Preface about rope use


A wire rope can be described in simple terms as an assembly of several strands laid helically in different possible arrangements, in order to bear axial loads. To be fit for purpose, it must also meet other criteria, such as resistance to side loads, flexibility, handling and stability.


This definition, however, does not fully reflect the increasingly challenging requirements of wire rope design, manufacture, use and inspection for the oil and gas sector. Ropes for these applications make an essential contribution to efficiency and reliability, and of course, the fundamental consideration for any rope in any application is safety compliance.

To ensure high quality standards, our company has developed a comprehensive design and manufacturing process, which includes custom design software, state of the art manufacturing equipment and skilled personnel with proven expertise. 

The content of this catalogue is a brief abstract of wire rope characteristics and recommendations for use in the oil and gas industry.

Our highly skilled technical team are available to provide support for specific customer requirements, and welcome the opportunity to work together to provide solutions for any complex technical issues.










Strand: An element of rope consisting of an assembly of wires of appropriate shape and dimensions laid helically in the same direction in one or more layers around a centre.

Stranded rope: An assembly of several strands laid helically in one or more layers around a core (single-layer rope) or centre (rotation resistant or parallel-closed rope).

Rope class: A grouping of ropes of similar mechanical properties and physical characteristics.

Rope construction: The detail and arrangement of the various elements of the rope.

Minimum breaking force: Specified value in kN, below which the measured breaking force is not allowed to fall in a prescribed breaking force test and normally obtained by calculation from the product of the square of the nominal diameter, the rope grade and the breaking force factor

ABF/ABL: Actual Breaking Force. Actual Breaking Force is commonly referred to as Actual Breaking Load (ABL). These two terms mean the same thing. The force (load) required to cause a wire rope to fail by fracture or distorting to such an extent that the load is released. This is not to be confused with aggregate breaking force, which is the sum of the breaking forces of the wires composing the rope.
