Rope Grips

• Looping the specimen around the load reduction roller ensures gentle clamping without jaw breaks.

• These grips represent a cost-effective solution. Looping and knotting the specimen eliminates the need for an end-clamping device.

The rope grips can be used for testing dimensionally unstable tensile specimens.

The closing force is generated via rope friction and knotting or wrapping. The specimen's tensile stress is largely reduced via friction on the load reduction roller.

The specimen is automatically centered on insertion by the predetermined groove in the load reduction roller.

• Looping the specimen around the load reduction roller ensures gentle clamping without jaw breaks.

• Fast, easy insertion and centering of the specimen is made possible by a guide groove in the load reduction roller.

• Interchangeable load reduction rollers enable optimum adaptation of the specimen grips to accommodate different specimen materials.

• If the application changes the jaws can be changed over quickly and easily - no tools required. The jaws are centered automatically.

The rope grips can be used for testing dimensionally unstable tensile specimens.

The specimen is passed around the load reduction roller one or more times. The resulting frictional force reduces the tensile stress before the screw clamp at the end of the specimen to the extent that jaw breaks are avoided.

• If the application changes the jaws can be changed over quickly and easily - no tools required. The jaws are centered automatically.

• The hydraulic clamping ensures precisely defined, reproducible gripping pressure.

• High gripping forces ensure secure clamping of the specimen. The need for specimen pre-treatment such as coating the ends is eliminated.

The rope grips can be used for testing dimensionally unstable tensile specimens.

The carrier plate, load reduction rollers, end clamping and jaws are compiled.

The specimen is ergonomically and material sparingly wrapped around the load reduction rollers, only touching the ends of the specimen materials. This type of wrapping is particularly suited for very sensitive surfaces.

The specimen's tensile stress is largely reduced via frictional contact on the load reduction roller. Specimen ends are mechanically gripped via a screw end clamping (with force amplification if required) or hydraulic clamping element.

The rope grips can be used for testing dimensionally unstable tensile specimens.

The specimen is wound around the load reduction roller once or several times. The resulting frictional force reduces the tensile stress before the wedge clamping at the end of the specimen to such an extent that jaw breaks are avoided.

• Tensile force reduction via single or multiple looping.
• Optimal clamping via precisely defined and reproducible clamping pressure.
• Hydraulic end-clamping enables high closing force, thereby eliminating specimen treatment such as end-coating.
• Interchangeable load reduction rollers for optimum matching to specimen material.
• Various jaw inserts are available for different specimen materials and diameter ranges.
• Quick specimen insertion makes these grips suitable for series testing.

The rope grips can be used for testing dimensionally unstable tensile specimens.

• Large roller diameter for stiff ropes (wires, steel ropes)
• Small roller diameter for flexible ropes (natural fiber, plastic ropes).

Three different load reduction rollers are available together with various jaw inserts.

The specimen is passed around the load reduction roller one or more times. The resulting frictional force reduces the tensile stress before the hydraulic clamp at the end of the rope sufficiently to avoid jaw breaks.
