Load Frame
According to load capacity & test application, the load frames are available in single column, table and floor type to meet a variety of 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.

Load cell is with high accuracy and interchangeable for all frames. Each frame is allowed to operate in full capacity.

High accuracy:

The preloaded precision ball-screw with high speed & low noise ensures high speed and accuracy of position measurement and less noise.

High stiffness:

The load frame is with dual columns or four columns , and heavy duty pre-loaded bearings.

Safety features:

The testing machine stops automatically when the change in the test force exceeds a specified value during operation.

Large space in the working area:

The insides of columns provide wide space for the operator.

Over-stroke limiter:

The range of the cross-head movement is mechanically limited.

Comfortable working area:

The wide legroom under the load unit provides a comfortable working area for attaching and removing jigs.
