Drill Rig Maintenance
Duration:
2021-2023
Scope:
ECCS assist in daily maintenance service activities on
Pantera, Epiroc and CAT Drills. ECCS also provides detailed reliability
reporting on all auxiliary equipment, the reporting focus on equipment
failures, availability, Mean Time To Repair (MTTR) and Mean Time To
Failure (MTTF). The maintenance work includes but is not limited to:
1. Daily servicing and inspecting of drills.
2. Task preparation.
3. Cleaning equipment before maintenance activities.
4. Failure component replacement.
5. Preventative maintenance.
6. Investigating unplanned failures according to the Root Cause
7. Failure Analysis (RCFA) process and providing recommendations.
ECCS supports daily maintenance by inspecting and servicing the drills. We assist in component replacement and maintenance, by reporting defects and advising on spare part requirements or modifications. The team also assists by performing reliability studies and reporting on the equipment failures, availability, MTTR and MTTF. We also perform RCFA to investigate unplanned and/or repetitive failures.
1. Maintenance planning and equipment replacement
2. OEM liaising with equipment modification
3. RCFA, MTTF and MTTR services
4. Reliability engineering
5. Machine performance and digitisation
6. Digital reporting
Coal waste system maintenance
Duration:
2020-2022
Scope:
Extensive structural repairs are required on the system
as the system dates from the 1980’s. Significant wear is expected on the
feeders and the 2100 and 2200 belts. Boilermakers, millwrights and
electricians are provided by ECCS to aid the IPC & Discard’s electrical
team as well as testing and fixing pull keys along the extent of all belts.
The ECCS maintenance team assists in all mechanical and electrical
work that is required. ECCS assists with fitting work thus having a dual
role within the hierarchy. Each artisan is assisted with an artisan aid to
ensure that the expensive resources are optimally utilised.
ECCS provides servicing and maintenance on conveyor belt systems. Assist in condition monitoring and fault finding in order to provide solutions and improve the system. Perform planned maintenance on a regular basis as well as maintenance during breakdowns and shutdowns.
1. Complete conveyor system/spreader maintenance
2. Equipment modification
3. Root cause failure analysis
4. Reliability engineering
SHOVEL LIFTING EQUIPMENT DESIGN REVIEW
Duration:
2022
Scope:
ECCS provides repair and maintenance services for all mining equipment operational at the site. Including equipment that are scheduled for major and half-life maintenance interventions. These interventions require the top and bottom sections of the shovels to be separated to reach, remove and replace or repair certain components. The ECCS maintenance team contributes significantly to the effective maintenance and operational practices on site. ECCS will provide an adequate lifting mechanism. In order to ensure that the sourced lifting equipment is suitable, safe and functional, it is required that a thorough design review be conducted to ensure an optimal operating lifting solution with minimum human interaction.
• Conduct a design review of the hydraulic lifting equipment.
• Verifying of the functionality of the lifting equipment.
• Analyse the lifting procedure for safe operation, identify potential failures and provide recommendations and control measures in the identified failures.
• Conduct a Failure Mode Effects Analysis.
• Review of manufacturing specifications including material specifications and data sheets.
• Failure Mode and Effects Analysis (FMEA).
• Signing off the design, design review report and drawings by a registered Professional Engineer.
• Conduct onsite field assessment of the Shovel Equipment to ensure adequate integration of the hydraulic lifting equipment with the Shovels.
DRAWING REVIEW
Duration:
2022
Scope:
The truck rebuild maintenance team provides repair and rebuild services on a fleet of Haul trucks. These services require that the truck’s wheels should be removed in order to create access for personnel to work on the electric wheel motors and other hard-to-reach areas. Pre-manufactured stands are required to keep the truck body lifted and all areas accessible to work on. Three different types of stands are utilised for this purpose. Each of these stands should be able to carry 100 tons safely. To ensure that the mechanisms are safe, functional and suitable to work as lifting equipment, a full design review is required to ensure the stands are safe to use.
• Create a design review of the truck trestles.
• Conduct a Finite Element Analysis (FEA).
• Review of manufacturing drawings.
• Conduct a Failure Mode and Effects Analysis (FMEA).
• Signing off the design, design review report and drawings by a registered Professional Engineer.
SAND BLASTING
Duration:
2022
Scope:
ECCS provides all labour to perform pre-surface preparation, sandblasting and paintwork. All work is completed safely within the planned timelines for a limited duration. ECCS uses one site supervisor, two sandblasters and two painters.
The team performs work on all manufactured and refurbished steel structures including beams, plate work, chutes, frames, support structures and dump bodies. Depending on the plant maintenance requirements, the sizes, quantities, and frequency of job requests are random from clients.
