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
• Reclaimers
• Shiploaders
• Spreaders
• Trippers
• Train loading stations
• Wagon tipplers
• Conveyor gantries
• Take-up towers
• 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

• perational environments
• Finite Element Analysis

results and structural inspection reports are used to estimate expectancies

Structural and machine design

• Detail structural designs completed to

client requirements

• Designs consist of:
• Detailed layouts
• Supporting calculations to design

specifications including, ISO, SANS and FEM

• Finite Element analyses of complete

structures/ identified components

• Detailed manufacturing data packs
