Nine Dot Solutions Consulting Mechanical Engineers Pieter van Zyl
About Nine Dot Nine Dot is a consulting engineering company that specialises in structural analysis and design Specialities include - Structural audits and failure analyses by means of Finite Element Analysis - Wireless engineering data measurements and data manipulation - Bulk material structure refurbishments and capacity upgrades - Detail designs and manufacturing data packs - Conceptual layouts and order of magnitude calculations - New product design and development
Structural and design auditing - Structural audits to ISO, FEM, SANS or Similar - Failure investigations and root cause analyses - Capacity upgrades and refurbishment procedures
• • Stackers Train loading stations • • Reclaimers Wagon tipplers • • Shiploaders Conveyor gantries • • Spreaders Take-up towers • • Trippers General equipment
Wireless measurements - Can measure the following: - Stress/Strain - Pressure - Measurements can be taken for evaluation or continuous monitoring purposes
Refurbishments, capacity upgrades and modifications - Finite Element Analysis results and supporting calculations are used as base line for refurbishment plans and possible capacity upgrades
Bucket Wheel Reclaimer capacity upgrade 1775tph – 2250tph
Detailed installation procedure Manufacturing drawings of new/modified equipment
Addition of Tippler top stop mechanism
Slew bearing analysis - Analysis techniques are used to accurately simulate slew bearing element forces - Results are used to calculate expected bearing life based on structural configuration and construction details
Equipment replacement studies - Bulk material structures have finite life, due to harsh operational environments - Finite Element Analysis results and structural inspection reports are used to estimate expectancies
