200 KN/ 20 Ton Hydraulic Tensile Testing Machine - HT-1010

Tensile Testing Machine

Brief Introduction of the fram:

Rigid four column / two-lead screw construction

Dual workspace design : upper for tensile test , lower for compression and bending tests

Movable lower crosshead providing exceptional easy operation

Accurate force measurement through precision load cell

With hydraulic wedge grips for easy change of inserts and specimen loading

Integrated displacement photoelectric encoder

Cylinder mounted at the bottom of the machine

Safeguard:

Overload protection: When the testing load is over 2%~5% of Max. Load, the system will unload.

Stroke protection: When the ram arrives at the upper limited position, the motor of oil pump will stop.

Max. Test load: 200KN

Load accuracy: ±1%
