Practical repair and fabrication solutions for heavy equipment that falls outside standard categories.
CBU is not limited to a specific equipment brand. Repair work is approached around the component, damage, operating requirement and practical engineering solution.
Major Repair Capability
Repair the Damage. Restore the Machine.
Heavy mining equipment operates under extreme loads, abrasion and repeated structural stress. CBU Engineering repairs and rebuilds critical structures and components with the objective of restoring strength, function and dependable service life.
Heavy Repair & Rebuild
Major Repairs Require More Than a Quick Fix.
Damaged structures and high-load components are assessed around the cause of failure, operating conditions and the repair required to return the equipment to service.

Frames & Chassis
Repair of damaged, fatigued and high-stress structures.
Buckets & Attachments

Track & Undercarriage Structures
Repair and restoration of heavy fabricated structures.
Repair decisions are made around the actual damage. Depending on the component and failure, work can involve removal of damaged material, structural repair, reinforcement, fabrication, machining, wear protection and final reassembly — rather than simply replacing an entire assembly.
Repair & Rebuild Process
A Controlled Process. From Damage to Service.
Major mining-equipment repairs require more than restoring appearance. CBU follows the repair through assessment, preparation, structural work, fabrication or machining, reassembly and final inspection before the component or machine returns to service.
Inspect & Assess
The damage, wear, cracking and surrounding structure are assessed to establish the extent of the repair and the practical route forward.
Strip & Prepare
Damaged material, worn sections and affected components are exposed and prepared so the repair can be carried out correctly.
Repair & Reinforce
Structural damage and cracks are repaired, with reinforcement introduced where the application and repair requirement call for it.
Fabricate & Machine
Replacement sections, brackets, bushes, pins and other required components can be fabricated or machined as part of the same repair.
Reassemble & Finish
Repaired assemblies are rebuilt and completed, with final fitment and finishing carried out around the requirements of the job.
Final Inspection
Completed work is checked before release so the repaired machine, attachment or component is ready to return to service.
The exact repair sequence depends on the machine and the damage. Structural repair, fabrication, machining and wear protection can be combined into one coordinated rebuild rather than treated as unrelated jobs.
Workshop + Field Capability
The Repair Goes Where It Needs To.
Some repairs need the controlled environment and equipment of a workshop. Others need to happen where the machine is standing. CBU Engineering supports both — allowing the repair strategy to be built around the equipment, the damage and the operational requirement.
Major Repairs & Controlled Rebuilds
Extensive repair work can be completed in the workshop, bringing structural repair, fabrication, machining and component work together within one coordinated rebuild.
- Major structural rebuilds
- Heavy fabrication
- Machining & component work
- Bucket & attachment rebuilds
- Crack repair & reinforcement
- Wear-component replacement
Engineering Support at the Machine
When transporting the equipment is impractical or downtime is critical, CBU can support repair, assessment and engineering work directly at mining and industrial sites.
- On-site equipment repairs
- Breakdown assistance
- Mobile welding
- On-site fabrication
- Planned maintenance support
- Shutdown project support
Workshop capability and field support can operate as one repair solution.
Components can be removed and rebuilt in the workshop while
associated preparation, inspection or installation work is
coordinated on site.

Repair vs Replacement
Replace When Necessary. Rebuild When It Makes Sense.
Heavy mining equipment represents significant capital. Damage to a structure, attachment or component does not automatically mean the entire assembly has reached the end of its useful life. The first question should be what can be safely and practically restored.
Restore the Asset You Already Own
Where the underlying equipment remains viable, a properly planned repair can restore damaged and worn areas without unnecessarily replacing the complete machine or assembly.
- Retain serviceable major structures and components
- Replace damaged or worn sections where required
- Repair cracks and high-stress structural areas
- Introduce wear protection or reinforcement where appropriate
- Coordinate fabrication and machining within the rebuild
Sometimes Replacement Is the Correct Decision
Not every component should be repaired. Excessive damage, unsuitable material condition or the economics of the repair may make replacement the more practical route.
- Damage extends beyond a practical repair scope
- Critical material or structural integrity is compromised
- Repair cost approaches replacement value
- Continued repair would not provide reasonable service life
- Replacement better supports the operational requirement
The objective is not to repair everything.
It is to make the right engineering decision.
CBU Engineering assesses the condition and repair requirement so the work performed makes practical sense for the equipment, its application and its expected return to service.
Retain usable equipment and components where a practical repair remains viable.
Build the repair scope around restoring productive equipment to operation.
Target damaged, worn and high-stress areas rather than automatically replacing complete assemblies.
Restore viable structures and components for continued operation in demanding environments.
Integrated Repair Capability
One Repair. Multiple Engineering Disciplines.
A major mining-equipment repair rarely involves only one discipline. Structural work, fabrication, machining and wear protection often need to work together as part of the same rebuild. CBU brings those capabilities together around the repair requirement.
Restore Critical Load-Bearing Structures
Repair of cracking, deformation, fatigue damage and compromised structural areas on heavy equipment, attachments and fabricated assemblies.
Explore Structural RepairsRebuild What Cannot Simply Be Replaced
Heavy fabrication supports replacement sections, brackets, structures, guards, attachments and custom components required during major equipment repairs.
Explore FabricationPrecision Components for the Rebuild
Machining capability supports the repair with pins, bushes, shafts, bores and other components where dimensional accuracy and correct fit are critical.
Explore MachiningProtect the Areas That Take the Punishment
Wear-resistant materials, liners and reinforcement can be incorporated into repair and refurbishment work where abrasion and impact are driving premature component wear.
Explore Wear Solutions
One job does not need to be split between four unrelated suppliers.
CBU can coordinate structural repair, fabrication, machining and wear protection as interconnected parts of the same equipment repair or rebuild.
