series computer control servo hydraulic universal testing machine is designed for tensile strength test Rm, measuring non-proportional extension Rp0.2, etc of PC strand (prestress steel strand).

It uses high precision load cell to measure testing force, high precision encoder to measure displacement and extensometer to measure deformation of PC strand.  

It adopts professional hydraulic operated tensile grip, easy and quickly grip the sample. The successful testing ratio can reach to 100%, the sample is broken at the middle position. Not only it improves the successful testing ratio, it also saves time and testing cost. It’s an ideal testing machine for PC strand manufacturer, quality inspect bureau, college and university, etc.

The machine is calibrated according to ISO 75001 and ASTM E4. In testing standard, it conforms to ISO6934, ISO6892, etc international testing standards.

3. Professional tensile jaw:

Four pieces of tensile jaws are inserted into the tensile grip seat, then it adopts hydraulic operated the clamping and loosen of PC stand. The good quality tensile jaws are endurable, long life. It can tighten holding the sample without any loosen or slippage during the test. The well adjusted clamping force can not make the sample broken at the ends of clamping, it would break at the middle position of the smple.
