- Scrubbers (scrubber refurbishment, split riding rings, split gear)
Procurement & Supply Chain
"Optimized equipment procurement & mineral spare logistics across sub-Saharan operations."
Securing critical heavy spares, excavation consumables, and structural components requires responsive supplier relationships and resilient logistics. We leverage regional hubs in Johannesburg, Harare, Kolwezi, and Abidjan to orchestrate supply chains for major mining clients, reducing lead times and minimizing operational downtime.
Procurement Deliverables
- Placement of orders with global supplier networks
- Inspection of manufacturing process and final inspection of finished goods
- Testing and certifying of equipment before shipment
- Transportation, freight logistics, and customs clearance of goods
- Storage of goods at secure consolidation depots before transportation
- Monitoring of overseas manufacturing facilities in China
- Supply and delivery of grinding mills, crushers, screens, gearboxes, and replacement spares
- Provision of SADC certificates and certificates of origin for customs duty cost savings
Project Delivery & Turnkey Solutions
"Turnkey site prep and civil earthworks executed within exact tolerances."
From initial bush clearing and topsoil stripping to precision sub-base grading and heavy concrete foundations, we manage the complete civil execution lifecycle. Using Trimble GPS-guided earthmoving fleets and structural crane machinery, our certified engineers deliver complex layouts ahead of time.
