In-House Wire Stretching & Test Bed

Posted by Miami Stainless on 08-Jan-2020 10:00:00

Miami Stainless is proud to announce the launch of our new 20 metre, 80 tonne testing and wire rope stretching bed.  This state of the art test bed is specially designed for pre-installation stretching of wire and non-destructive and destructive testing of steel wire ropes, synthetic ropes, chains, shackles.

Wire Pre-Stretching

Pre-stretching is the repeated application of a predetermined load to a finished structural wire rope.  This is generally required in applications such as:

  • To make the strand and rope more elastic by removing the constructional stretch inherent in the wire as it comes from the stranding and closing machines. This is essential for most suspended or guyed structures, since it ensures the stretch parameters used by the designer in predicting the elastic behaviour of the cables after installation.
  • To permit measuring and marking at prescribed loads of the strand and rope assemblies.

Wire rope pre-stretching is normally required for large diameter wire rope, normally 8mm and over, for applications such as:

      • Suspension bridges
      • Shade structures - carpark shade sails
      • Structural shade membranes - sporting stadium roofing

Need a very long cable?  We can test up to an unlimited length.
Not a problem, we can test up to 20 metres in one section however the unique design allows for testing up to any length of cable as the cable can be tested in sections by passing it through the hydraulic cable grips and testing each subsequent section.

Need a large diameter cable tested?   
Our machine will test up to 32mm diameter wire rope.



Product Testing

Miami Stainless will also be using the new test bed for conformance testing of our stainless steel hardware products, wire rope and chain.  All our stainless steel product are manufactured to meet Australian Standards.  

This in-house test bed will now provide a secondary testing facility to ensure that all Miami Stainless products comply with the standards and meet the specifications and break-loads as stated in our product information guides.
