Computer Servo Hydraulic Horizontal Materials Testing Machine

Specially designed for tensile test of long materials like cable, electrical wire, deformed steel bar, steel rope, steel wire, steel chain, spring, webbing, nylon rope, shackle, hooks, cargo blocks…etc.

Besides servo hydraulic model the types of traditional hydraulic & manual control with the display by computer monitor or digital indicator can be selected as optional.

Moreover, either motor type or bench top type with horizontal design are available for special application.
