Rope Grips

• Tensile force reduction through multiple looping
• Tensile force reduction through single looping and knotting
• Specimen insertion requires little effort
• Self-gripping of specimen eliminates additional gripping via threads or pneumatic actuator This specimen grip is a cost-efficient solution for testing requirements.

The rope grip can be used to grip 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 by the load reduction roller's grooves when wrapped.

• Tensile force reduction via single or multiple looping
• Interchangeable load reduction rollers for a perfect fit with specimen material
• Various jaw inserts are available for different specimen materials and diameters
• Quick, easy specimen insertion
• Automatic centering of specimen via guide grooves

The rope grip can be used to grip tensile specimens.

The closing force is generated via looping and additional screw end clamping. The specimen loops around the load reduction roller once or multiple times. The specimen's tensile stress is largely reduced via frictional contact. The end of the specimen is gripped via integrated screw end clamping.

The specimen is automatically centered by the load reduction roller's grooves when wrapped.

• Tensile force reduction via single or multiple looping
• The closing force is applied via a mechanical threaded connection with a very high ratio. Very high closing forces are achieved with at least 2.5 times the maximum nominal load with normal specimen grip pulling
• Specimen treatment such as end-coating is eliminated due to high closing forces
• Interchangeable load reduction rollers for a perfect fit with specimen material. Large roller diameter for rigid ropes (wires, wire ropes), small roller diameter for flexible ropes (natural fiber ropes, plastic ropes)
• Various jaw inserts are available for different specimen materials and diameter ranges
• Easy specimen insertion makes these grips suitable for series testing
• Automatic centering of specimen via guide grooves

The rope grip can be used to grip 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 specimen is automatically centered by the load reduction roller's grooves when wrapped.

• Tensile force reduction via single or multiple looping.
• 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 grip can be used to grip tensile specimens.

The specimen grip contains load reduction rollers and mechanical wedge end clamping.

The closing force is generated via looping and additional screw end clamping. The specimen loops around the load reduction roller once or multiple times. The specimen's tensile stress is largely reduced via frictional contact. The end of the specimen is gripped via integrated wedge end clamping.

• 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 grip can be used to grip tensile specimens.

The specimen grip is modularly mounted, thereby optimally adjusting to the specimen material.

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

The specimen is ergonomically and material sparingly wrapped around the load reduction rollers,

The specimen's tensile stress is largely reduced via frictional contact on the load reduction roller. The substantial roller depth accommodates up to four loops. The remaining residual force is absorbed by means of hydraulic end clamping, enabling jaw breaks to be avoided completely.
