Reliable High Performance

Steel wire ropes are regarded as critical components of a lifting appliance and must be capable of meeting the varied demands that are placed upon them, whether they are related to breaking force, bending strength, abrasion or rotation resistance. In order to meet these demands, the construction of DIEPA special wire ropes combined with the advanced machinery and methods that are employed to produce them, are the culmination of decades of intensive research and development, resulting in a high degree of in-service rope structural stability. This means that they are capable of performing under the most demanding of loading conditions. And, of course, the above-average service life brings economic benefits, too. DIEPA special wire ropes are designed and manufactured to afford a higher level of in-service rope safety and reliability, particularly when they are operating in situations where high loading is experienced and/or critical operating conditions prevail.

Rope Constructions

Experience gleaned from manufacturing processes and application technology along with ultra-modern computing software have been brought together to achieve the optimum rope construction of DIEPA special wire ropes.

Wire Material

DIEPA only processes exceptionally high quality wire materials which go far beyond the requirements stipulated by the relevant standards. DIEPA works exclusively with experienced and reliable wire manufacturers with which it has built up a solid working relationship spanning many years.

Rope Containing Plastic

For decades now DIEPA has manufactured special wire ropes containing plastic, too. Only ultra-modern plastics such as polyamide 12 are employed.

Rope Lubricant

The interior of the strands and the rope are critical points in the rope structure. This is why they are filled with special lubricant during the individual stranding operation itself. This serves to inhibit the onset of internal corrosion, something especially important for prolonged service.

Manufacturing Techniques

The ultra-modern machines we employ produce the highest level of precision during the stranding process. Every DIEPA special wire rope up to a diameter of 120 mm and its components are manufactured on machines especially optimised for this purpose and operated by qualified manufacturing staff.
