Load Frame
According to load capacity and test application, the load frames are available in single column, table and floor type to meet different test applications.

Single column machine is more suitable for bio-medical, textiles, plastic film industries where load testing requires a lower capacity. Dual-column table type is the main choice for rubber, plastic, composites and metal sectors where the specimen needs a wide test area and middle strength. Floor type is the optimal units for most demanding applications of metal, alloys, and fasteners, whose specimen needs a high capacity of size and strength.

The frames all take human factors into considerations in the design to ensure the safety, reduce operators’ fatigue and provide the highest flexibility. The extremely robust cross-head guidance is incorporated in all frame designs so as to provide the highest stiffness of lateral cross-heads.

With gap-less load frames, the testing system imports larger capacity servo motor, stable driving system and advanced control system and can complete the low cycle fatigue test like square and trapezoidal waveform under 0.5 Hz.
