WireCo synthetic pendants: fatigue and asset life insights for mine engineers
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
WireCo has identified vibration and shock transfer as a major driver of structural fatigue in draglines and electric rope shovels, and is promoting its UNION Gladiator synthetic pendants to reduce these dynamic loads. By replacing traditional steel pendants with synthetic elements, the system is designed to dampen impact forces transmitted through the boom and rigging, lowering peak stresses on critical welds and chord members. The approach targets mines operating equipment at higher duty cycles, aiming to extend structural life and defer major rebuilds or replacements.
Technical Brief
- UNION Gladiator pendants use synthetic fibre rope elements in place of traditional steel bar assemblies.
- WireCo targets draglines and electric rope shovels where boom and mast welds show fatigue cracking.
- Synthetic pendants introduce compliance in the load path, moderating high-frequency load spikes into the structure.
- Lower transferred shock loads reduce risk of brittle fracture at welded boom-chord and lug connections.
- Reduced vibration transmission can lessen loosening of bolted joints and associated inspection/retightening requirements.
- WireCo positions the pendants as a retrofit option, avoiding major structural modifications or boom redesign.
Our Take
For operators, swapping to synthetic pendants is typically a low-capex intervention compared with structural upgrades, which in our database often makes such products attractive for mines nearing mid-life that want to defer major replacement of primary lifting equipment.
Vendors like WireCo that can demonstrate quantifiable reductions in equipment stress tend to gain traction in safety-driven procurement processes, as many mines in our recent Mining coverage are under pressure to show measurable improvements in both asset integrity and personnel safety metrics.
