ncrete crusher repair in angola

Repairing a concrete crusher in Angola requires careful planning, sourcing of parts, and skilled labor due to the country’s logistical challenges. Here’s a step-by-step guide to help you with the repair process:

1. Identify the Problem
– Conduct a thorough inspection to determine the cause of failure (e.g., worn-out jaws, hydraulic leaks, electrical faults, or structural cracks).
– Check common wear parts like hammers, liners, bearings, and belts.

2. Source Replacement Parts
– Local Suppliers: Check if Angola-based suppliers (e.g., in Luanda or Lubango) stock crusher parts.
– International Suppliers: If parts are unavailable locally, order from manufacturers (e.g., Metso, Sandvik, Terex) or global suppliers (like Crusher Spares Ltd).
– Consider air freight for urgent shipments due to Angola’s slow port clearances.

3. Find Skilled Technicians
– Hire local heavy equipment mechanics with crusher repair experience.
– If expertise is lacking, bring in technicians from neighboring countries (South Africa, Namibia) or arrange manufacturer support.

4. Perform Repairs
– Replace damaged components (bearings, shafts, hydraulic cylinders).
– Weld structural cracks if necessary.
– Rebuild or replace worn-out crushing jaws/mantles.
– Test hydraulic and electrical systems for leaks/shorts.

5. Maintenance Tips to Prevent Future Issues
– Regularly lubricate bearings and moving parts.
– Inspect wear parts frequently.
– Keep spare parts on hand for quick replacements.

6. Challenges in Angola
– Logistics: Delays in importing parts; plan ahead.
– Power Supply: Ensure stable electricity or use generators.
– Corrosion: Coastal areas may accelerate wear; use corrosion-resistant materials.

7. Local Contacts & Resources
– Equipment Dealers:
– Liebherr Angola
– Mantrac Angola (Caterpillar dealer)
– ELB Equipment (South Africa-based but services Angola)
– Workshops: Look for heavy machinery repair shops in Luanda or Lobito.
