Rope Grips

Tensile stress on the specimen is reduced via frictional contact with the load reduction roller. The ends are clamped mechanically via a screw (with force amplification if required), a wedge, or a hydraulic gripping unit.

Key Advantages and Features

  • Maximum test load: 2.5 to 100 kN
  • Tensile force reduction via single or multiple looping
  • Interchangeable load reduction rollers for a perfect fit with specimen material
  • Quick, easy specimen insertion requires little effort, making these grips suitable for series testing

Rope Grips

Fmax 2.5 kN

Advantages and features

  • 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.

Function description

Sarmal çene, çekme numunelerin sıkıştırılmasında kullanılabilinir.

Kapatma kuvveti sürtünmesi ve düğümleme veya sargı ile uygulanır. Numunenin çekme gerilmesi, kuvvet düşürücü makaralara sürtünmesi yoluyla azaltılmaktadır.

Numune, etrafında sarılırken makarasındaki önceden belirlenmiş oluklar tarafından otomatik olarak ortalanır.

Rope Grips

Fmax 2.5 kN

Advantages and features

  • 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.

Function description

Sarmal çene, çekme numunelerin sıkıştırılmasında kullanılabilinir.

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.

Grips for High-Strength Ropes

Fmax 10 kN and Fmax 50 kN
  • Specimen material:
    plastics, textiles, metals
  • Specimen shape:
    ropes, high-strength yarns, cables, wire
  • Type of loading:
    tensile

Advantages and features

  • 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 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.

Function description

Sarmal çene, çekme numunelerin sıkıştırılmasında kullanılabilinir.

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.

Grips for Ropes and Steel

Fmax 100 kN

Advantages and features

  • 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.

Function description

Sarmal çene, çekme numunelerin sıkıştırılmasında kullanılabilinir.

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

Grips for Ropes and Yarns

Ideal for compressible ropes, assemblies and soft wires, Fmax 100 kN.
  • Specimen material:
    plastics, textiles, metals
  • Specimen shape:
    ropes, high-strength yarns, cables, wire
  • Type of loading:
    tensile

Advantages and features

  • 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.

Function description

Sarmal çene, çekme numunelerin sıkıştırılmasında kullanılabilinir.

  • large-diameter roller for rigid ropes (wire, wire ropes)
  • small-diameter roller for flexible ropes (natural fiber, man-made 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.

Technical Overview

Specimen grips for ropes are available from Fmax 2.5 kN to Fmax 100 kN test loads.
